Caution The above connection diagram and constants will not guarantee successful operation. Perform

thorough evaluation using an actual application to set the constants.

 Condition of Application

Input capacitor (CIN): A ceramic capacitor with capacitance of 1.0 μF or more is recommended.

Output capacitor (CL): A ceramic capacitor with capacitance of 1.0 μF to 100 μF is recommended.

Caution Generally, in a voltage regulator, an oscillation may occur depending on the selection of the external

parts. Perform thorough evaluation including the temperature characteristics with an actual

application using the above capacitors to confirm no oscillation occurs.

 Selection of Input Capacitor (CIN) and Output Capacitor (CL)

The S-19212BxxA Series requires CL between the VOUT pin and the VSS pin for phase compensation. The operation

is stabilized by a ceramic capacitor with capacitance of 1.0 μF to 100 μF. When using an OS capacitor, a tantalum

capacitor or an aluminum electrolytic capacitor, the capacitance also must be 1.0 μF to 100 μF. However, an oscillation

may occur depending on the equivalent series resistance (ESR).

Moreover, the S-19212BxxA Series requires CIN between the VIN pin and the VSS pin for a stable operation.

Generally, an oscillaiton may occur when a voltage regulator is used under the conditon that the impedance of the

power supply is high.

Note that the output voltage transient characteristics varies depending on the capacitance of CIN and CL and the value

of ESR.

Caution Perform thorough evaluation including the temperature characteristics with an actual application to

select CIN and CL.

 Operation

1. Basic operation

Figure 14 shows the block diagram of the S-19212BxxA Series to describe the basic operation.

The error amplifier compares the feedback voltage (Vfb) whose output voltage (VOUT) is divided by the feedback

resistors (Rs and Rf) with the reference voltage (Vref). The error amplifier controls the output transistor,

consequently, the regulator starts the operation that holds VOUT constant without the influence of the input voltage

(VIN).

Figure 14

2. Output transistor

In the S-19212BxxA Series, a low on-resistance P-channel MOS FET is used between the VIN pin and the VOUT

pin as the output transistor. In order to hold VOUT constant, the on-resistance of the output transistor varies

appropriately according to the output current (IOUT).

Caution Since a parasitic diode exists between the VIN pin and the VOUT pin due to the structure of the

transistor, the IC may be damaged by a reverse current if VOUT becomes higher than VIN.

Therefore, be sure that VOUT does not exceed VIN + 0.3 V.

S-19212BxxA Series Rev.4.0_00

3. ON / OFF pin

The ON / OFF pin controls the internal circuit and the output transistor in order to start and stop the regulator. When

the ON / OFF pin is set to OFF, the internal circuit stops operating and the output transistor between the VIN pin

and the VOUT pin is turned off, reducing current consumption significantly.

The internal equivalent circuit related to the ON / OFF pin is configured as shown in Figure 15. Since the ON / OFF

pin is neither pulled down nor pulled up, do not use it in the floating status. When not using the ON / OFF pin,

connect it to the VIN pin. Note that the current consumption increases when a voltage of 0.25 V to VIN − 0.3 V is

applied to the ON / OFF pin.

B "H": ON Operate Constant value*1 ISS1

B "L": OFF Stop Pulled down to VSS*2 ISS2

*1. The constant value is output due to the regulating based on the set output voltage value.

*2. The VOUT pin voltage is pulled down to VSS due to the discharge shunt circuit (RLOW = 70 kΩ typ.), the

feedback resistors (Rs and Rf) and a load.

4. Overcurrent protection circuit

The S-19212BxxA Series has a built-in overcurrent protection circuit to limit the overcurrent of the output transistor.

When the VOUT pin is shorted with the VSS pin, that is, at the time of the output short-circuit, the output current is

limited to 120 mA typ. due to the overcurrent protection circuit operation. The S-19212BxxA Series restarts

regulating when the output transistor is released from the overcurrent status.

Caution 1. This overcurrent protection circuit does not work as for thermal protection. For example, when

the output transistor keeps the overcurrent status long at the time of output short-circuit or

due to other reasons, pay attention to the conditions of the input voltage and the load current

so as not to exceed the power dissipation.

2. Note that any interference may be caused in the output voltage start-up when a load heavier

than

VOUT(S)

100 mA is connected.

increases to 165°C typ., the thermal shutdown circuit becomes the detection status, and the regulating is stopped.

When the junction temperature decreases to 140°C typ., the thermal shutdown circuit becomes the release status,

and the regulator is restarted.

If the thermal shutdown circuit becomes the detection status due to self-heating, the regulating is stopped and VOUT

decreases. For this reason, the self-heating is limited and the temperature of the IC decreases. The thermal

shutdown circuit becomes release status when the temperature of the IC decreases, and the regulating is restarted,

thus the self-heating is generated again. Repeating this procedure makes the waveform of VOUT into a pulse-like

form. This phenomenon continues unless decreasing either or both of the input voltage and the output current in

order to reduce the internal power consumption, or decreasing the ambient temperature. Note that the product may

suffer physical damage such as deterioration if the above phenomenon occurs continuously.

Caution 1. When the heat radiation of the application is not in a good condition, the self-heating cannot be

limited immediately, and the IC may suffer physical damage. Perform thorough evaluation

including the temperature characteristics with an actual application to confirm no problems

happen.

2. If a large load current flows during the restart process of regulating after the thermal shutdown

circuit changes to the release status from the detection status, the thermal shutdown circuit

becomes the detection status again due to self-heating, and a problem may happen in the

restart of regulating. A large load current, for example, occurs when charging to the CL whose

capacitance is large.

Perform thorough evaluation including the temperature characteristics with an actual

application to select CL.

 Precautions

• Generally, when a voltage regulator is used under the condition that the load current value is small (0.1 mA or less),

the output voltage may increase due to the leakage current of an output transistor.

• Generally, when a voltage regulator is used under the condition that the temperature is high, the output voltage may

increase due to the leakage current of an output transistor.

• Generally, when the ON / OFF pin is used under the condition of OFF, the output voltage may increase due to the

leakage current of an output transistor.

• Generally, when a voltage regulator is used under the condition that the impedance of the power supply is high, an

oscillation may occur. Perform thorough evaluation including the temperature characteristics with an actual

application to select CIN.

• Generally, in a voltage regulator, an oscillation may occur depending on the selection of the external parts. The

following use conditions are recommended in the S-19212BxxA Series, however, perform thorough evaluation

including the temperature characteristics with an actual application to select CIN and CL.

Input capacitor (CIN): A ceramic capacitor with capacitance of 1.0 μF or more is recommended.

Output capacitor (CL): A ceramic capacitor with capacitance of 1.0 μF to 100 μF is recommended.

• Generally, in a voltage regulator, the values of an overshoot and an undershoot in the output voltage vary

depending on the variation factors of input voltage start-up, input voltage fluctuation and load fluctuation etc., or the

capacitance of CIN or CL and the value of the equivalent series resistance (ESR), which may cause a problem to the

stable operation. Perform thorough evaluation including the temperature characteristics with an actual application to

select CIN and CL.

• Generally, in a voltage regulator, an overshoot may occur in the output voltage momentarily if the input voltage

steeply changes when the input voltage is started up or the input voltage fluctuates etc. Perform thorough evaluation

including the temperature characteristics with an actual application to confirm no problems happen.

• Generally, in a voltage regulator, if the VOUT pin is steeply shorted with GND, a negative voltage exceeding the

absolute maximum ratings may occur in the VOUT pin due to resonance phenomenon of the inductance and the

capacitance including CL on the application. The resonance phenomenon is expected to be weakened by inserting a

series resistor into the resonance path, and the negative voltage is expected to be limited by inserting a protection

diode between the VOUT pin and the VSS pin.

• If the input voltage is started up steeply under the condition that the capacitance of CL is large, the thermal

shutdown circuit may be in the detection status by self-heating due to the charge current to CL.

• Make sure of the conditions for the input voltage, output voltage and the load current so that the internal loss does

not exceed the power dissipation.

• Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic

protection circuit.

• When considering the output current value that the IC is able to output, make sure of the output current value

specified in Table 10 in " Electrical Characteristics" and footnote *4 of the table.

• Wiring patterns on the application related to the VIN pin, the VOUT pin and the VSS pin should be designed so that

the impedance is low. When mounting CIN between the VIN pin and the VSS pin and CL between the VOUT pin and

the VSS pin, connect the capacitors as close as possible to the respective destination pins of the IC.

• In the package equipped with heat sink of backside, mount the heat sink firmly. Since the heat radiation differs

according to the condition of the application, perform thorough evaluation with an actual application to confirm no

problems happen.

• SII Semiconductor Corporation claims no responsibility for any disputes arising out of or in connection with any

infringement by products including this IC of patents owned by a third party.
