TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic

TCR3UG series

Ultra low quiescent current, Fast Load Transient 300 mA CMOS Low Drop-Out Regulator in ultra

small package

1. Description

The TCR3UG series are CMOS general-purpose single-output

voltage regulators with an on/off control input, featuring ultra low

quiescent bias current and low dropout voltage.

These voltage regulators are available in fixed output voltages

between 0.8 V and 5.0 V and capable of driving up to 300 mA.

They feature Over-current protection, Thermal Shutdown function

and Auto-discharge option.

The TCR3UG series is offered in the ultra small plastic mold

package WCSP4F (0.645 mm x 0.645 mm; t 0.33 mm (max)) and

has a low dropout voltage of 155 mV (3.3 V output, IOUT = 300

mA). As small ceramic input and output capacitors 1μF can be used with the TCR3UG series, these devices

are ideal for portable applications that require high-density board assembly such as cellular phones.

8. Application Note

8.1. Recommended Application Circuit

The figure above shows the recommended configuration for using a Low-Dropout regulator. Insert a

capacitor at VOUT and VIN pins for stable input/output operation. (Ceramic capacitors can be used).

Board-mounted power dissipation ratings are available in the Absolute Maximum Ratings table.

Power dissipation is measured on the board condition shown below.

8.3. Attention in Use

● Output Capacitors

Ceramic capacitors can be used for these devices. However, because of the type of the capacitors, there

might be unexpected thermal features. Please consider application condition for selecting capacitors. And

Toshiba recommend the ESR of ceramic capacitor is under 10 Ω.

COUT is not necessary. But for stable operation, we recommend over 0.1μF.

● Mounting

The long distance between IC and output capacitor might affect phase assurance by impedance in wire

and inductor. For stable power supply, output capacitor need to mount near IC as much as possible. Also

VIN and GND pattern need to be large and make the wire impedance small as possible.

● Permissible Loss

Please have enough design patterns for expected maximum permissible loss. And under consideration of

surrounding temperature, input voltage, and output current etc., we recommend proper dissipation ratings

for maximum permissible loss; in general maximum dissipation rating is 70 to 80 %.

● Over current Protection and Thermal shut down function

Over current protection and Thermal shut down function are designed in these products, but these are not

designed to constantly ensure the suppression of the device within operation limits. Depending on the

condition during actual usage, it could affect the electrical characteristic specification and reliability. Also

note that if output pins and GND pins are not completely shorted out, these products might be break down.

When using these products, please read through and understand the concept of dissipation for absolute

maximum ratings from the above mention or our ‘Semiconductor Reliability Handbook’. Then use these

products under absolute maximum ratings in any condition. Furthermore, Toshiba recommend inserting

failsafe system into the design.
