NCP3335A

Ultra High Accuracy,

Low Iq, 500 mA

Low Dropout Regulator

The NCP3335A is a high performance, low dropout regulator with

accuracy of ±0.9% over line and load. This device features ultra−low

quiescent current and noise which encompasses all necessary

characteristics demanded by today’s consumer electronics. This

unique device is guaranteed to be stable without a minimum load

current requirement and stable with any type of capacitor as small as

1.0 mF. The NCP3335A also comes equipped with sense and noise

reduction pins to increase the overall utility of the device and offers

reverse bias protection.

Features

•High Accuracy Over Line and Load (±0.9% at 25°C)

•Ultra−Low Dropout Voltage at Full Load (260 mV typ.)

•No Minimum Output Current Required for Stability

•Low Noise (31 mVrms w/10 nF Cnr and 51 mVrms w/out Cnr)

•Low Shutdown Current (0.07 mA)

•Reverse Bias Protected

•2.6 V to 12 V Supply Range

•Thermal Shutdown Protection

•Current Limitation

•Requires Only 1.0 mF Output Capacitance for Stability

•Stable with Any Type of Capacitor (including MLCC)

•Available in 1.5 V, 1.8 V, 2.5 V, 2.8 V, 2.85 V, 3.0 V, 3.3 V, 5.0 V and

Adjustable Output Voltages

•These are Pb−Free Devices

Applications

•PCMCIA Card

•Cellular Phones

•Camcoders and Cameras

•Networking Systems, DSL/Cable Modems

•Cable Set−Top Box

•MP3/CD Players

•DSP Supply

•Displays and Monitors

APPLICATIONS INFORMATION

Reverse Bias Protection

Reverse bias is a condition caused when the input voltage

goes to zero, but the output voltage is kept high either by a

large output capacitor or another source in the application

which feeds the output pin.

Normally in a bipolar LDO all the current will flow from

the output pin to input pin through the PN junction with

limited current capability and with the potential to destroy

the IC.

Due to an improved architecture, the NCP3335A can

withstand up to 7.0 V on the output pin with virtually no

current flowing from output pin to input pin, and only

negligible amount of current (tens of mA) flowing from the

output pin to ground for infinite duration.

Input Capacitor

An input capacitor of at least 1.0 mF, any type, is

recommended to improve the transient response of the

regulator and/or if the regulator is located more than a few

inches from the power source. It will also reduce the circuit’s

sensitivity to the input line impedance at high frequencies.

The capacitor should be mounted with the shortest possible

track length directly across the regular’s input terminals.

Output Capacitor

The NCP3335A remains stable with any type of capacitor

as long as it fulfills its 1.0 mF requirement. There are no

constraints on the minimum ESR and it will remain stable up

to an ESR of 5.0 W. Larger capacitor values will improve the

noise rejection and load transient response.

Noise Reduction Pin

Output noise can be greatly reduced by connecting a 10 nF

capacitor (Cnr) between the noise reduction pin and ground

(see Figure 1). In applications where very low noise is not

required, the noise reduction pin can be left unconnected.

For the adjustable version, in addition to the 10 nF Cnr, a

68 pF capacitor connected in parallel with R1 (see Figure 2)

is recommended to further reduce output noise and improve

stability.

Adjustable Operation

The output voltage can be set by using a resistor divider

as shown in Figure 2 with a range of 1.25 to 10 V. The

appropriate resistor divider can be found by solving the

equation below. The recommended current through the

resistor divider is from 10 mA to 100 mA. This can be

accomplished by selecting resistors in the kW range. As

result, the Iadj*R2 becomes negligible in the equation and

can be ignored.

Vout +1.25 * ǒ1)R1

R2Ǔ)Iadj *R2 (eq. 1)

Example:

For Vout = 2.9 V, can use R1 = 36 kW and R2 = 27 kW.

1.25 * ǒ1)36 kW

27 kWǓ+2.91 V (eq. 2)

Dropout Voltage

The voltage dropout is measured at 97% of the nominal

output voltage.

Thermal Considerations

Internal thermal limiting circuitry is provided to protect the

integrated circuit in the event that the maximum junction

temperature is exceeded. This feature provides protection

from a catastrophic device failure due to accidental

overheating. This protection feature is not intended to be used

as a substitute to heat sinking. The maximum power that can

be dissipated, can be calculated with the equation below:

PD+TJ(max) *TA

RqJA

(eq. 3)

For improved thermal performance, contact the factory

for the DFN package option. The DFN package includes an

exposed metal pad that is specifically designed to reduce the

junction to air thermal resistance, RqJA.
