AS1367

150mA, Adaptive Low Drop-Out Linear Regulator

1 General Description

2 Key Features

ꢀ

Low Dropout Voltage: 110mV @ 150mA load

Operating Input Voltage Range: 2.0V to 5.5V

Output Voltage Range: 1.2V to 5.0V (50mV steps)

Max. Output Current: 150mA

The AS1367 is a precise, low noise, high speed, low

dropout regulator with adaptive operation. Features

included are high ripple rejection and low dropout volt-

age, a reference voltage source, an error amplifier and a

current limiter.

Low Shutdown Current: 100nA

The AS1367 provides high speed operation, low power

consumption and high efficiency by automatically

switching between a light load and a heavy load mode

depending upon the output current level.

High PSRR: 60dB @ 10kHz

Integrated Overtemperature/Overcurrent Protection

Under-Voltage Lockout Feature

The EN function enables the output to be turned off,

while the electric charge at the output capacitor is

discharged via the internal auto-discharge resistance,

and as a result the VOUT pin quickly returns to the GND

level.

Chip Enable Input

Power-OK

Low Quiescent Current: 10µA

Low Output Noise: 15µV @ 100kHz Bandwidth

Operating Temperature Range: -40°C to +85°C

8-pin TDFN 2x2 Package

Furthermore a Bypass Pin is included to reduce noise.

The device features integrate short-circuit and over

current protection. Under-Voltage lockout prevents

erratic operation when the input voltage is slowly

decaying. Thermal Protection shuts down the device

when die temperature reaches 160°C. This is a useful

protection when the device is under sustained short

circuit conditions.

3 Applications

The AS1367 is ideal for cellular phones, cordless

phones, wireless communication equipment, portable

games, cameras, video recorders, portable audio-video

equipment and personal digital assistants.

The device is available in a 8-pin TDFN 2x2 package.
