G923

300mA High PSRR LDO Regulators

Features

General Description

Low, 90µA No-Load Supply Current

The G923 is a low supply current, high PSRR, and low

dropout linear regulator that comes in a space saving

SOT-23-5 package. The supply current at no-load is

90µA. In the shutdown mode, the maximum supply

current is less than 1µA. Operating voltage range of

the G923 is from 2.50V to 5.50V. The over-current

protection limit is set at 550mA typical. An over- tem-

perature protection circuit is built-in in the G923 to

prevent thermal overload. These power saving fea-

tures make the G923 ideal for use in the bat-

tery-powered applications such as notebook com-

puters, cellular phones, and PDA’s.

Guaranteed 300mA Output Current

Dropout Voltage is 200mV @ 150mA Load

PSRR=65dB @ 120Hz

Over-Temperature Protection and Short-Circuit

Protection

Two Modes of Operation ----

Fixed Mode: 1.50V~5.00V

Adjustable Mode: from 1.25V to 5.50V

Max. Supply Current in Shutdown Mode < 1µA

Low Output Noise at 224µV_RMS

Stable with low cost ceramic capacitors

The G923 has two modes of operation. When the SET

pin is connected to ground, its output is a pre-set value:

1.50V~5.00V. There is no external component needed

to decide the output voltage. When an output other

than the preset value is needed, two external resistors

should be used as a voltage divider. The output volt-

age is then decided by the resistor ratio. The G923

comes in a space saving SOT-23-5 package.
