G916

300mA High PSRR, Low Noise, LDO Regulators

Features

General Description

Low, 90µA No-Load Supply Current

Guaranteed 300mA Output Current

Dropout Voltage is 200mV @ 150mA Load

PSRR=70dB

Over-Temperature Protection and Short-Circuit

Protection

The G916 series is a low supply current, high PSRR,

low noise, and low dropout linear regulator that comes

space saving TSOT-23-5, SOT-23-5

SC-70-5(SOT-353) package. The supply current at

no-load is 90µA. In the shutdown mode, the maximum

supply current is less than 1µA. Operating voltage

range is from 2.5V to 6.0V. The over-current protection

limit is set at 550mA typical. An over- temperature

protection circuit is built-in in the Device to prevent

thermal overload. These power saving features make

the G916 series ideal for use in the battery-powered

applications such as notebook computers, cellular

phones, and PDA’s.

Fixed Mode: 1.20V~5.00V (G916-XXX)

Adjustable Mode: from 1.25V to 5.50V (G916)

Max. Supply Current in Shutdown Mode < 1µA

Low Output Noise at 28µV_RMSwith bypass Ca-

pacitor

Stable with low cost ceramic capacitors

The G916 has two modes of operation. When the SET

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

3.3V. There is no external component needed. When an

output other than the preset value is needed, two ex-

ternal resistors should be used as a voltage divider. The

output voltage is then adjusted by the resistor ratio.

G916-XXX is with fixed-mode output. The output voltage

range is from 1.2V to 5.0V.
