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=65dB @ 120Hz; 55dB @ 1kHz
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
in a space saving TSOT-23-5, 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 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 28µVRMS with 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.
