General Description
VO Follows 1.6 Times of VSET
150mV Dropout @ 0.5A
Over Current and Over Temperature Protection
Enable Pin
10µA Quiescent Current in Shutdown
Soft Start to Decrease Inrush Current
Power SOP-8 and TDFN3X3-8 Package
The G996 is a high performance positive voltage
regulator designed for use in applications requiring
very low dropout voltage at up to 0.5 Amps. The G996
VO output voltage follows the 1.6 times of VSET voltage until it reaches VIN voltage. The VSET voltage
must be larger than 1V to guarantee VO 1.6 times of
VSET. An enable pin further reduces power dissipation while shut down. The G996 provides excellent
regulation over variations in line, load and temperature.
