G9614
Low-Dropout, 500mA Linear Regulator with POK
Features
General Description
500mA Output Current, with Foldback Current
The G9614 are low-dropout, linear regulator with
PowerGood function. Shutdown turns off whole IC.
Other features include foldback current limiting and
thermal overload protection.
Limiting
High Ripple Rejection
±2% Output Accuracy
±2% POK Threshold Accuracy
Externally Programmable POK Time Delay
Generator
The POK function in G9614 detect VOUT level, keep-
ing it asserted for time delay determined by external
capacitor. The POK output is active low open-drain
output. The detection threshold are 90% of the regu-
lator output voltage.
Internal 500mA P-Channel Pass Transistor
300µA quiescent Current
Thermal Overload Protection
