LV5710GP
Bi-CMOS LSI
Power Supply for Charge Pump
for Camera Sensor
http://onsemi.com
Overview
The LV5710GP is power supply for charge pump for camera sensor.
Functions
Regulating the 5V input by boosting it three-fold with the charge pump
to the specified voltage.
Output voltage variable with external resistor.
Soft start function incorporated, which reduces the rush current at start
of charge pump.
Timer-latch type short-circuit protective function incorporated.
