High Input Voltage, Low Quiescent Current
The WL2852K series is a high accuracy, high input
voltage low quiescent current, high speed, and low
dropout Liner regulator with high ripple rejection. The
device is manufactured with Bi-CMOS process.
The WL2852K offers over-current limit and over
temperature protection to ensure the device working in
