AP2112 LDO Regulator Introduction

TheAP2112is an efficient linear voltage regulator with ultra-low noise output, very low dropout voltage (400 mV), and very low ground current. The input voltage of the Regulator can be between 2.5V to 6V. AP2112 is especially designed for hand-held, battery-powered devices, the AP2112 includes a CMOS compatible enable/shutdown control input. When shutting down, power consumption drops nearly to zero.

AP3112 is generally used in Laptop, Notebook, Portable DVD, LCD Monitor and Palmtop Computers, and other battery-Powered Equipment’s.

How to use the AP2112 Regulator

AP2112 low dropout regulatorcomes in 5 and 8-pin package in which the enable pin can be used turn on or off the regulator, this helps the designers to turn off the regulator and prevent battery usage when not in use.Supply the input voltage to the V-in pin and we get the regulated 3.3V at the output pin. The input and output capacitors are used for ripple filtering. A sample application circuit from theAP2112 datasheetis shown below.
