AP7168数据手册集成电路（IC）的线性+开关稳压器规格书PDF

描述 Description

The AP7168 is a 1.2A, adjustable output voltage, ultra-low
dropout linear regulator. The device includes pass element, error
amplifier, band-gap reference, current limit and thermal shutdown
circuitry. The device is turned on when EN pin is set to logic high
level. A Power-OK (POK) output is available for power sequence
control.
The characteristics of the low dropout voltage and low quiescent
current make it suitable for low to medium power applications, for
example, laptop computers, audio and video applications, and
battery powered devices. The typical quiescent current is
approximately 125μA.
Built-in current-limit and thermal-shutdown functions prevent
IC from damage in fault conditions. The AP7168 is available in
SO-8EP package.
