Overview

The AP2125K-X.XTRG1(MS) series is a family of low dropout (LDO) regulators featuring a wide input voltage range of 1.2V to 5.5V, low dropout voltage, low power consumption, and compact packaging. The AP2125K-X.XTRG1(MS) offers an ultra-low quiescent current of 2uA, making it particularly well-suited for battery-powered devices and long-term standby applications. It helps reduce system standby power consumption, effectively extending standby time and battery life. The AP2125K-X.XTRG1(MS) is available in a version with an EN enable pin. Pulling the EN pin low enters shutdown mode, in which the quiescent current drops to as low as 100nA (typical). The AP2125K-X.XTRG1(MS) series supports ceramic output capacitors and operates stably across the full 1.2V to 5.5V input voltage range and the entire output load current range of 0mA to 300mA.

Applications

Handheld, battery-powered devices
