600mA CMOS LDO REGULATOR WITH ENABLE AP2112

Data Sheet

General Description

The AP2112 is CMOS process low dropout linear regulator with enable function, the regulator delivers a guaranteed 600mA (min.) continuous load current.

The AP2112 provides 1.2V, 1.8V, 2.5V, 2.6V, 2.8V and 3.3V regulated output and 0.8V to 5V adjustable output, and provides excellent output accuracy ±1.5%, also provides an excellent load regulation, line regulation and excellent load transient performance due to very fast loop response. The AP2112 has built-in auto discharge function.

The regulator features low power consumption, and provides SOT-23-5, SOT-89-5, and SOIC-8 packages.
