600mA CMOS LDO REGULATOR WITH ENABLE AP2111

Dec. 2012 Rev. 1. 7 BCD Semiconductor Manufacturing Limited

General Description

The AP2111 is CMOS process low dropout linear

regulator with enable function, the regulator delivers

a guaranteed 600mA (Min) continuous load current.

The AP2111 provides 1.2V, 1.5V, 1.8V, 2.5V, 3.3V,

4.8V regulated output and 0.8V to 5V adjustable

output, and provides excellent output accuracy 1.5%,

it is also provides a excellent load regulation, line

regulation and excellent load transient performance

due to very fast loop response. The AP2111 has

built-in auto discharge function.

The AP2111 features low power consumption.

The AP2111 is available in SOIC-8, PSOP-8

SOT-223 and SOT-23-5 packages.
