600mA CMOS LDO REGULATOR WITH ENABLE AP2112

Mar. 2013 Rev. 2. 0 BCD Semiconductor Manufacturing Limited

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.
