Data Sheet
600mA CMOS LDO REGULATOR WITH ENABLE
AP2112
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 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.
