Preliminary Datasheet
600mA CMOS LDO REGULATOR WITH ENABLE
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 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.
