AP2112 Datasheet, PDF (1/19 Pages) BCD Semiconductor Manufacturing Limited – 600mA CMOS LDO REGULATOR WITH ENABLE

Preliminary Datasheet
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 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.
