Data Sheet
600mA CMOS LDO REGULATOR WITH ENABLE
AP2111
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 1.8V, 2.5V, 3.3V and
4.8V regulated 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 and
SOT-223 packages.
