Data Sheet
600mA CMOS LDO REGULATOR WITH ENABLE
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, 4.8V
regulated output and 0.8V to 5V adjustable 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
SOT-223 and SOT-23-5 packages.
