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 and 3.3V regulated output,
and provides excellent output accuracy 1.5%, 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 regulator features low power consumption, and
provides SOIC-8, PSOP-8 and SOT-223 packages.
