F. 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, 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.
