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, 2.8V 
and 3.3V regulated output and 0.8V to 5V adjustable 
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.
