General Description

The AP2114 is CMOS process low dropout linear

regulator with enable function, the regulator delivers

a guaranteed 1A (Min.) continuous load current.

The AP2114 features low power consumption.

The AP2114 is available in 1.2V, 1.8V, 2.5V and

3.3V regulator output, and available in excellent

output accuracy 1.5%, it is also available in an

excellent load regulation and line regulation

performance.

The AP2114 is available in standard packages of

SOT-223, TO-252-2 (1), TO-252-2 (3), TO-263-3,

SOIC-8 and PSOP-8.
