Preliminary Datasheet
1A LOW NOISE CMOS LDO REGULATOR WITH ENABLE AP2114
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.
