Preliminary Datasheet
1A LOW NOISE CMOS LDO REGULATOR WITH ENABLE
General Description
The AP2115 is CMOS process low dropout linear
regulator with enable function, the regulator delivers
a guaranteed 1A (min.) continuous load current.
The AP2115 features low power consumption.
•
The AP2115 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 AP2115 is available in standard packages of
SOIC-8 and SOT-89-5.
