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.
