AAP2967
300mA Low-Noise Low-Dropout
Linear
Regulator
DESCRIPTION
The A AP2967 l ow-noise, low -dropout, li near
regulator o perates fro m a 2.5V t o 5.5V i nput a nd is
guaranteed to deliver 300mA.
The AAP2967 is st able w ith sm all 2.2µF ceram ic
capacitor. Its perform ance suits batt ery powered
applications beca use of it s shutdown m ode, low
quiescent current, and very low dropout voltage. The
low dropout voltage allows for more utilization of a
battery’s ava ilable e nergy by opera ting closer t o i ts
end-of-life voltage.
The AAP2967 is av ailable in 1.5V,1.8V,2.5V, 2.8V,
3V ,3.3V and Adjustable versions.
