AAP2967
300mA Low-Noise Low-Dropout
Linear Regulator
DESCRIPTION
The AAP2967 low-noise, low-dropout, linear
regulator operates from a 2.5V to 5.5V input and is
guaranteed to deliver 300mA.
The AAP2967 is stable with small 2.2µF ceramic
capacitor. Its performance suits battery powered
applications because of its shutdown mode, low
quiescent current, and very low dropout voltage. The
low dropout voltage allows for more utilization of a
battery’s available energy by operating closer to its
end-of-life voltage.
The AAP2967 is available in 1.5V,1.8V,2.5V, 2.8V,
3V ,3.3V and Adjustable versions.
