EUP7967A
300mA Low-Noise Low-Dropout
Linear Regulator
DESCRIPTION
The EUP7967A low-noise, low-dropout, linear
regulator operates from a 2.5V to 5.5V input and is
guaranteed to deliver 300mA.
The EUP7967A 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 EUP7967A is available in 1.5V,1.8V,2.5V, 2.8V,
3V ,3.3V and Adjustable versions.
