300mA Low-Noise Low-Dropout Linear Regulator


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 1.2V,1.5V,1.8V,2.5V, 2.8V, 3V ,3.3V and Adjustable versions.
