EUP7967A-300mA,低噪声,低压差线性稳压器  DataSheet
概述
EUP7967A是一款低噪声、低压差线性稳压器，在2.5V至5.5V的输入范围内工作，能提供300mA的电流。
EUP7967A外接小型的2.2μF陶瓷电容就能稳定地工作，由于它具有使能关断模式、低静态电流和极低压差的特性，因此非常适合应用于电池供电设备。低压差特性允许器件在电池很低的极限电压时仍能继续工作，这大大增加了电池能量的使用效率。
EUP7967A提供了1.2V、1.5V、1.8V、2.5V、2.8V、3V和3.3V输出电压版本。

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