EUP7982 300mA Low-Noise Ultra Low-Dropout
CMOS Regulator with Fault Indicator
FEATURE DESCRIPTION
The EUP7982 low-noise, low-dropout, linear regulator operates from a 2.5V to 5.5V input and is guaranteed to deliver 300mA. The EUP7982 is stable with small 2.2µF ceramic capacitor. Its performance suits battery powered applications because of its shutdown mode (60 nA www.DataSheet4U.com typ), low quiescent current (110µA typ), and LDO
voltage (140mV typ). The low dropout
voltage allows for more utilization of a battery’s available energy by operating closer to its end-of-life
voltage. An output fault-detection circuit indicates loss of regulation. The EUP7982 is available in MSOP package with 1.8V, 2.5v, 2.8V, 3V, 3.3V, and adjustable versions. z z z z z z z z z z z z z z z z 2.5V to 5.5V Input Range 300mA Guaranteed Output Current 60dB PSRR at 1kHz 50µV RMS Output
