EUP7182

EUP7182 50mA Low-Noise Ultra Low-Dropout CMOS Regulator with Fault Indicator DESCRIPTION The EUP7182 low-noise, low-dropout, linear regulator operates from a 2.5V to 5.5V input and is guaranteed to deliver 50mA. The EUP7182 is stable with small 1µF ceramic capacitor. Its performance suits battery powered applications because of its shutdown mode (60 nA typ), low quiescent current (110µA typ), and LDO voltage (110mV 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 EUP7182 is available in SOT23-6 package with 1.8V, 2.5v, 2.8V, 3V and 3.3V versions.
