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.
