FEATURE  
DESCRIPTION

2.5V to 5.5V Input Range  
The EUP7982 low-noise, low-dropout, linear  
regulator operates from a 2.5V to 5.5V input and is  
guaranteed to deliver 300mA.  
300mA Guaranteed Output Current  
60dB PSRR at 1kHz  
50µV RMS Output Voltage Noise (10Hz to  
100kHz)  
The EUP7982 is stable with small 2.2µF ceramic  
capacitor. Its performance suits battery powered  
applications because of its shutdown mode (60 nA  
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.
