EUP7961  
1A Ultra Low-Dropout Linear Regulator  
FEATURES  
DESCRIPTION  
The EUP7961 is a 1A low-dropout linear regulator that  
provides a low voltage, high current output with  
minimum external components. The features include  
precision output voltage, ultra-low dropout voltage,  
and low ground current.  
The EUP7961 operates from an input of 2.5V to 5.5V.  
This regulator uses a 1µF ceramic input capacitors and  
a 4.7µF ceramic output capacitor to deliver 1A output  
current. High bandwidth provides excellent transient  
response. It is designed to power digital circuits  
requiring low voltage with high currents (i.e., PLDs,  
DSPs, microcontrollers, etc.).  
Other features include thermal and current limit  
protection, a logic-control shutdown mode and an error  
flag output that goes low when the output voltage  
drops 10% below the nominal value.  
It is available in fixed output voltages of 1.5V, 1.8V,  
2.5V, 3.3V or adjustable output voltage with a 0.8V  
feedback voltage. The adjustable output voltage can be  
set from 0.8V to 4.5V.
