The EUP7961 is a 1A low-dropout linear regulator that

provides a low voltage, high current output with a

minimum of external components. It offers high

precision, ultra-low dropout, and low ground current.

The EUP7961 operates from an input of 2.5V to 5.5V.

This regulator uses small, 1µF ceramic input capacitors

and 4.7µF ceramic output capacitors to deliver 1A

output current. High bandwidth provides excellent

transient response. It is designed to drive digital

circuits requiring low voltage at 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 nominal value.

It is available in fixed output voltages of 1.5V, 1.8V,

2.5V, 3.3V and as an adjustable device with a 0.8V

reference voltage. The adjustable output voltage can be

set from 0.8V to 4.5V.

APPLICATIONS

LDO Linear Regulator for Low-Voltage Digital IC
