EUP7961 1A Ultra Low-Dropout Linear Regulator
DESCRIPTION
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., www.DataSheet4U.com 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.
