EUP7961

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.
