1 / 13 page  EUP7963 DS7963 Ver 1.4 Oct. 2007 1 3A Ultra Low-Dropout Linear Regulator DESCRIPTION The EUP7963 is a 3A 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 EUP7963 operates from an input of 2.5V to 5.5V. This regulator uses small, 4.7µF ceramic input capacitors and 10µF ceramic output capacitors to deliver 3A 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. Typical Application Circuit FEATURES 3A Guaranteed Output Current 750mV Dropout Voltage at 3A Output Stable with Ceramic Capacitors ±1.8% Output Voltage Accuracy 1mA Low-Ground Pin Current 0.1µA Quiescent Current in Shutdown Mode Excellent Line and Load Regulation Thermal Shutdown and Current Limit Protection Error Flag Indication Available in To-263, and To-220 Packages RoHS Compliant and 100% Lead (Pb)-Free APPLICATIONS LDO Linear Regulator for Low-Voltage Digital IC PC Add-In Cards High Efficiency Linear Power Supplies Post Regulator Figure1. |
