EUP7966

EUP7966 2A Low-Dropout Regulator with Enable DESCRIPTION The EUP7966 is a high current, fast response voltage regulator designed for use in applications requiring very low input voltage and very low dropout voltage at up to 2 amps. It operates from two input voltages : VBIAS provides 5V voltage to drive the gate of the N-MOS power transistor, while VIN is the input voltage which supplies power to the load. The use of an external bias rail allows the part to operate from ultra low VIN voltage. The EUP7966 features ultra low dropout, ideal for applications where VOUT is very close to VIN. Additionally, the EUP7966 has an enable pin to further reduce power dissipation while shutdown. The EUP7966 provides excellent regulation over variations in line, load and temperature. The EUP7966 provides a power OK signal to indicate if the voltage level of VOUT reaches 92% of its rating value. The EUP7966 is available in the power SOP-8 (FD) package. It is available with 1.2V, 1.5V, 1.8V and 2.5V internally preset outputs, that are also be able to programmed as low as 0.8V with ADJ pin configured with external resistors.
