EUP7962
2A Ultra Low-Dropout Linear Regulator
DESCRIPTION
The EUP7962 is a 2A 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 EUP7962 operates from an input of 2.5V to 5.5V.
This regulator uses small, 2.2µF ceramic input
capacitors and 10µF ceramic output capacitors to
deliver 2A 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.
