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.DPaLtaDShs,eeDt4SUP.cso, mmicrocontrollers, 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.
