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.
