3 Description
The TLV741P low-dropout (LDO) linear regulator is a
low quiescent current LDO with excellent line and
load transient performance and is designed for
power-sensitive applications. This device provides a
typical accuracy of 1%.
The TLV741P device is designed to be stable with a
small, 1-µF output capacitor.
The TLV741P device provides inrush current control
during device power up and enabling. The TLV741P
device limits the input current to the defined current
limit to avoid large currents from flowing from the
input power source. This functionality is especially
important in battery-operated devices.
The TLV741P is available in a standard DBV (SOT-
23) package. The TLV741P provides an active
pulldown circuit to quickly discharge output loads.
