3 Description
The TLV743P low-dropout linear regulator (LDO) is
an ultra-small, low quiescent current LDO that
sources 300 mA with good line and load transient
performance. The device provides a typical accuracy
of 1%.
The TLV743P is designed to be stable with a small
output capacitor with a value of 1 μF. The TLV743P
device provides foldback current control during device
power up and enabling. This functionality is especially
important in battery-operated devices.
The TLV743P provides an active pulldown circuit to
quickly discharge output loads when the device is
disabled.
The TLV743P is available in standard DBV (SOT-23)
and DQN (X2SON) packages.
