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.
