TLV743P Low-Dropout Linear Regulator (LDO)

Texas Instruments TLV743P Low-Dropout Linear Regulator (LDO) is an ultra-small, low quiescent current LDO that sources 300mA 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 of 1µF. This device provides foldback current control during device power-up and enabling. This functionality is especially important in battery-operated devices. The Texas Instruments TLV743P provides an active pull-down circuit to discharge output loads when the device is disabled quickly.
