Texas Instruments TLV740P Low-Dropout (LDO) Linear Regulator

Texas Instruments TLV740P Low-Dropout (LDO) Linear Regulator is a low quiescent current LDO with excellent line and load transient performance designed for power-sensitive applications. This device provides a typical accuracy of 1%. The TLV740P also provides inrush current control during device power up and enabling. The Texas Instruments TLV740P 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 TLV740P also provides an active pulldown circuit to quickly discharge output loads.
