The TPS740xx is a wide bandwidth, very low-dropout, 1.5-A voltage regulator ideal for powering microprocessors.

The TPS740xx uses a bias input supply to allow very low voltage of a main input supply. The main input supply operates from 1.2 V to 6.0 V and the bias input supply requires between 3.0 V to 6.0 V for proper operation. The TPS740xx offers adjustable output voltages down to 0.9 V.

The TPS740xx requires a minimum of output capacitance. A small 2.2-µF ceramic capacitor is enough for its stability.

The TPS740xx is available in an 8-pin power MSOP package and a 5-pin Jr S-PAK. Its operating temparature range is –40°C to +125°C.
