DESCRIPTION

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.
