1.5-A, Low-Voltage LDO Regulator with Dual Input Voltages

FEATURES

DESCRIPTION

The TPS740xx is a wide bandwidth, very low-dropout,

1.5-A voltage regulator ideal for powering

microprocessors.

•

Small Consumption Current: 3 mA Maximum

Input Voltage Range:

•

–

V_IN: 1.2 V to 6.0 V

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.

V_BIAS: 2.9 V to 6.0 V

•

Stable with Any Output Capacitance: ≥ 2.2 μF

±1% Initial Accuracy

Maximum Dropout Voltage (V_IN– V_OUT):

300 mV Over Temperature

The TPS740xx requires

a minimum of output

•

Adjustable Output Voltage: Down to 0.9 V

Ultra-Fast Transient Response

capacitance. A small 2.2-μF ceramic capacitor is

enough for its stability.

Excellent Line and Load Regulation

Logic-Controlled Shutdown Option

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.
