3 Description

The TPS720-Q1 family of dual-rail, low-dropout linear

regulators (LDOs) offers outstanding ac performance

(PSRR, load and line transient response) and

consume a very low quiescent current of 38

μA.

LDO draws very low current (on the order of the LDO

quiescent current) and can be connected to any

power supply that is equal to or greater than 1.4 V

above the output voltage. The main power path is

efficiency of the solution in many power-sensitive

high-efficiency, dc-dc, step-down regulator.

The TPS720-Q1 supports a novel feature where the

output of the LDO regulates under light loads when

the IN pin is left floating. The light-load drive current

feature

is

particularly

useful

in

power-saving

applications where the dc-dc converter connected to

the IN pin is disabled but the LDO is still required to

regulate the voltage to a light load.

The TPS720-Q1 is stable with ceramic capacitors and

uses an advanced BICMOS fabrication process that

yields a dropout of 110 mV at a 350-mA output load.

The TPS720-Q1 has the unique feature of providing a

output capacitor of 2.2

μF.

The TPS720-Q1 uses a precision voltage reference

and feedback loop to achieve overall accuracy of 2%

over load, line, process, and temperature extremes.

The TPS720-Q1 is available in a 6-pin WSON

package. This family of devices is fully specified over
