3 Description

The TPS715A low-dropout (LDO) linear voltage

regulator is a low quiescent current device that

offers the benefits of a wide input voltage range

and low-power operation in miniaturized packaging.

Thus, the TPS715A is designed for battery-powered

applications and as a power-management attachment

to low-power microcontrollers.

The TPS715A is available in both fixed and

adjustable versions. For more flexibility or higher

output voltages, the adjustable version uses external

feedback resistors to set the output voltage from

1.205 V to 15 V. The TPS715A LDOs support a low

dropout of 650 mV (typ) at 80 mA of load current.

The low quiescent current (3.2 μA typically) is stable

over the entire range of output load current (0 mA

to 80 mA). The TPS715A (new chip) also features

an internal soft-start to lower the inrush current. The

built-in overcurrent limit helps protect the regulator in

the event of a load short or fault.

The TPS715A is available in a 3-mm × 3-mm package

for use in high power dissipation applications and a

small 2-mm × 2-mm package for hand-held and ultraportable

applications. The 3-mm × 3-mm package is

also available as a non-magnetic package for medical

imaging applications.
