LDO LINEAR REGULATORS

Check for Samples: TPS715Axx

FEATURES

DESCRIPTION

The TPS715Axx low-dropout (LDO) voltage

• 24V Maximum Input Voltage

regulators offer the benefits of high input voltage, low-

• Low 3.2μA Quiescent Current at 80mA

dropout voltage, low-power operation, and

• Stable With Any Capacitor (> 0.47μF)

miniaturized packaging. The devices, which operate

over an input range of 2.5V to 24V, are stable with

• 80mA Specified Current

any capacitor (≥ 0.47μF). The high maximum input

• Available in Fixed and Adjustable (1.2V to 15V)

voltage combined with excellent power dissipation

Versions

capability makes this part particularly well-suited to

industrial and automotive applications.

• 3mm × 3mm and 2mm x 2mm SON Packages

A PMOS pass element behaves as a low-value

• –40°C to +125°C Specified Junction

resistor. The low dropout voltage, typically 670mV at

80mA of load current, is directly proportional to the

typically) is nearly constant over the entire range of

TPS715xx

output load current (0mA to 80mA).

The TPS715Axx is available in 3mm x 3mm package
