3 Description

The TPS715A low-dropout (LDO) voltage regulators

offer the benefits of high input voltage, low-dropout

voltage, low-power operation, and miniaturized

packaging. The devices operate over an input range

of 2.5 V to 24 V and are stable with any capacitor (≥

0.47 μF). The high maximum input voltage combined

with excellent power dissipation capability makes this

device particularly well-suited to industrial and

automotive applications.

A PMOS pass element functions as a low-value

resistor. The low dropout voltage, typically 670 mV at

80 mA of load current, is directly proportional to the

load current. The low quiescent current (3.2 μA

typically) is nearly constant over the entire range of

output load current (0 mA to 80 mA).

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

package ideal for high power dissipation and a small

2-mm × 2-mm package ideal for handheld and ultraportable

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

also available as a no
