3 Description

The TPS715A-NM low-dropout (LDO) voltage

regulators offer the benefits of high input voltage, lowdropout

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-NM 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 non-magnetic package for medical

imaging applications.
