3 Description

The TPS715A-NM 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-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 ultra-portable applications. The 3-mm × 3-mm package is also available as a non-magnetic package for medical imaging applications.
