The TPS715AxxA low-dropout (LDO) voltage regulators from Texas Instruments offer the benefits of high input voltage, low-dropout voltage, low-power operation, and miniaturised packaging. The devices, which operate over an input range of 2,5 V to 24 V, are said to be stable with any capacitor (>0,47 μF). The high maximum input voltage combined with good power dissipation capability makes this IC particularly well suited to industrial and automotive applications.
A PMOS pass element behaves 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).
Available in 3,3 V and adjustable, the regulators are specified over -40 to 125°C, and come in 3 x 3 mm SON package.
