TPS715-Q1 (ACTIVE) 50-mA, 24-V, 3.2-μA Supply Current, Low-Dropout Linear Regulators in SC70 Package

 

Description

The TPS715xx-Q1 low-dropout (LDO) voltage regulators offer the benefits of high input voltage, LDO voltage, low-power operation, and miniaturized packaging. The devices, which operate over an input range of 2.5 V to 24 V, are stable with any capacitor (>0.47 µF). The LDO voltage and low quiescent current allow operations at extremely low power levels. Therefore, the devices are ideal for powering battery-management ICs. Specifically, since the devices are enabled as soon as the applied voltage reaches the minimum input voltage, the output is quickly available to power continuously operating battery-charging ICs.

The usual PNP pass transistor has been replaced by a PMOS pass element. Because the PMOS pass element behaves as a low-value resistor, the LDO voltage, typically 415 mV at 50 mA of load current, is directly proportional to the load current. The low quiescent current (3.2  μA typical) is stable over the entire range of output load current (0 mA to 50 mA).

For all available packages, see the orderable addendum at the end of the data sheet.Contact Texas Instruments for other voltage options between 1.25 V and 5.85 V.
