The TPS715-Q1 low-dropout (LDO) linear voltage regulator is a low quiescent current device that offers the benefits of a wide input voltage range and low-power operation in miniaturized packaging. Thus, the TPS715-Q1 is designed for battery-powered applications and as a power-management attachment to low-power microcontrollers.

The TPS715-Q1 is available in both fixed and adjustable versions. For more flexibility or higher output voltages, the adjustable version uses feedback resistors to set the output voltage from 1.2 V to 15 V. The TPS715-Q1 LDO supports a low dropout of typically 415 mV at 50 mA of load current. The low quiescent current (3.2 µA typically) is stable over the entire range of output load current (0 mA to 50 mA). The TPS715-Q1 also features an internal soft-start to lower the inrush current. The built-in overcurrent limit helps protect the regulator in the event of a load short or fault.

The TPS715-Q1 is available in a 2.00 mm × 1.25 mm, 5-pin SC-70 (DCK) package for fixed and adjustable outputs.
