3 Description

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

The TPS715 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 1.205 V to 15 V. The TPS715 LDOs support 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 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.
