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