The TPS714 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 TPS714 is designed for battery-powered applications and as a power-management attachment to low-power microcontrollers.

The TPS714 is available in both fixed and adjustable versions. For more flexibility or higher output voltages, the adjustable version uses external feedback resistors to set the output voltage from 1.205 V to 8.8 V. The TPS714 LDO supports a low dropout of 650 mV (typ) at 80 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 80 mA). The TPS714 (new chip only) 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 TPS714 is available in a 2-mm × 2-mm package for use in high power dissipation applications and the SC70-5 package is designed for hand-held and ultra-portable applications.
