The TPS746 is an adjustable 1-A low-dropout (LDO) regulator with power-good functionality. This device is available in a small, 6-pin, 2-mm × 2-mm WSON package and consumes very low quiescent current and provides fast line and load transient performance. The TPS746 features an ultra-low dropout of 225 mV at 1 A that can help improve the power efficiency of the system.

The TPS746 is optimized for a wide variety of applications by supporting an input voltage range from 1.5 V to 6.0 V and an externally adjustable output range of 0.55 V to 5.5 V. The low output voltage enables this LDO to power the modern microcontrollers with lower core voltages. Additionally, the TPS746 has a low I_Q with enable functionality to minimize standby power. This device features an internal soft-start to lower the inrush current, which provides a controlled voltage to the load and minimizes the input voltage drop during start up.

The TPS746 has a power-good (PG) output that monitors the voltage at the feedback pin to indicate the status of the output voltage. The EN input and PG output can be used for sequencing multiple power sources in the system.

The TPS746 is stable with small ceramic output capacitors, allowing for a small overall solution size. A precision band-gap and error amplifier provides a high accuracy of 0.7% max at 25ºC and 1% max over temperature (85ºC). This device includes integrated thermal shutdown, current limit, and undervoltage lockout (UVLO) features. The TPS746 has an internal foldback current limit that helps reduce the thermal dissipation during short-circuit events.
