General Description

The TPS773xx and TPS774xx are low-dropout regulators with integrated power-on reset and power good (PG) function respectively.

These devices are capable of supplying 250 mA of output current with a dropout of 200 mV (TPS77333, TPS77433).

Quiescent current is 92 µA at full load dropping down to 1 µA when device is disabled.

Key Features

  • a sleep mode; applying a TTL high signal to EN (enable) shuts down the regulator, reducing the quiescent current to less than 1 µA at TJ = 25°C. The TPS773xx features an integrated power-on reset, commonly used as a supply voltage supervisor (SVS), or reset output voltage. The RESET output of the TPS773xx initiates a reset in DSP, microcomputer or microprocessor systems at power up and in the event of an undervoltage condition. An internal comparator in the TPS773xx monitors the output voltage o.
