General Description

FB/SENSE RESET EN GND TPS771xx DGK Package (TOP VIEW) 1 8 2 7 3 6 4 5 OUT OUT IN IN FB/SENSE PG EN GND TPS772xx DGK Package (TOP VIEW) 1 8 2 7 3 6 4 5 OUT OUT IN IN TPS77x33 DROPOUT VOLTAGE vs JUNCTION TEMPERATURE 300 The TPS771xx and TPS772xx are low-dropout 250 regulators with integrated power-on reset and VDO – Dropout Voltage – mV power good (PG) function respectively.

These 200 devices are capable of supplying 150 mA of output current with a dropout of 115 mV (TPS77133, TPS77233).

Quiescent current is 92 µA at full load 150 IO = 150 mA 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 TPS771xx features an integrated power-on reset, commonly used as a supply voltage supervisor (SVS) or reset output voltage. The RESET output of the TPS771xx 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 TPS771xx monitors the output voltage of.
