General Description

These devices are designed to have a fast transient response and be stable with 10-µF low ESR capacitors.

This combination provides high performance at a reasonable cost.

Key Features

  • a sleep mode; applying a TTL high signal to the enable (EN) input shuts down the regulator, reducing the quiescent current to 1 µA at TJ = 25°C. The RESET output of the TPS767xx initiates a reset in microcomputer and microprocessor systems in the event of an undervoltage condition. An internal comparator in the TPS767xx monitors the output voltage of the regulator to detect an undervoltage condition on the regulated output voltage. The TPS767xx is offered in 1.5-V, 1.8-V, 2.5-V, 2.7-V, 2.8-V,.
