The TPS767D3xx family of dual voltage regulators offers fast transientresponse, low dropout voltages and dual outputs in a compact package and incorporating stability with 10µF low ESR output capacitors.

The TPS767D3xx family of dual voltage regulators is designed primarily for DSP applications. These devices can be used in any mixed-output voltage application, with each regulator supporting up to 1A. Dual active-low reset signals allow resetting of core-logic and I/O separately.

Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (350mV typically at an output current of 1A for the TPS767D325) and is directly proportional to the output current. Additionally, since the PMOS pass element is a voltage-driven device, the quiescent current is very low and independent of output loading (typically 85µA over the full range of output current, 0mA to 1A). These two key specifications yield a significant improvement in operating life for battery-powered systems. This LDO family also features a sleep mode; applying a TTL high signal to EN (enable) shuts down the regulator, reducing the quiescent current to 1µA at T_J = +25°C.

The RESET output of the TPS767D3xx initiates a reset in microcomputer and microprocessor systems in the event of an undervoltage condition. An internal comparator in the TPS767D3xx monitors the output voltage of the regulator to detect an undervoltage condition on the regulated output voltage.

The TPS767D3xx is offered in 1.8V, 2.5V, and 3.3V fixed-voltage versions and in an adjustable version (programmable over the range of 1.5V to 5.5V). Output voltage tolerance is specified as a maximum of 2% over line, load, and temperature ranges. The TPS767D3xx family is available in a 28-pin PWP TSSOP package. They operate over a junction temperature range of -40°C to +125°C.
