description
The TPS767D3xx family of dual voltage regulators offers fast transient response, low dropout voltages and dual
outputs in a compact package and incorporating stability with 10-μF 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 1 A. Dual active-low
reset signals allow resetting of core-logic and I/O separately.
