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 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...
