Texas Instruments TPS70748PWP

Description
The TPS707xx family of voltage regulators provides a complete power management solution for TMS320 DSP family, processor power, ASIC, FPGA, and digital applications requiring dual output voltage regulators. The programmable sequencing function makes the TPS707xx family ideal for TMS320 DSP applications with power sequencing requirements. Features such as accuracy, fast transient response, SVS supervisory circuit, manual reset inputs, and an enable function provide a complete system solution.
These devices offer very low dropout voltage and dual outputs with power-up sequence control, primarily designed for DSP applications. They have extremely low noise output performance without added filter bypass capacitors and are designed for a fast transient response and stability with 10uF low ESR capacitors.
The TPS707xx family includes fixed 3.3V/2.5V, 3.3V/1.8V, 3.3V/1.5V, 3.3V/1.2V, and adjustable/adjustable voltage options. Regulator 1 supports up to 250mA, while regulator 2 supports up to 125mA. Separate voltage inputs allow for source power configuration.
