DESCRIPTION
TPS701xx family devices are designed to provide a complete power management solution for the TMS320M DSP family, processor power, ASIC, FPGA, and digital applications where dual output voltage regulators are required. Easy programmability of the sequencing function makes the TPS701xx family ideal for any TMS320 DSP applications with power sequencing requirements. Differentiated features, such as accuracy, fast transient response, SVS supervisory circuit, manual reset inputs, and an enable function, provide a complete system solution.
The TPS701xx family of voltage regulators offer very low dropout voltage and dual outputs with power-up sequence control, which is designed primarily for DSP applications. These devices have extremely low noise output performance without using any added filter bypass capacitors and are designed to have afast transient response and be stable with 10uF low ESR capacitors.These devices have fixed 3.3V/2.5V,3.3V/1.8V,3.3V/1.5V,3.3V/1.2V, and adjustable/adjustablevoltage options. Regulator 1 can support up to 500mA, and requlator 2 can support up to 250mA.Separate voltage inputs allow the designer to configure the source power.
