The TPS70345PWP is a Dual-output LDO Voltage Regulator designed to provide a complete power management solution for TI DSP, processor power, ASIC, FPGA and digital applications where dual output voltage regulators are required. Easy programmability of the sequencing function makes this family ideal for any TI DSP application with power sequencing requirements. Differentiated features, such as accuracy, fast transient response, SVS supervisory circuit (power-on reset), manual reset inputs and enable function provide a complete system solution. The TPS70345 voltage regulator offers very low dropout voltage and dual outputs with power up sequence control, designed primarily for DSP applications. This device has low noise output performance without using any added filter bypass capacitors and is designed to have a fast transient response and be stable with 47μF low ESR capacitors. Separate voltage inputs allow the designer to configure the source power.
