TPS70345-EP 具有加电定序的增强型产品双路输出低压降稳压器

The TPS70345 is designed to provide a complete power management solution for Texas Instruments 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 Texas Instruments DSP applications with power sequencing requirement. 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 low dropout voltage and dual outputs with power up sequence control, which is designed primarily for DSP applications. This device has a low noise output performance without using any added filter bypass capacitors and are designed to have a fast transient response and be stable with 47 µF low ESR capacitors
