TPS70358M 双路输出低压降 (LDO) 稳压器
The TPS70358 is 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 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 TPS70358 regulator offers very low dropout voltage and dual outputs with power up sequence control, which is designed primarily for DSP applications. These devices have 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
