与POWER UP测序SPLIT电压DSP系统双输出低压差稳压器 DUAL-OUTPUT LOW-DROPOUT VOLTAGE REGULATORS WITH POWER UP SEQUENCING FOR SPLIT VOLTAGE DSP SYSTEMS

The is a dual-output low-dropout LDO Voltage Regulator designed to provide a complete power management solution for many applications where dual output voltage regulator is required. Easy programmability of the sequencing function makes this family ideal for any DSP application with power sequencing requirements. Differentiated features such as accuracy, fast transient response, SVS supervisory circuit, manual reset inputs and enable function, provide a complete system solution. This 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. Because the PMOS pass element behaves as a low-value resistor, the dropout voltage is very low and is directly proportional to the output current.
