Dual-Output LDO Voltage Regulators

TPS701xx family devices are designed to provide a complete Power Management solution for the TMS320? 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 a fast transient response and be stable with 10F 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/adjustable voltage options. Regulator 1 CAN support up to 500mA, and Regulator 2 CAN support up to 250mA. Separate voltage inputs allow the designer to configure the source power.
Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 170mV on Regulator 1) and is directly proportional to the output current. Additionally, since the PMOS pass element is a voltage-driven device, the quiescent current is very low and independent of output loading (maximum of 230A over the full range of output current). This LDO family also features a sleep mode; applying a high signal to EN
