The TPS701xx family of voltage regulators offers very low dropout voltage and dual outputs with power up equence control, which is designed primarily for DSP applications. These devices have extremely low noise utput performance without using any added filter bypass capacitors and are designed to have a fast transient esponse and be stable with 10 uF low ESR capacitors.
These devices have fixed 3.3-V/2.5-V, 3.3-V/1.8-V, 3.3-V/1.5-V, 3.3-V/1.2-V, and adjustable/adjustable voltage ptions. The 3.3-V output regulator (regulator 1) can support up to 500 mA, and the other regulator (regulator ) can support up to 250 A. Separate voltage inputs allow the designer to configure the source power.
ecause the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 170 mV n regulator 1) and is directly proportional to the output current. Additionally, since the PMOS pass element is voltage-driven device, the quiescent current is very low and independent of output loading (maximum of 225 A over the full range of output current). This LDO family also features a sleep mode; applying a high signal to EN (enable) shuts down both regulators, reducing the input current to 1 A at TJ = 25°C.
