DUAL-OUTPUT, LOW DROPOUT VOLTAGE REGULATORS

WITH INTEGRATED SVS FOR SPLIT VOLTAGE SYSTEMS

23

• Dual Output Voltages for Split-Supply

The TPS708xx is a low dropout voltage regulator with

Applications

integrated SVS (RESET, POR, or power on reset)

and power good (PG) functions. These devices are

• Independent Enable Functions (See Part

capable of supplying 250 mA and 125 mA by

Number TPS707xx for Sequenced Outputs)

regulator 1 and regulator 2 respectively. Quiescent

• Output Current Range of 250 mA on Regulator

current is typically 190

µA at full load. Differentiated

1 and 125 mA on Regulator 2

features, such as accuracy, fast transient response,

• Voltage Options: 3.3-V/2.5-V, 3.3-V/1.8-V,

SVS supervisory circuit (power on reset), manual

reset input, and independent enable functions provide

3.3-V/1.5-V, 3.3-V/1.2-V, and Dual Adjustable

a complete system solution.
