description

The TPS702xx is a low dropout voltage regulator

with integrated SVS (RESET, POR, or power on

reset) and power good (PG) functions. These

devices are capable of supplying 500 mA and

250 mA by regulator 1 and regulator 2 respective-

ly. Quiescent current is typically 190

µA at full

load. Differentiated features, such as accuracy,

fast transient response, SVS supervisory circuit

(power on reset), manual reset input, and

independent enable functions provide a complete

system solution.
