2V, and Dual Adjustable Outputs • Open Drain Power-On Reset with 120ms Delay • Open Drain Power Good for Regulator 1 and Regulator 2 • Ultralow 190μA (typ) Quiescent Current • 1μA Input Current During Standby • Low Noise: 65μVRMS Without Bypass Capacitor • Quick Output Capacitor Discharge Feature • One Manual Reset Input • 2% Accuracy Over Load and Temperature • Undervoltage Lockout (UVLO) Feature • 20-Pin PowerPAD™ TSSOP Package • Thermal Shutdown Protection 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 500mA and 250mA by regulator 1 and regulator 2 respectively.
Quiescent current is typically 190μA 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.
