Product Summary
The TPS70458PWP is a dual-output low-dropout voltage regulator with integrated SVS (RESET, POR, or power on reset)and power good (PG) functions. The TPS70458PWP is capable of supplying 1 A and 2 A by regulator 1 and regulator 2 respectively. Quiescent current is typically 185μA at full load. Differentiated features, such as accuracy,fast transient response, SVS supervisory circuit (power onreset), manual reset input, and independent enable functions provide a complete systemsolution.
Parametrics
TPS70458PWP absolute maximum ratings: (1)Input voltage, VI: 2.7 to 6V; (2)Output current, IO (regulator 1): 0 to 500mA; (3)Output current, IO (regulator 2): 0 to 250mA; (4)Output voltage range (for adjustable option): 1.2 to 25.5V; (5)Operating virtual junction temperature, TJ: -40 to 125℃.
Features
TPS70458PWP features: (1)Dual Output Voltages for Split-Supply Applications; (2)Selectable Power Up Sequencing for DSP Applications; (3)Output Current Range of 500 mA on Regulator 1 and 2A on Regulator 2; (4)Fast Transient Response; (5)Voltage Options are 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 Dual Adjustable Outputs; (6)Open Drain Power-On Reset With 120-ms Delay; (7)Open Drain Power Good for Regulator 1; (8)Ultra Low 185μA (typ) Quiescent Current; (9)2 μA Input Current During Standby; (10)Low Noise: 78 μVRMS Without Bypass Capacitor; (11)Quick Output Capacitor Discharge Feature; (12)Two Manual Reset Inputs; (13)2% Accuracy Over Load and Temperature; (14)Undervoltage Lockout (UVLO) Feature; (15)24-Pin PowerPAD TSSOP Package; (16)Thermal Shutdown Protection.
