The Texas Instruments TPS70445PWPR is a dual-channel ultra-low-dropout (LDO) linear voltage regulator designed for split-supply applications. This device provides two independent output voltages, with options including 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. Regulator 1 can supply up to 1A, while Regulator 2 can supply up to 2A.
Key features include independent enable functions, open-drain power-on reset with a 120-ms delay, and open-drain power good signals for both regulators. It boasts ultralow quiescent current of 185µA typical and 2µA input current during standby. The regulator offers fast transient response, low noise (78µV RMS without bypass capacitor), and a quick output capacitor discharge feature.
Protection features include over current, over temperature, reverse polarity, and undervoltage lockout (UVLO). The TPS70445PWPR operates over a temperature range of -40°C to 125°C and is available in a 24-pin HTSSOP package, suitable for surface mounting.
This part is noted as 'NOT RECOMMENDED FOR NEW DESIGNS' by the manufacturer, suggesting alternative parts should be considered for new projects.
