Linear & Switching Voltage Regulators

TPS73HD325PWPR Description

The TPS73HD325PWPR from Texas Instruments is a high-performance, dual-output linear voltage regulator designed for precision power management in demanding applications. This fixed-output regulator delivers 2.5V and 3.3V simultaneously, with a maximum input voltage of 10V and an output current capability of 750mA per channel. Packaged in a 28-pin HTSSOP and available in Tape & Reel (TR), it is optimized for surface-mount designs. The device features low quiescent current (415 µA) and low supply current (550 µA max), making it ideal for power-sensitive systems. With 51dB to 49dB PSRR (120Hz), it ensures stable output under noisy conditions.

TPS73HD325PWPR Features

• Dual Fixed Outputs: Provides 2.5V and 3.3V simultaneously, eliminating the need for multiple regulators.
• High Efficiency: Low dropout and 415 µA quiescent current enhance power efficiency.
• Robust Protection: Includes over-current, over-temperature, and reverse-polarity protection for reliability.
• Control & Monitoring: Features enable and reset functions for flexible power sequencing.
• Excellent Noise Immunity: High PSRR (51dB @ 120Hz) ensures clean output in noisy environments.
• Compact & Reliable: 28-pin HTSSOP package with MSL 2 (1 Year) moisture sensitivity, suitable for industrial applications.
