Linear & Switching Voltage Regulators

TPS73HD325PWP Description

The TPS73HD325PWP from Texas Instruments is a dual-output, low-dropout (LDO) linear voltage regulator designed for precision power management in demanding applications. This 28-pin HTSSOP packaged IC delivers fixed outputs of 2.5V and 3.3V with a maximum input voltage of 10V, supporting up to 750mA per channel. It features ultra-low quiescent current (415 µA) and excellent power supply ripple rejection (51dB ~ 49dB at 120Hz), making it ideal for noise-sensitive systems. With over-current, over-temperature, and reverse-polarity protection, it ensures robust operation in harsh environments.

TPS73HD325PWP Features

• Dual Outputs: Independent 2.5V and 3.3V rails for multi-voltage systems.
• High Efficiency: Low dropout and 550 µA max supply current enhance power efficiency.
• Advanced Protection: Integrated safeguards against over-current, thermal overload, and reverse polarity.
• Control Features: Enable and reset functions for flexible power sequencing.
• Low Noise: High PSRR (51dB) minimizes output ripple, critical for analog/RF circuits.
• Compact & Reliable: 28-pin HTSSOP package with MSL 2 (1 Year) moisture sensitivity.

TPS73HD325PWP Applications

• Portable Electronics: Battery-powered devices requiring stable dual voltages.
• Industrial Systems: PLCs, sensors, and control modules benefiting from robust protection.
• Medical Equipment: Low-noise power for precision analog circuits.
• Automotive Electronics: Reliable voltage regulation in infotainment and ADAS.
• Embedded Systems: Microcontroller and FPGA power supplies with sequencing control.

Conclusion of TPS73HD325PWP

The TPS73HD325PWP stands out for its dual-output precision, low quiescent current, and robust protection features, making it a superior choice for applications demanding reliability and efficiency. Its high PSRR and compact form factor cater to space-constrained, noise-sensitive designs, while TI's quality assurance (ROHS3, REACH Unaffected) ensures compliance with global standards. Ideal for industrial, medical, and automotive systems, this LDO regulator combines performance with durability.
