TPS76633D Description

TPS76633D Description

The TPS76633D from Texas Instruments is a fixed-output, low-dropout (LDO) linear voltage regulator designed to deliver a stable 3.3V output with a maximum current of 250mA. It operates with an input voltage range up to 10V, making it suitable for a variety of power management applications. With a low dropout voltage of 0.4V at 250mA, it ensures efficient performance even when the input voltage is close to the output level. The device features ultra-low quiescent current (50 µA), enhancing power efficiency in battery-operated systems. Packaged in an 8-pin SOIC tube, it is optimized for surface-mount applications and complies with RoHS3 and REACH environmental standards.

TPS76633D Features

  • High PSRR (63dB at 1kHz): Ensures clean output voltage by rejecting input noise, ideal for sensitive analog/digital circuits.
  • Advanced Protection: Includes over-current, over-temperature, and reverse-polarity protection for robust operation.
  • Control & Monitoring: Features enable pin and power-good signal for system-level power sequencing and fault detection.
  • Low Quiescent Current (50 µA): Extends battery life in portable devices.
  • Wide Input Range (Up to 10V): Supports diverse power sources, including unregulated adapters or batteries.
  • Last Time Buy Status: Engineers should consider alternatives for new designs but can still procure for legacy systems.

TPS76633D Applications

  • Portable Electronics: Ideal for handheld devices, IoT sensors, and wearables due to low Iq and small footprint.
  • Industrial Systems: Suitable for PLC modules, instrumentation, and control systems requiring stable 3.3V rails.
  • Automotive Electronics: Used in infotainment and telematics where reverse-polarity protection is critical.
  • Embedded Systems: Powers microcontrollers, FPGAs, and memory in space-constrained designs.

Conclusion of TPS76633D

The TPS76633D stands out for its low dropout, high PSRR, and integrated protections, making it a reliable choice for noise-sensitive and power-efficient applications. While it is in Last Time Buy status, its performance benefits—such as enable control and power-good monitoring—make it a strong candidate for legacy or low-power designs. Engineers should evaluate its successor models for new projects but can leverage this regulator for existing systems requiring a compact, high-performance LDO solution.
