TPS75833KTTT

TPS75833KTTT Description

The TPS75833KTTT is a high-performance, fixed-output linear voltage regulator from Texas Instruments, designed to deliver a stable 3.3V output at up to 3A of continuous current. With a wide input voltage range of up to 5.5V, this regulator is optimized for applications requiring efficient power management with minimal dropout voltage (0.3V @ 3A). The device is housed in a DDPAK/TO-263-5 package, making it suitable for surface-mount designs. Although marked as obsolete, it remains a reliable choice for legacy systems due to its robust protection features and low quiescent current (200 µA).

TPS75833KTTT Features

• High Current Output: Supports 3A load current, ideal for power-hungry applications.
• Low Dropout Voltage: 0.3V @ 3A ensures efficient operation even with tight input-output differentials.
• Advanced Protection: Includes over-current, over-temperature, reverse polarity, and under-voltage lockout (UVLO) for enhanced system reliability.
• Low Quiescent Current: 200 µA minimizes power loss in standby modes.
• Excellent PSRR: 62dB @ 100Hz reduces noise for sensitive analog/digital circuits.
• Enable Control: Allows for power sequencing and energy-saving modes.
• RoHS3 Compliant & REACH Unaffected: Meets environmental and regulatory standards.

TPS75833KTTT Applications

The TPS75833KTTT excels in systems requiring stable, high-current power delivery, such as:

• Industrial Automation: Powering sensors, PLCs, and motor controllers.
• Telecommunications: Base stations and networking equipment.
• Embedded Systems: Single-board computers and FPGA power rails.
• Automotive Electronics: Infotainment and ADAS modules (non-safety-critical).
• Legacy Designs: Suitable for maintaining or upgrading older systems where component availability is limited.

Conclusion of TPS75833KTTT

The TPS75833KTTT is a robust, high-current linear regulator with exceptional efficiency and protection features. While obsolete, its 3.3V fixed output, low dropout, and high PSRR make it a strong candidate for demanding applications requiring reliable power management. Engineers working on legacy or high-current designs will find its performance and protection mechanisms highly advantageous.
