TPS79601KTTT

TPS79601KTTT Description

The TPS79601KTTT is a high-performance, adjustable linear voltage regulator from Texas Instruments, designed to deliver a stable 1A output current with an input voltage range up to 5.5V. This positive-output regulator features an adjustable output voltage from 1.2V to 5.5V, making it versatile for a wide range of low-voltage applications. Although marked as obsolete, it remains a reliable choice for legacy designs due to its robust protection features, including over-current, over-temperature, reverse polarity, and under-voltage lockout (UVLO). Packaged in a surface-mount DDPAK (TO-263) and supplied in Tape & Reel (TR), it is suitable for automated assembly processes.

TPS79601KTTT Features

• High PSRR (59dB @ 100Hz, 42dB @ 100kHz): Ensures excellent noise rejection for sensitive analog/digital circuits.
• Low Quiescent Current (385µA): Enhances efficiency in battery-powered applications.
• Enable Control: Allows for power sequencing and energy-saving modes.
• Robust Protection: Includes over-current, thermal shutdown, reverse polarity, and UVLO for system reliability.
• RoHS3 Compliant & REACH Unaffected: Meets environmental and regulatory standards.
• Wide Adjustable Output (1.2V–5.5V): Supports flexible voltage requirements.

TPS79601KTTT Applications

• Portable Electronics: Ideal for battery-operated devices requiring stable voltage rails.
• Industrial Control Systems: Suitable for sensors, PLCs, and low-noise analog circuits.
• Embedded Systems: Powers microcontrollers, FPGAs, and peripherals with precise voltage regulation.
• Automotive Subsystems: Used in infotainment, telematics, and ADAS (where legacy designs persist).
• Medical Devices: Benefits from low-noise performance in diagnostic equipment.

Conclusion of TPS79601KTTT

The TPS79601KTTT excels in applications demanding high PSRR, low quiescent current, and robust protection. While obsolete, its adjustable output, enable control, and thermal resilience make it a preferred choice for legacy or long-lifecycle designs. Engineers should evaluate alternative TI regulators for new projects but can rely on this model for proven performance in noise-sensitive, power-constrained systems.
