TPS79633QDCQRG4 - Texas Instruments

The TPS79633QDCQRG4 is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments, designed to offer a stable and reliable power supply for a wide range of applications. This regulator is notable for its low noise output, which makes it an ideal choice for sensitive RF or analog circuitry that requires a clean power source to operate effectively.

Key Features:

• Output Voltage: The device provides a fixed output voltage of 3.3V, which is common for many digital and analog circuits.
• High Output Current: It can deliver up to 1A of continuous output current, catering to the needs of power-hungry components.
• Low Dropout: The low dropout voltage allows the regulator to continue delivering a regulated output even when the supply voltage is very close to the output voltage, enhancing efficiency and battery life in portable applications.
• Low Noise: This LDO features an exceptionally low output noise level of 33μVRMS, making it suitable for precision applications such as medical equipment and high-fidelity audio.
• Stable with Low ESR Capacitors: The TPS79633QDCQRG4 is stable with ceramic capacitors, which have lower equivalent series resistance (ESR) than other types, reducing the overall noise and improving reliability.
• Thermal Shutdown and Overcurrent Protection: Built-in safety features protect the device and the application from damage due to excessive heat or current.
• Adjustable Output: While the device typically provides a 3.3V output, it also offers the flexibility to adjust the voltage with external resistors.
