The Texas Instruments TPS78633KTTR is a high-performance, low-dropout (LDO) linear voltage regulator designed for demanding applications. It provides a stable 3.3V fixed output voltage with a maximum output current of 1.5A. This device is built on an advanced BiCMOS fabrication process, enabling very low dropout voltages and excellent transient response.
Key electrical characteristics include a wide input voltage range (2.7V to 5.5V), low quiescent current of 265µA typical, and ultralow noise performance of 48µVRMS. The regulator also boasts high Power Supply Rejection Ratio (PSRR) of up to 59dB at 100Hz, making it suitable for noise-sensitive applications like RF circuits and audio systems.
Designed for ease of use, the TPS78633KTTR features an Enable control pin for power sequencing and soft-start functionality. It offers robust protection features including over-current, over-temperature, reverse polarity, and under-voltage lockout (UVLO).
The TPS78633KTTR is supplied in a surface-mount DDPAK/TO-263-5 package, suitable for various electronic designs. Its operating temperature range is -40°C to 125°C, ensuring reliable performance in harsh environments.
