The Texas Instruments TPS78633DCQR is a high-performance linear voltage regulator designed for applications requiring low noise and high power supply rejection ratio (PSRR). It provides a stable 3.3V fixed output voltage with a maximum output current of 1.5A.
Key electrical characteristics include a typical dropout voltage of 390mV at full load and a quiescent current of 265µA, which drops to less than 1µA in standby mode. The regulator boasts ultralow noise performance (48µVrms) and a fast start-up time of 50µs, making it ideal for noise-sensitive circuits.
With features like overcurrent, overtemperature, and reverse polarity protection, the TPS78633DCQR ensures reliable operation. It is designed to be stable with a 1µF ceramic capacitor on the output, offering excellent load and line transient response.
The device is supplied in a SOT-223-6 surface-mount package, suitable for compact designs. Its operating temperature range is -40°C to 125°C, accommodating demanding environments. Applications include RF circuits like VCOs and receivers, as well as audio systems and wireless communication devices.
