TPS79618DCQR Description

Short technical summary and product information.

The Texas Instruments TPS79618DCQR is a high-performance, low-power linear voltage regulator designed for noise-sensitive applications. It provides a stable 1.8V output with a maximum current of 1A. Key features include ultralow noise operation, with output noise typically measuring 40 µVRMS (TPS79630), and excellent power-supply rejection ratio (PSRR) ranging from 59dB to 42dB across a frequency range of 100Hz to 100kHz.

 

This regulator is designed for stability with a small 1µF ceramic capacitor on the output. It boasts a fast start-up time of approximately 50µs, making it suitable for applications requiring quick power-up sequences. The device operates over a temperature range of -40°C to 125°C and includes protection features such as over current, over temperature, reverse polarity, and under voltage lockout (UVLO).

 

The TPS79618DCQR is supplied in a compact SOT-223-6 surface-mount package, facilitating integration into space-constrained designs. Its combination of low noise, high PSRR, and fast transient response makes it ideal for RF applications, audio circuits, and portable electronics.
