The Texas Instruments TPS79418DCQ is a 250mA, low-dropout linear voltage regulator featuring ultralow noise and high power-supply rejection ratio (PSRR). It provides a fixed 1.8V output and is designed for applications requiring stable power.
Key electrical characteristics include a very low dropout voltage of 155mV at full load, enabling operation with lower input voltages. The device offers high PSRR, with values up to 65dB at 100Hz, making it suitable for noise-sensitive applications. It also features fast start-up times of approximately 50µs.
The TPS79418DCQ is available in a SOT-223-6 surface-mount package. Its operating temperature range is -40°C to 125°C. The regulator includes enable control and protection features such as over current, over temperature, reverse polarity, and under voltage lockout (UVLO).
This regulator is ideal for RF applications, portable electronics, and other systems where low noise and high power supply rejection are critical. Its stable operation with a small 2.2µF ceramic capacitor on the output simplifies design.
