TPS79618DCQ Description

Short technical summary and product information.

The Texas Instruments TPS79618DCQ is a 1A low-dropout (LDO) linear voltage regulator designed for applications requiring low noise and high power-supply rejection ratio (PSRR). This specific device provides a fixed output voltage of 1.8V and is stable with a 1µF ceramic capacitor.

 

Key electrical characteristics include a maximum output current of 1A, a typical dropout voltage of 220mV at full load, and a typical quiescent current of 0.26mA. It features excellent load and line transient responses and a fast start-up time of approximately 50µs. Protection features include over current, over temperature, reverse polarity, and under voltage lockout.

 

The TPS79618DCQ is housed in a SOT-223-6 surface-mount package. Its high PSRR and ultralow noise performance make it ideal for sensitive analog circuits, RF applications, and portable electronics where power efficiency and signal integrity are critical.

 

This regulator operates within a temperature range of -40°C to 125°C. The device includes an enable pin for power control. Its stability with a small output capacitor simplifies board design.
