TPS78618DCQ Description

Short technical summary and product information.

The Texas Instruments TPS78618DCQ is a 1.5A low-dropout linear voltage regulator designed for applications requiring high power supply rejection ratio (PSRR) and ultralow noise. It provides a stable 1.8V fixed output voltage and is capable of delivering up to 1.5A of current.

 

Key features include a very low dropout voltage of 390mV at full load, fast start-up time of 50µs, and excellent load and line transient responses. The device also offers protection features such as over current, over temperature, reverse polarity, and under voltage lockout (UVLO). Its ultralow noise performance, with an output noise of 48µVRMS, makes it suitable for noise-sensitive analog circuits.

 

The TPS78618DCQ is housed in a SOT-223-6 package, suitable for surface mount applications. It operates within a temperature range of -40°C to 125°C. The regulator family is stable with a small 1µF ceramic capacitor on the output, simplifying circuit design.

 

This LDO is ideal for RF applications like VCOs and receivers, as well as audio circuits and wireless communication devices such as Bluetooth and cellular phones.
