TPS79418DCQR Description

Short technical summary and product information.

The Texas Instruments TPS79418DCQR is a 250mA low-dropout (LDO) linear voltage regulator with a fixed 1.8V output. It is designed for applications requiring high power-supply rejection ratio (PSRR), ultralow noise, and fast start-up times.

 

Key electrical characteristics include a maximum input voltage of 5.5V and a typical dropout voltage of 155mV at 250mA. The device also features a typical quiescent current of 170µA and includes enable control functionality. Protection features include over current, over temperature, reverse polarity, and under voltage lockout.

 

This regulator is stable with a small 2.2µF ceramic capacitor on the output. It is supplied in a SOT-223-6 surface-mount package, making it suitable for space-constrained designs. The operating temperature range is -40°C to 125°C.

 

Applications benefiting from its low noise and high PSRR include portable RF electronics, wireless LAN, and audio components.
