TPS79918DDCT Description

Short technical summary and product information.

The Texas Instruments TPS79918DDCT is a linear voltage regulator with a fixed output voltage of 1.8V and a maximum output current of 200mA. It operates from an input voltage range of 2.7V to 6.5V.

 

This LDO regulator features low quiescent current (40µA typical) and high Power Supply Rejection Ratio (PSRR) of 38dB at 100kHz, making it suitable for noise-sensitive applications. It offers a low dropout voltage of 100mV at 200mA and 2% overall accuracy across load, line, and temperature variations. Protection features include over current, over temperature, reverse polarity, and under voltage lockout.

 

The TPS79918DDCT is available in a SOT-23-5 Thin package, designed for surface mounting. Its operating temperature range is -40°C to 125°C. The device includes an enable control feature for power management.
