TPS78401QDBVRQ1 Description

Short technical summary and product information.

The TPS78401QDBVRQ1 from Texas Instruments is a single-output, positive linear voltage regulator. It is designed for applications requiring stable power delivery with a maximum output voltage of 5.5V. This device features a low quiescent current of 40 µA, making it suitable for power-sensitive designs.

 

Key electrical characteristics include a voltage dropout of 0.9V at 300mA and a Power Supply Rejection Ratio (PSRR) ranging from 60dB to 30dB across a frequency range of 1kHz to 1MHz. Protection features such as over current, over temperature, and under voltage lockout (UVLO) are integrated for enhanced reliability. Control features include current limit, enable, and soft start.

 

The TPS78401QDBVRQ1 operates within a wide temperature range of -40°C to 150°C (TJ). It is available in a SOT-23-5 package and utilizes surface mount technology for integration into compact electronic circuits. The package is also referred to as SC-74A or SOT-753.
