TPS7A4518DCQR Description

Short technical summary and product information.

The Texas Instruments TPS7A4518DCQR is a low-dropout (LDO) linear voltage regulator optimized for fast transient response. It provides a stable 1.8V fixed output voltage and can deliver up to 1.5A of current. The device operates with an input voltage up to 20V and features a low dropout voltage of 0.45V at 1.5A.

 

Key electrical characteristics include a low quiescent current of 1mA and high ripple rejection of 68dB at 1kHz. Protection features include over current, over temperature, and reverse polarity protection. The regulator is enabled via a control pin.

 

This component is supplied in a SOT-223-6 surface-mount package. Its operating temperature range is -40°C to 125°C, making it suitable for various industrial applications. The design prioritizes fast transient response and stability with a 10µF ceramic output capacitor.
