TPS7A4518KTTR Description

Short technical summary and product information.

The Texas Instruments TPS7A4518KTTR is a low-dropout (LDO) linear voltage regulator designed for applications requiring fast transient response. It provides a stable 1.8V output voltage with a maximum output current of 1.5A. The device features a low dropout voltage of 300mV at 1.5A and a high ripple rejection ratio of 68dB at 120Hz.

 

This regulator is suitable for sensitive RF supply applications due to its low output noise. It includes protection features such as over current, over temperature, and reverse polarity protection. The TPS7A4518KTTR is available in a surface-mount TO-263-5 package, also known as DDPAK/TO-263-5, and operates within a temperature range of -40°C to 125°C.

 

Key electrical characteristics include a 20V maximum input voltage and a quiescent current of 1mA. The fixed output configuration simplifies design, and the enable control feature allows for power management.
