Key Features
- High output current up to 3A with low dropout voltage, ideal for high-current DDR termination and point-of-load regulation
- Wide adjustable output voltage range from 0.6V to 3.6V covering DDR, DDR2, and DDR3 memory supply requirements
- Input voltage range of 1.2V to 3.6V enables direct powering from low-voltage system rails without pre-regulation
- Compact 10-pin HTSSOP with exposed pad (MSOP PowerPAD) package minimizes PCB footprint and improves thermal dissipation
- Single-function design with one output simplifies BOM and reduces external component count for power-sensitive designs
Applications
The TPS51100DGQ is widely used in DDR, DDR2, and DDR3 memory bus termination circuits in laptops, desktops, and embedded computing platforms where stable, high-current low-voltage rails are critical. It also serves as a point-of-load regulator in telecom equipment, industrial controllers, and network switches requiring tight voltage accuracy from low-rail supplies. Its compact HTSSOP package and broad input range make it suitable for space-constrained mobile and portable device power management designs.
