LD49300PT12R Description

Short technical summary and product information.

The LD49300PT12R from STMicroelectronics is a high-bandwidth, low-dropout, 3.0 A voltage regulator designed for powering core voltages of low-power microprocessors. It operates with an input voltage range of 1.4 V to 5.5 V and a bias supply range of 3 V to 6 V.

 

This regulator offers a fixed output voltage of 1.2 V and can deliver up to 3 A of current. Key features include a maximum dropout voltage of 400 mV at 3 A, ±1.5% initial tolerance, and excellent line and load regulation. It is stable with ceramic capacitors and provides very fast transient response up to 10 MHz bandwidth.

 

The LD49300PT12R is housed in a PPAK package suitable for surface mounting. It includes logic-controlled shutdown, thermal shutdown, and current limit protection, making it suitable for applications such as graphics processors, PC add-in cards, and microprocessor core voltage supplies.
