AP2303MPTR-G1 Description

Short technical summary and product information.

The AP2303MPTR-G1 from Diodes Incorporated is a low dropout linear regulator specifically designed for DDR-SDRAM systems. It efficiently generates the required termination voltage, capable of sourcing or sinking up to 1.75A of current continuously.

 

This regulator offers precise output voltage regulation, tracking the reference voltage (1/2VDDQ) within ±10mV. It supports DDR-II, DDR-III, DDR-IIIL, and DDR-IV standards with corresponding termination voltages. Key features include soft start-up, shutdown circuitry triggered by input voltage levels, over-temperature protection, and current limit protection for both source and sink operations.

 

The AP2303MPTR-G1 is available in an 8-SOIC package with an exposed pad, suitable for surface mounting. It operates within a temperature range of -40°C to 85°C and requires a minimum 10µF output ceramic capacitor for optimal performance. The device is RoHS3 compliant and halogen-free.

 

Applications for this regulator include DDR memory systems in desktop PCs, notebook motherboards, graphic cards, STBs, LCD-TVs, and Web-TVs.
