General Description
AP1250GM / AP1250GH
1.5A / 3A Bus Termination Regulator
Pb Free Plating Product
AP1250GM/H is a linear regulator designed as a cost-effective solution for active
termination of DDR SDRAM. The converting voltage range is from 1.6V to 6V into a
desired output voltage, which is adjusted by two external resistors. The current
sourcing and sinking capability of the regulator is up to 1.5A/3A while the output
voltage within 2%/3%.
This device provides on-chip thermal shutdown and current limit functions for circuit
tolerance of the output fault conditions. SO-8 and TO-252-5L packages are available
for all commercial and industrial surface mount applications.
Features
▼ Ideal for DDR-I and DDR-II applications
▼ Capable of sourcing and sinking current 1.5A/3A
▼ Current limiting protection
▼ Thermal protection
▼ Current-shoot-through protection
▼ High accuracy output voltage at full load
▼ Minimum external components
▼ Adjustable VOUT by external resistors
▼ Shutdown for standby or suspend mode operation with high-impedance output
