AP2302L Datasheet, PDF (1/12 Pages) BCD Semiconductor Manufacturing Limited – 2A DDR TERMINATION REGULATOR

Preliminary Datasheet
2A DDR TERMINATION REGULATOR
General Description
Features
AP2302L
The AP2302L linear regulator is designed to meet the
JEDEC specification SSTL-2 and SSTL-18 for termi-
nation of DDR-SDRAM. The regulator can sink or
source up to 2A current continuously, providing
enough current for most DDR applications. V_OUT is
designed to track the V_REF voltage within a ± 20mV
tolerance over the entire current range while prevent-
ing shooting through on the output stage. On-chip ther-
mal limiting provides protection against a combination
of high current and ambient temperature which would
create an excessive junction temperature.
· Support Both DDR I (1.25V_TT) and DDR II
(0.9V_TT) Requirements
· Source and Sink Current up to 2A
· High Accuracy Output Voltage at Full-load
· Adjustable V_OUT by External Resistors
· Shutdown for Standby or Suspend Mode
Operation with High-impedance Output
Applications
The AP2302L, used in conjunction with series termi- _{· DDR-SDRAM Termination}
nation resistors, provides an excellent voltage source
for active termination schemes of high speed transmis-
sion lines as those seen in high speed memory buses
