DDR-SDRAM Termination Regulator
BD3530F
Description
BD3530F is a regulator developed as termination
power supply of standard DDR-SDRAM that is
used for PC.
Industry's highest speed of transient response
characteristic is realized. The built-in FET can sink
and source load current of 3A(max.)
Waveform quality when data is transferred at high
speed can't be deteriorated.
BD3530F meets the bus line standards SSTL-2 of
DDR-SDRAM.
High-reliability can be realized for any applications
using DDR-SDRAM.
Features
1) Built-in push-pull regulator for termination(VTT)
2) Built-in reference voltage circuit(VREF)
3) Built-in enable function
4) Built-in under voltage lock out circuit
5) Package SOP8
6) Built-in thermal shut down circuit
