BD3539FVM - Termination Regulator

General Description

BD3539 is a termination regulator that complies with JEDEC requirements for DDR1-SDRAM, DDR2-SDRAM, and DDR3-SDRAM.

This linear power supply uses a built-in N-channel MOSFET and high-speed OP-AMPS specially designed to provide excellent transient response.

Key Features

  • Incorporates a Push-Pull Power Supply for Termination (VTT).
  • Incorporates a Reference Voltage Circuit (VREF).
  • Incorporates an Enabler.
  • Incorporates an Under Voltage Lockout (UVLO).
  • Incorporates a Thermal Shutdown Protector (TSD).
  • Compatible with Dual Channel (DDR1, DDR2, DDR3).
  • Usable Ceramic Capacitor at Output.

cription BD3539 is a termination regulator that complies with JEDEC requirements for DDR1-SDRAM, DDR2-SDRAM, and DDR3-SDRAM. This linear power supply uses a built-in N-channel MOSFET and high-speed OP-AMPS specially designed to provide excellent transient response. It has a sink/source current capability of up to 1A and has a power supply bias requirement of 3.3 V (for DDR2 and DDR3) and 5.0 V (for DDR1, DDR2, and DDR3) for driving the N-channel MOSFET. By employing an independent reference voltage input (VDDQ) and a feedback pin (VTTS), this termination regulator provides excellent output voltage accuracy and load regulat
