BD35395FJ-ME2 ROHM

Datasheet Regulator IC Series for Automotive Termination Regulator for DDR-SDRAMs BD35395FJ-M General Description Key Specifications BD35395FJ-M is a termination regulator compatible with Input Voltage Range: 2.7V to 5.5V JEDEC DDR1/2/3/3L-SDRAM, which functions as a linear Termination Input Voltage: 1.0V to 5.5V power supply incorporating an N-channel MOSFET and VDDQ Reference Voltage: 1.0V to 2.75V provides a sink/source current capability up to 1A Output Current: -1.01.0A(Max) respectively. A built-in high-speed OP-AMP specially Upper Side ON Resistance: 0.35(Typ) designed offers an excellent transient response. Lower Side ON Resistance: 0.35(Typ) Requires 3.3 volts or 5.0 volts as a bias power supply to Standby Current: 0.5mA (Typ) drive the N-channel MOSFET. Has an independent Operating Temperature Range: -40C to +105C reference voltage input pin (VDDQ) and an independent feedback pin (VTTS) to maintain the accuracy in voltage Package(s) W(Typ) x D(Typ) x H(Max) required by JEDEC, and offers an excellent output voltage SOP-J8 4.90mm x 6.00mm x 1.65mm accuracy and load regulation. Features Incorporates a push-pull power supply for termination (VTT). Incorporates an enabler. Incorporates an under voltage lockout (UVLO). Employs SOP-J8 package : 4.9 6.01.65(mm). Incorporates a thermal shutdown protector (TSD). Operates with input voltage from 2.7 to 5.5 volts. Compatible with Dual Channel (DDR1,DDR2,DDR3/DDR3L) Incorporates PGOOD function.
