Voltage Regulator

Wide selection is available like as output current range of 100mA to 1.2A, fixed or variable output voltage, CMOS type or Bipolar type. Fixed voltage option is selectable from 0.8V to 15V by a 0.1V step.(Only ELM98 and LM99 can reach 15V.)
431 type shunt regulator is also available from a ELM regulator lineup.
