LM431A/C

SKU: LM431A/C

  • HTC KOREA

Programmable precision shunt regulator (2.500V)

HTC Korea LM431A/C is a three-terminal adjustable shunt regulator with specified thermal stability over applicable temperature VREF (Approx. 2.5V) and 40V with two external resistors. This device has a typical dynamic output impedance of 0.2 Ω. Active output circuitry provides a very sharp turn-on characteristic, making this device excellent replacement for zener diodes in many applications. The LM431 is characterized for operation from -40°C to +125°C.

 

 

LM431A/C features

  • Programmable Output Voltage to 40V
  • Guaranteed 0.5% Reference Voltage Tolerance
  • Low (0.2 ohm Typ.) Dynamic Output Impedance
  • Cathode Current Range(Continuous) - 100 ~ 150 mA
  • Equivalent Full Range Temperature Coefficient of 50ppm/°C
  • Temperature Compensated For Operation Over Full Rate Operating Temperature Range
  • Low Output Noise Voltage
  • Fast Turn-on Response
  • SOT-23 3L Package
