LM2940H

SKU: LM2940H

  • HTC KOREA

1.0A high-voltage VLDO voltage regulator

HTC Korea  LM2940H fixed positive voltage regulator features the ability to source 1.0A of output current with a dropout voltage of typically 0.4V and a maximum of 0.7V over the entire temperature range. Designed also for vehicular applications, the LM2940H and all regulated circuitry are protected from reverse battery installations or 2-battery jumps. During line transients, such as load dump when the input voltage can momentarily exceed the specified maximum operating voltage, the regulator will automatically shut down to protect both the internal circuits and load. Short circuit and thermal overload protection are also provided.

 

LM2940H features :

  • Operational VIN up to +26V
  • +60V/−20V voltage transients
  • Output current in excess 1.0A
  • Dropout voltage typically 0.4V @ IOUT = 1.0A
  • Reverse battery protection
  • Internal short circuit current limit
  • Available with 3.3V and 5.0V output voltage

 

LM2940H applications :

  • Automotive and Industrial applications
