HELIOS - LDNS

1A Negative voltage regulator

The CHT-LDNS is a Negative low-dropout linear voltage regulator. The output voltage can be chosen from a list of available values (see table below). CHT-LDNS is adapted to system with single or symmetrical power supply.

Typical performances

  • Temperature range: -55°C to 225°C (operational up to 300°C)
  • Input Voltage: Vout -2V to -30V
  • Maximum Output current: 1A
  • Total precision (absolute+drift): 2%
  • Short-Circuit protection: Foldback
  • Quiescent current: 3mA
  • Available packaging: TO-254

 

Application

Power supplies for high-temperature electronic systems used in Well logging, Automotive, Aeronautics or Aerospace applications

If you need support for your high temperature power supply design, just contact Cissoid.
