HELIOS - LDOP

Fixed positive voltage regulator

The CHT-LDOP is a positive low-dropout linear voltage regulator. The output voltage can be chosen from a long list of available values (see table below). CHT-LDOP is adapted to system with only positive power supply.

Typical performances

  • Temperature range: -55°C to 225°C (operational up to 300°C)
  • Input Voltage: Vout + 2V to 25V (30V for High Voltage input)
  • Maximum Output current: 1A
  • Total precision (absolute+drift): 2%
  • Short-Circuit protection: Foldback
  • Tuning by bonding
  • 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.

 

 

Application notes

  • Voltage regulator short-circuit protection and associated potential startup issue: AN-06002
  • Selecting correct CISSOID's regulator depending on application: AN-06016
  • Power Dissipation Considerations During Short Circuit Conditions:  AN-090477
