HELIOS - LDNS
1A NEGATIVE VOLTAGE REGULATOR
The CHT-LDNS is a high-temperature 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.
Key features
- Temperature range: -55°C to 225°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, TO-3 and bare die
Applications
Power supplies for high-temperature electronic systems used in Well logging, Automotive, Aeronautics or Aerospace applications
