HELIOS - LDOS
1A POSITIVE VOLTAGE REGULATOR
The CHT-LDOS is a high-temperature positive low-dropout linear voltage regulator. The output voltage can be chosen from a list of available values (see table below). CHT-LDOS is adapted to system using a symmetrical power supply.
Key features
- Temperature range: -55°C to 225°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
- Quiescent current: 3mA
- Available packaging: TO-254, TO-3 or bare die
Applications
Power supplies for high-temperature electronic systems used in Well logging, Automotive, Aeronautics or Aerospace applications
