Description

The Helios CHT-LDOP high temperature, low-dropout linear voltage regulator series from Cissoid offers an output voltage range between 2.5V and 15V. These voltage regulators are compatible with high temperature environments with a typical operation temperature range from -55°C to +225°C. The LDOP series from Cissoid has a minimum dropout voltage of 1V  for load currents lower than 400mA and 2V with a 1A load current at +225°C, with a total accuracy of ±2% and a maximum output voltage  temperature drift of 80ppm.

  • High temperature, low-dropout linear voltage regulator
  • Voltage reference values of 2.5V, 3.3V, 5V, 5.5V, 5.6V, 7.5V, 9V, 10V, 12V, 13V and 15V
  • Dropout voltage of 1V to 20V at lower than 400mA
  • Dropout voltage of 2V to 20V at 1A
  • Quiescent current consumption of 3mA
  • Maximum output current of 1A at 225°C
  • Total accuracy of ±2%
  • Typical operating temperature range −55°C to +225°C (operational up to 300°C)
  • Maximum drift with temperature 80ppm
  • Validated at +225°C for 43800 hours (and still on-going)
  • Available in TO-254 package and bare die available on request

Typical Applications for the CHT-LDOP series from Cissoid include:

  • Well logging
  • Automotive
  • Aeronautics
  • Aerospace

The below table gives the full specifications of the Cissoid CHT-LDOP series:

Cissoid CHT-LDOP Specifications

1. The maximum input voltage Vin is Vout +20V or 30V, whichever is less

2. Above +225°C (Tj), a minimum load current of few mA could be required

3. Max power dissipation depends on packaging

4. ppm are defined as 1e-6x[d(Vout)/d(T)]/Vout. For a nominal output of 15V, 40ppm corresponds to 600µV/°C

5. Defining “x” as the nominal voltage, the line regulation is better than x/5 mV/V

6. This includes the packaging parasitic resistance for TO-254 packages

7. Defining “x” as the nominal voltage, the typical quiescent current at 2V dropout can be approximated as 2.95+x/13 in mA @ -55°C and 2.65+x/13 in mA at 225°C
