CISSOID The SOI design Specialists CHT-LD-100 Preliminary datasheet Version 0.0 (09/2004) High-Temperature, 10V, 1A, Low-Dropout SOI-CMOS Voltage Regulator. Features General Description The CHT-LD-100 is a 1A, low-dropout linear voltage regulator compatible with high-temperature environments. Typical operation temperature range extends from -30°C to 225°C. • 11V to 25V input Voltage @100mA • 12V to 25V input Voltage @1A • Max 1A output current @ 225°C • 60dB input ripple rejection (0-100Hz) The circuit is stable throughout the whole temperature range and with a large choice of capacitive loads. The minimum dropout voltage is 2V with a 1A load and 1V for load currents lower than 100mA. The input voltage may span from 11 Volts to 25 Volts. The circuit is a one-die solution. • Cload from 100nF to 1000µF, large ESR range • Available on die or in custom package on demand. (3-pins compatible) • Stand-by mode available. (4-pins) • Tungsten interconnects for long-term reliability CHT-LD-100 is available in die and packages (currently TO-3 and TO-220) on demand. • The start-up is operative over the whole temperature range • Latch-up free Applications Power supplies for high-temperature electronic systems used in Well logging, Automotive, Aeronautics or Aerospace applications.
