CHT-LD-100 Datasheet | Cissoid

Features General Description The CHT-LD-100 is a 1A, low-dropout linear voltage regulator patible with high-temperature environments. Typical operation temperature range extends from -30°C to 225°C. 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 100m A. The input voltage may span from 11 Volts to 25 Volts. The circuit is a one-die solution. CHT-LD-100 is available in die and packages (currently TO-3 and TO-220) on demand. - - - - - - - - - - 11V to 25V input Voltage @100m A 12V to 25V input Voltage @1A Max 1A output current @ 225°C 60d B input ripple rejection (0-100Hz) Cload from 100n F to 1000µF, large ESR range Available on die or in custom package on demand.
