The CHT-LDOS is a 1A, low-dropout linear voltage regulator compatible with hightemperature environments. Typical operation temperature range extends from -55°C to 225°C.
The circuit is stable throughout the whole temperature range and under a large choice of capacitive loads.
The minimum dropout voltage (Vin-Vout) is 2V with a 1A load current at 225°C and 1V for load currents lower than 400mA. The dropout voltage can span from 1 Volts to 20 Volts.
The circuit is a one-die solution. CHT-LDOS is available in TO-254 package.
