RIGEL: High Temperature Adjustable 100mA Voltage Regulator

RIGEL: High Temperature Adjustable 100mA Voltage Regulator

The CHT-RIGEL is a high-temperature, high-reliability, 100mA adjustable linear voltage regulator suitable to generate any regulated voltage in the range +0.9V to +28V  from a standard +4.5 to 30V source.  Its typical operation junction temperature ranges from -55°C to +225°C, though it can exceed that range with some performance de-rating.

The regulator is self-protected with a built-in over-current limitation and thermal protection which is effective in the range +250°C to +300°C.

CHT-RIGEL brings unique benefits in applications where the ambient or operating temperature is above the temperature supported by traditional semiconductors, or in applications that operate at +155°C but require extended reliability.

The IC features a chip-enable (CE active low) input signal allowing placing the circuit in low-power, disable mode. The output voltage is adjustable by the external resistive feedback.

The CHT-RIGEL is a one-die solution, available in a tiny ceramic package TDFP-16 for applications where small PCB foot-print is critical.
