( Brand: Motorola ), ( Manufacturer Part Number: MC1463R ), ( Part Type: Voltage Regulator )
The MC1463R is a vintage negative voltage regulator manufactured by Motorola in 1970. This device is a critical component in electrical circuits that require a stable, regulated negative voltage supply. The MC1463R is a three-terminal regulator, with inputs for the unregulated voltage source (IN), the ground (GND), and the regulated negative output (OUT).
The MC1463R is a high-quality, linear voltage regulator that can handle input voltages ranging from 6 volts to 30 volts, and it can provide a regulated output voltage of -5.5 volts with a maximum current of 300 milliamperes. The regulator is designed to operate over a wide temperature range, from -55 degrees Celsius to 125 degrees Celsius, making it suitable for use in a variety of applications.
The MC1463R features a thermal shutdown feature that protects the regulator from overheating. When the temperature of the regulator exceeds a certain threshold, the thermal shutdown mechanism triggers, causing the regulator to stop generating output voltage until the temperature drops below the threshold. This feature helps prevent damage to the regulator and the circuit it is powering.
The MC1463R is housed in a small, compact package with a TO-92 three-lead metal can, making it easy to integrate into a circuit board. The regulator is equipped with a precision-matched zener diode that provides a stable reference voltage, ensuring a high degree of output voltage regulation.
In summary, the MC1463R is a high-performance, vintage negative voltage regulator that provides a stable, regulated negative voltage supply. Its wide input voltage range, high current capability, and thermal shutdown feature make it an ideal choice for a variety of applications, including power supplies, electronic circuits, and test equipment.
