Pinout
The LM117HVH is a high-voltage version of the LM117 voltage regulator. It typically comes in a TO-3 package and has a 3-pin configuration. Here is a brief overview of its pin functions:
1. Input (Pin 1): This pin is where the unregulated input voltage is supplied. It is connected to the collector of the internal pass transistor and should be higher than the desired output voltage by a certain margin to ensure proper regulation.
2. Output (Pin 2): This pin provides the regulated output voltage. The voltage is adjustable and determined by external resistors connected between the output, adjustment, and ground.
3. Adjustment (Pin 3): This pin is used to set the output voltage. By connecting a resistor between this pin and the output, and another between this pin and ground, the output voltage can be adjusted according to the ratio of these resistors.
The LM117HVH is designed for high-voltage applications, capable of handling input voltages up to 60V, and providing a stable, reliable output with a precision of ±1%.
