Package

The LM350T/NOPB is a three-terminal adjustable voltage regulator packaged in a TO-220 form factor. This package type is suitable for through-hole mounting and provides good thermal performance, making it ideal for applications requiring moderate power dissipation.

Pinout

The LM350T/NOPB is a 3-pin adjustable voltage regulator. It is designed to provide an output voltage range of 1.25V to 33V, with a current output capability of up to 3A. The three pins are:
1. Input (Vin): This pin is where the unregulated input voltage is supplied. It should be higher than the desired output voltage and within the specified limits to ensure proper operation.
2. Output (Vout): This pin provides the regulated output voltage. The voltage is set by using a pair of external resistors connected between the output, the adjustment pin, and ground.
3. Adjustment (Adj): This pin is used to adjust the output voltage. By connecting it to a resistor divider network between the output and ground, the output voltage can be set to the desired level.
The LM350T/NOPB is commonly used in applications requiring a stable and adjustable power supply, such as power supplies for electronic devices and systems requiring a specific voltage level.
