Pinout
The LM1084IS-ADJ is a low-dropout (LDO) linear voltage regulator. It typically comes in a TO-263 or TO-220 package with three pins. The pin configuration is as follows:
1. Adjust (Adj): This pin is used to adjust the output voltage. By connecting a resistor divider network between the output and this pin, users can set the desired output voltage.
2. Output (Out): This pin provides the regulated output voltage. The voltage is adjustable between 1.25V and the maximum input voltage minus the dropout voltage, depending on the resistor configuration.
3. Input (In): This pin receives the input voltage, which should be higher than the desired output voltage by at least the dropout voltage to maintain regulation.
The LM1084IS-ADJ is capable of delivering up to 5A of output current, making it suitable for high-current applications. It is commonly used in applications requiring adjustable and precise voltage regulation.
