Pinout
The LT1083CP#PBF is a low dropout (LDO) positive linear voltage regulator. It typically comes in a TO-220 package and features three pins. Here is the pin count and function:
1. Pin 1 - Adjust (Adj): This pin is used to set the output voltage. By connecting a resistor divider network between the output and ground, the desired output voltage can be set.
2. Pin 2 - Output (Vout): This pin provides the regulated output voltage. It is where the load is connected, and the output voltage is set according to the configuration of the adjust pin.
3. Pin 3 - Input (Vin): This pin is where the unregulated input voltage is applied. The dropout voltage is low, which means the input voltage needs to be only slightly higher than the desired output voltage.
The LT1083CP#PBF is designed to provide high current output (up to 7.5A), low dropout voltage, and good thermal stability, making it suitable for applications where space and power efficiency are crucial.
