Package
The LM1086IS-5.0 is a fixed voltage regulator with a TO-263 package type. The TO-263 package, also known as D2PAK, is a surface-mount package that is designed for high-power applications and features a flat, thermally effective design suitable for efficient heat dissipation.
Pinout
The LM1086IS-5.0 is a low dropout voltage regulator. It typically comes in a TO-263 package and features 3 pins. The pin configuration and functions are as follows:
1. Pin 1 (Input): This is the input pin where the unregulated DC voltage is applied. The input voltage must be higher than the desired output voltage for proper regulation.
2. Pin 2 (Ground): This is the ground reference pin. It is connected to the ground or negative side of the input and output voltages.
3. Pin 3 (Output): This pin provides the regulated output voltage, which is fixed at 5.0V for the LM1086IS-5.0 version.
The LM1086 series is designed to provide a stable output voltage with a dropout voltage of approximately 1.5V at full load, making it suitable for applications where input voltage is close to the output voltage.
