The Form Fit Function (FFF) tab will give you the options that are more likely to serve as direct pin-to-pin alternates or drop-in parts. The Functional Equivalents tab will give you options that are likely to match the same function of LM111D, but it may not fit your design. Always verify details of parts you are evaluating, as these parts are offered as suggestions for what you are looking for and are not guaranteed.
LM111D Frequently Asked Questions (FAQ)
-
The maximum power dissipation of the LM111D is dependent on the package type and ambient temperature. For the DIP package, it is 1.5W at 25°C, and for the SO8 package, it is 1.3W at 25°C.
-
To ensure stability in the LM111D voltage regulator, it is recommended to use a minimum output capacitance of 10uF, and to keep the distance between the regulator and the capacitor as short as possible. Additionally, the output capacitor should have a low ESR (Equivalent Series Resistance) to prevent oscillations.
-
Yes, the LM111D can be used as a variable voltage regulator by connecting a resistive divider network between the output and the adjust pin. The output voltage can be adjusted by varying the resistance ratio of the divider network.
-
The minimum input voltage required for the LM111D to operate is 3V, but it is recommended to use a minimum input voltage of 4.5V to ensure proper regulation and to prevent dropout.
-
To protect the LM111D from input voltage transients, it is recommended to use a transient voltage suppressor (TVS) diode or a zener diode in parallel with the input capacitor. This will help to clamp the input voltage and prevent damage to the regulator.
