MOSFET Drain–Gate RD from Iout Calculator

Calculate the required drain resistor \(R_D\) from the desired output voltage and current.

Step 1: Enter Circuit Parameters

Supply Voltage, \(V_{DD}\) (V)

Example: 5 V

Desired Output Voltage, \(V_{out}\) (V)

Example: 3 V (must be less than \(V_{DD}\))

Output Current, \(I_{out}\) (A)

Example: \(1 \times 10^{-3}\) A (1 mA)
