Power Dissipation for LDO

Enter the Input Voltage, Output Voltage and Output Current and press "Calculate" to solve for the other and find the Dissipation for LDO (Low Drop-Out).


Input Voltage value: volts
Output Voltage value: volts
Output Current value: Amps


Output Power value: watts
Input Current value: Amps
Input Power value: watts
Power Dissipation: watts
Current Consumption: Amps

For an Example, The Input Voltage is 5V, Output Voltage is 3.3V 1A. The Difference between Input and Output Power will be Dissipation.The Output will be 3.3V * 1A = 3.3W. In the case of LDO(Low Drop-Out), Input and Output Current will be same.

The Power Dissipation will happen because of Difference between Input and Output Voltage, then the Input Power will be 5V * 1A =5.0W.The Difference between the Output power and the Input Power is the what we are looking for, which in ths example is 5 - 3.3 = 1.7W.
