NettetTo analyze the loop stability of linear regulators, we will start with the standard NPN regulator as an example. There are two poles in the standard NPN regulator -- a dominant pole (P INT), created by the intrinsic capacitance of the regulator, and a power pole (P PWR), created by the pass element. P INT and P PWR occur at the following ... Nettet7. okt. 2024 · You're using a linear regulator which simply "burns off" the excess voltage.. The current does not change and remains the same so you can draw up to 1.25 A at the output of the regulator. So after the regulator you're limited to 5 V, 1.25 A so 6.25 W. When you draw that 6.25 W there is 12 V - 5 V = 7 V at 1.25 A meaning 7 V * 1.25 A = …

"Nettet18. sep. 2024 · A linear voltage regulator is also called a step-down converter where the output voltage is always less than the input voltage. It consumes some of the power and converts it into heat in order to generate a constant output voltage. Linear voltage regulators normally consist of three pins: the Input pin, Output pin, and Ground pin. " - Linear regulator wikipedia
