Dear All,
This is abt LM338 but I don't see any related thread so thought of posting a new one.
I want to use this as a voltage regulator.. so connected it to a power supply of 15.75v and Vout 3.70v ( @ R1=100 & R2=180 ). But when Vin=17.75v Vout=4.63v and Vin=20.3v Vout=8.20 ( @ same resistor values ) . I think @ fixed resistor values Vout should be the same regardless of Vin.
Can some explain me why it is not ?
Thx.
