The talked about circuit is allocated to handle not a lot more than 1.5amps, if higher current is needed, both the ICs could be replaced with LM338 for getting a max 5amp current or LM396 for a max of 10amp current. This really is accomplished by adjusting R4. The current managed voltage provided from the upper stage is next placed on the lower LM317 voltage regulator circuit, which allows the most wanted voltage to be set between 1.25V to 30V, here the max range getting 9V since the source is a 9V battery. The above is determined by utilizing the following formula:
LM317 ADJUSTABLE VOLTAGE REGULATOR CIRCUIT FULL
R2 is chosen to obtain a range of around 1.25A max current limit, the minimum permitted being 5mA when the full 250 ohms is placed in the path, which means the current to the laser might be set as preferred, somewhere between 5mA to 1 amp.
LM317 ADJUSTABLE VOLTAGE REGULATOR CIRCUIT SERIES
Fundamentally both the phases are attached in series for applying a total quick and easy voltage and current regulation for the linked load which can be a laser diode in the present case. The input supply source is linked across the Vin and ground of the upper current regulator circuit, the output out of this stage goes to the input of the lower LM317 variable voltage regulator stage. To be accurate the upper LM317 forms the variable current regulator stage while the lower behaves like a variable voltage controller stage.
