NOTE: The gate voltage need to trigger the MOSFET is 10v with a 1A current LM723 MOSFET power supply LM723 MOSFET power supply A few useful application circuits using IC LM317. The configurations can be introduced for different applications for upgrading an existing unit with features that would virtually make it indestructible. The BC547 transistor and resistor are for protecting the short circuit. LM317 constant current source is one of the simplest design.Its really simple, you can build the circuit on a bread board or just by soldering components to each other.But that will add another voltage drop of around 0.7 V to 1 V, so I excluded it.But you cant find a 12.5 Ohm, 6.25 Ohm or 1.25 Ohm resistor for 100 mA, 200 mA and 1 Amp current respectively. The IC LM317 is so versatile that an almost unlimited number of different, small, high grade power supply circuits can be built using it. The current boosting is the duty of the MOSFET in this circuit, the resistor adjusts to the MOSFET will provide gate voltage to trigger the MOSFET. The circuit shows the power supply using LM317 and MOSFET, the LM317 is the most popular voltage regulator IC which can have a voltage range of (0 to 24v) and a current limit of (1.5A). LM317 MOSFET power supply LM317 MOSFET power supply Multiple conversion circuit sections are been used mostly on the switched-mode power supplies and at Arduino projects, so the power generation from the pulsed signal is the main purpose of the MOSFET power supply. In todayвЂ™s post, weвЂ™ll discuss an IC LM338 circuit based on its characteristics, applications, pin. However, LM317 has a lower current than LM338. LM338 application circuit is similar to LM350 or LM317 in terms of easy usage and few components. The PWM MOSFET power supply setup is used to convert the pulsed signal from the PWM section into a voltage output. An LM338 integrated circuit is part of the LM-series ICs made by the National semiconductor.
