Dual adjustable power supply circuit with a diagram using IC LM317 and LM337. This variable power supply circuit has a range of 1.2 volts to 30 volts.
The dual adjustable power supply circuit utilizes the LM317 and LM337 voltage regulators to...
Variable Power Supply
Using the versatile L200 voltage regulator, this power supply has independent voltage and current limits. The mains transformer has a 12-volt, 2 amp rated secondary, the primary winding should equal the electricity supply in your country, which is 240V here...
LM317 Voltage Regulator
The LM317T is a widely used positive voltage regulator, forming the basis for many laboratory power supplies and other equipment. It can output a voltage ranging from 1.25V to 35V by adjusting the resistance between its adjustment pin and ground....
Mobile voltage regulator
This simple mobile voltage regulator circuit may save your two-meter or CB transceiver if the voltage regulator fails. The 2N3055 should be heat-sinked if the current drawn by the rig exceeds 2 A during transmission. This circuit will do little...
Low Ohms Adaptor For DMMs Based On An LM317 Regulator
This adapter circuit functions as a 100mA constant current source. It is connected across a low-value resistor, the resistance of which is to be measured, and the resulting voltage drop can then be assessed using a digital multimeter (DMM). Setting...
UNIVERSAL BATTERY CHARGER
When power is applied to the circuit, SCR1 remains off, resulting in no bias-current path to ground; consequently, the LM317 operates as a current regulator. The LM317 is connected to the battery through steering diode D1, limiting resistor R1, and...
12-16V-converter
Many devices operate from a car's 12-V electrical system. Some require 12 V, while others need a lower voltage. An automobile battery's output can vary from 12 to 13.8 V under normal circumstances. The load requirements of the device may...
