Dual Adjustable Power Supply Circuit Description This is the circuit diagram of a dual adjustable power supply using IC’s LM 317 & LM 337.LM 317 is able to deliver a maximum of 1.5 A at a range of 1.2 V to +30V .LM 337 is the negative complement of LM317.They also have a built in short circuit protection. Here the circuit is wired to produce a dual adjustable output of ( +15 , 0 , -15 ).The capacitors C1 to C8 provides filtering and ripple rejection.Resistors R1 & R2 controls output of LM 317.Resistors R3 & R4 controls the output…

Adjustable/Variable Voltage Regulator using LM 117 Description This is the circuit diagram of a 1.2 V to 25 Volts adjustable voltage regulator using IC LM 117 IC.The LM117 series of adjustable 3-terminal positive voltage regulators are able to provide in excess of 0.5A over a 1.2V to 37V output range. They are very easy to handle and require only two external resistors to set the output voltage. This power supply is able to deliver a maximum of 0.5 A current.The circuit is easy to assemble and provides great results.Resistances R1 and R2 are used for voltage adjustment.Vary pot R2 to…
