Circuit Adjustable Symmetrical Power Supply Using negative and positive Regulator IC’s LM317 and LM337 / +- 1.2 at 30 Volts
The circuit will serve as a voltage converter with an input voltage of 35 V to produce an output voltage of 1.25 V to 30 V. The positive voltage is being handled by LM317 IC while the negative voltage is handled by LM337. The circuit can provide an output current of 1 A. During the [...]
Circuit Power Supply regulated 7.5A @ 1.2 to 25Volts – Low Dropout Positive Adjustable Regulators LT1083
The LT1083 series of positive adjustable regulators are designed to provide 7.5A with higher efficiency than currently available devices. All internal circuitry is designed to operate down to 1V input-to-output differential and the dropout voltage is fully specifi ed as a function of load current. Dropout is guaranteed at a maximum of 1.5V at maximum [...]
