Published:2011/4/14 3:39:00 Author:Nicole | Keyword: Power supply, TTL | From:SeekIC

This circuit can be used to provide TTL integrated circuit with power supply. Potentiometer Rp =1kΩ is used to adjust output voltage, normally, it is 5V. The regulator tube is used to provide reference voltage. The main technical details: input voltage: U1=220±10%V, 50Hz; output voltage: U2=5V; adjustable range of output voltage: 0.7~7V; the max output current:I2=2A; noise voltage: U<2mV; transformer turns: n1=1550 turns, 0.25mm enameled copper wire, n2=72 turns, 1.4mm enameled copper wire.
