The LM317 is an adjustable three-terminal
positive-voltage regulator capable of supplying
more than 1.5 A over an output-voltage range of
1.2 V to 37 V. It is exceptionally easy to use and
requires only two external resistors to set the
output voltage. internal structure of it show below.
A: An lm317 is a negative 1.25v regulator
The basic function of IC 741 is amplification. It is mainly used to magnify amplify weak signals inside a circuit.
Full form of LM in any IC like LM317 is linear monolithic
IC's which starts from 7 are most of them are digital ic's . not all the IC's starts with 7 for example LM380 audio IC CTC810 audio amplifier ic and lm317 voltage regulator ic ,NE555 timer ic, 4017 counter and so other. there are no fact behind them . 7400- nand 7402 -nor 7404-not 7408-and 7432-or 7486-exor 74266-ex-nor 74147 priority encoder.
LM317 can be used for regulated dc power supply upto 37V. For more voltage range, a zener can be connected at the reference pin.
That package contains four 2-input NAND gates with Schmitt-trigger inputs.
The LM317 voltage regulator can be set to any output voltage from 1.2 V to 37 V. You must keep the input voltage between the maximum input voltage and the drop-out voltage for proper operation. The maximum input voltage the LM317 is guaranteed to bear is 40 V. The LM317 is guaranteed to operate when the input voltage is at least 3 volts above the set output voltage.
There is no Calculus function like ic 4808. Kindly check your question again.
it is ic of 78 series.its voltage is 12V
what is the function of ic UM66.plz tel me
A. Ic
IC means integrated circuit the name controller refers to its function control.
