What is LM317 transistor?

What is LM317 transistor?

The LM317 device is an adjustable three-terminal positive-voltage regulator capable of supplying more than 1.5 A over an output-voltage range of 1.25 V to 37 V. It requires only two external resistors to set the output voltage. The device features a typical line regulation of 0.01% and typical load regulation of 0.1%.

What is line regulation of voltage regulator?

Line regulation is the ability of a power supply to maintain a constant output voltage despite changes to the input voltage, with the output current drawn from the power supply remaining constant. where ΔVi is the change in input voltage while ΔVo is the corresponding change in output voltage.

What is then the LM317 IC is all about?

The LM317T is an adjustable 3-terminal positive voltage regulator capable of supplying different DC voltage outputs other than the fixed voltage power supply of +5 or +12 volts, or as a variable output voltage from a few volts up to some maximum value all with currents of about 1.5 amperes.

What is lm358n IC?

The LM158 series consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages.

What is the difference between line regulation and load regulation?

Line regulation is the change in output voltage due to a specified change in input voltage, normally quoted in microvolts per volt. Load regulation is a similar change due to a change in load current, expressed either in percent for a given current change or as a dynamic resistance in ohms.

What is the output voltage of a lm338 regulator?

The LM138 and LM338 devices are adjustable, three-terminal, positive-voltage regulators capable of supplying more than 5 A over an output-voltage range of 1.2 V to 32 V. It requires only two external resistors to set the output voltage.

What are the characteristics of the lm138/lm238/lm338?

The LM138/LM238/LM338 are adjustable 3-terminal positive voltage regulators capable of supplying in excess of 5A over a 1.2V to 32V output range. They are exceptionally easy to use and require only 2 resistors to set the output voltage.

How to install IC lm338k in PCB?

The output voltage at the output pin of the IC1 is a more powerful filter with the capacitor C3. You must solder all devices in the PCB to completely, for the IC LM338K should install with a large heat sink. and all device has the poles.

What is the output discharge on the lm138?

The Discharge occurs when either the input or output is shorted. Internal to the LM138 is a 50X resistor. which limits the peak discharge current. No protection is needed for output voltages of 25V or less and 10 mF capacitance.
