Which IC is used as a positive voltage regulator?

Which IC is used as a positive voltage regulator?

LM317 voltage regulator IC can be used for producing a desired positive fixed DC voltage value of the available voltage range.

Which IC can be used as both positive and negative voltage regulator?

Nomenclature and packaging There is a related line of 79xx devices which are complementary negative voltage regulators. 78xx and 79xx ICs can be used in combination to provide positive and negative supply voltages in the same circuit.

What is the output of the IC?

The output discharge function brings the VOUT voltage to the GND level when the output of a load switch IC is disabled. When the load switch IC is disabled, the output discharge function turns on the internal MOSFET between VOUT and GND, quickly discharging the capacitor connected to the VOUT terminal.

How do I know if my AC adapter is positive or negative?

The positive wire should be the one with the white stripe, and the negative wire should be black.

Is there a positive or negative power supply for an IC?

Analog IC’s often have dual polarity supplies so their outputs can swing both positive and negative. While some may be limited to +/-5, +/-12 is probably most common still. You seem to be specific about some devices that utilize voltage only in the +/-5 volt range.

Are there analog ICs with positive and negative voltages?

Analog IC’s often have dual polarity supplies so their outputs can swing both positive and negative. While some may be limited to +/-5, +/-12 is probably most common still. You seem to be specific about some devices that utilize voltage only in the +/-5 volt range. Perhaps you could say more about the devices in question?

What should the dropout voltage of an IC regulator be?

For example if a LM7805 regulator is to provide 5V at its output, the input voltage must be no lower than 5v +2.5V =7.5V. However dropout voltage is not an absolute value, it may vary by about 1V depending on the current drawn from the output and the temperature at which the regulator is operating.

Why do I need a negative 5V power supply?

Most multiplexers have the +5V Vcc and ground (0 V) power pins but some multiplexers also have a negative -5 voltage pin for the sole purpose of enabling certain transistors within the circuit to switch faster on/off. You can look up emitter coupled logic for more details. Thanks for your response.
