Linear regulators are different. Normally good construction techniques datasjeet be used to minimize ground loops and lead resistance drops since the regulator has no external sense lead. For example, a 1.

Changes in VO due to heating effects must be taken into account separately. Sign up using Facebook.

MC Datasheet(PDF) – Fairchild Semiconductor

From the above it may look like you best make your input voltage a lot higher than the 12V output, but that’s not true. The MJ provides current to 5. On page 6 of the datasheet, the maximum dropout voltage Vd is listed as 2. Home Questions Tags Users Unanswered. Output Noise Voltage – The rms ac voltage at the output, with constant load and no input ripple, measured over a specified frequency range.

These regulators employ internal current limiting, thermal shutdown, and safe-area compensation. Resistor R determines the current as dztasheet The input voltage must remain typically 2. Resistor R in conjunction with the VBE of the PNP determines when the pass transistor begins conducting; this circuit is not short circuit proof.

Post as a guest Name.

So the 20V delivers 20W, while the load only consumes 12W. From what i understand then from your answer Even though the typical dropout voltage is 2 volts, you should use the maximum value in your design.

They are like a variable series resistor between input and output, causing a voltage drop across the regulator. However, it is recommended that the regulator input be bypassed with a capacitor if the regulator is connected to the power supply filter with long wire lengths, or if the output load capacitance is large.

But since there’s this voltage drop the input voltage has to be higher than the output voltage. The maximum dropout voltage Vd is 2. Therefore, a four-ampere plastic power transistor is specified. Representative Schematic Diagram http: This is a snapshot of page 8: If so, what is the current like that it outputs?


SCILLC products are not designed, intended, or authorized for use as components in systems intended for surgical implant into the body, or other applications intended to support or sustain life, or for any other application in which the failure of the SCILLC product could create a situation datashet personal injury or death may occur.

An LDO might have a dropout voltage of 0. Load and line regulation are specified at constant junction temperature.

Internal Short Circuit Current Limiting? Internal Thermal Overload Protection?

How does it go from a Maximum dropout voltage to a minimum input voltage? Maximum Power Dissipation – The maximum total device dissipation for which the regulator will operate within specifications. Although designed mc782 as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents.
