Dagasheet what i understand then from your answer XX, These two digits of the type number indicate nominal voltage. The maximum dropout voltage Vd is 2. Output Transistor Safe-Area Compensation? An input bypass capacitor should be selected to provide good high-frequency characteristics to insure stable operation under all load conditions.

Load Regulation – The change in output voltage for a change in load current at constant chip temperature. Therefore, a four-ampere plastic power transistor is specified.

In many low current applications, compensation capacitors are not required. Home Questions Tags Users Unanswered. NCV prefix is for automotive and other applications requiring site and change control. How much higher depends on the type of regulator. So the 20V delivers 20W, while the load mc812 consumes 12W.

Even though the typical dropout voltage is 2 volts, you should use the maximum value in your design. If we look further we can see two values for line regulation; it appears that this is best if the input voltage is at least 16V.

The bypass capacitor should be mounted with the shortest possible leads directly across the regulators input terminals. Post as a guest Name.

Output Current in Excess of 1. If so, what is the current like that it outputs?

Datasheet – MC – Voltage Regulators – Motorola

In order to minimize dissipation the MCC is chosen in this application. Normally good construction techniques should be used to minimize ground loops and lead resistance drops since the regulator has no external sense lead. A is a linear regulator, and does not step up the input voltage if the input is below the output for that you need a DC-DC boost regulator.

This is a snapshot of page 8: Datashedt Term Stability – Output voltage stability under accelerated life test conditions with the maximum rated voltage listed in the devices’ electrical characteristics and maximum power dissipation.

On page 6 of the datasheet, the maximum dropout voltage Vd is listed as 2. The current sensing PNP must be able to handle the short circuit current of the three-terminal regulator. The minimum voltage obtainable with this arrangement is 2.

How does it go from a Maximum dropout voltage to a minimum input voltage? Current Boost Regulator Figure Post Your Answer Discard By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

An LDO might datsaheet a dropout voltage of 0. So you won’t find a parameter “minimum input voltage”, but it is mentioned as a condition for proper operation within certain limits.

The is a non-LDO linear regulator, which means it needs a higher input voltage. I’ve seen LDOs with a dropout voltage of 50 mV.
