In many low current applications, compensation capacitors are not required. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and datashwet policyand that your continued use of the website is subject to these policies.

The minimum voltage obtainable with this arrangement is 2. Linear regulators are different.

Therefore, a four-ampere plastic power transistor is specified. So the 20V delivers 20W, while the load only consumes 12W.

Sign up or log in Sign up using Google. For example, datashret 1. Since the output is 12 volts, you add the two together to get a minimum input of The is a non-LDO linear regulator, which means it needs a higher input voltage. The bypass capacitor should be mounted with the shortest possible leads directly across the regulators input terminals.

They are like a variable series resistor between input and output, causing a voltage drop across the regulator. In order to minimize dissipation the MCC is chosen in this application.

Post as a guest Name. Therefore it’s best to keep the input voltage just above the minimum to prevent datasheeet regulator to become overheated. The datasheet datasehet say how much it needs, but you may have to look for it.


Values of less than 0. With adequate heatsinking they can deliver output currents in excess of 1. Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents. An LDO might have a dropout voltage of 0. The input voltage must be above the output. A note on dissipation: Voltage regulators basically can be divided in two big groups: Maximum Power Dissipation – The maximum total device dissipation for which the regulator will operate within specifications.

If so, what is the current like that it outputs? All parameters are specified under certain conditions, and for the output voltage we can see that the condition is that the input voltage is minimum Internal Thermal Overload Protection? Long 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.

How does it go from a Maximum dropout voltage to a minimum input voltage? Should Buyer purchase or use SCILLC products for any such unintended or unauthorized application, Buyer shall indemnify and hold SCILLC and its officers, employees, subsidiaries, affiliates, and distributors harmless against all claims, datqsheet, damages, and expenses, and reasonable attorney fees arising out of, directly or indirectly, any claim of personal injury or death associated with such unintended or unauthorized use, even if such claim alleges that SCILLC was negligent regarding the design or manufacture dafasheet the part.

Email Required, but never shown.

This is a snapshot of page 8: Even though the typical dropout voltage is 2 volts, you should use the maximum value in your design. Pulse testing with low duty cycle is used.

On the datasheet it doesn’t mention an input voltage. Changes in VO due to heating effects must be taken into account separately.


These regulators employ internal current limiting, thermal shutdown, and safe-area compensation. XX, These two digits of the type number indicate nominal voltage.

A control element will vary the resistance in practice a transistor so that the output voltage will remain constant regardless of input voltage and load. 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. Functional operation above the Recommended Operating Conditions is not implied. This is a snapshot of page Current Boost Regulator Figure If you have an input voltage of 20V the same 1A will be drawn from that 20V.

No External Components Required? The circuit of Figure 10 can be modified to provide supply protection against short circuits by adding a short circuit sense resistor, RSC, and an additional PNP transistor.

The difference of 8W will be dissipated in the regulator.
