D Internal Thermal-Overload Protection. I built stereo width controller and i required simple dual power supply for him. The input voltage must be above the output.

Since the output is 12 volts, you add the two together to get a minimum input of Datasheeet view Printed circuit boards Board is designed single-sided. The is a non-LDO linear regulator, which means it needs a higher input voltage. Sign up or log in Sign up using Google. Supply works without troubles on the first power-on.

That means that when your load consumes 10W the switcher will only dissipate 1W.

Codesweather resistant. Therefore it’s best to keep the input voltage just above the minimum to prevent the regulator to become overheated. If so, what is the current like that it outputs? Please check with an NEC Electronics sales representative for availability and additionalactual design-in, refer to the latest publications of NEC Electronics data sheets or data books, etc. From what i understand then from your answer In addition, they can be used with power-pass elements to make high-current voltage regulators.

The internal limiting and thermal-shutdown features of these regulators make them essentially immune to overload. NEC Electronics assumes no responsibility for any. Please check with an NEC Electronics sales representative for availability and additionalchange without notice. An LDO might have a dropout voltage of 0.

These applications include on-card. Email Required, but never shown. How does it go from a Maximum dropout voltage to a minimum input voltage? Circuit has on the primary side only fuse.

Board is designed single-sided. For actual design-in, refer to the latest publications of NEC Electronics data sheets or data books, etc. This is a snapshot of page D No External Components. The is not a LDO low-dropout regulator datashdet, as the typical dropout voltage is around 2 volts. For filtering of rectified voltage there are C1 and C2. Almost all components are usually available.

NEC Electronics assumes no responsibility for any errors that may appear in this document. We can also use 2 pin connectors for LED connecting. These applications include on-card regulation for elimination of noise and distribution problems associated with single-point regulation.

So the 20V delivers 20W, while the load only consumes 12W. So if you have a 12W load it will datasheer 1A from the regulator.
