Even though the typical dropout voltage is 2 volts, you should use the maximum value in your design. Stresses exceeding Maximum Ratings may damage the device.

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 where personal injury or death may occur. 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. 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.
Pulse testing with low duty cycle is used. Sign up using Email and Password. I’ve seen LDOs with a dropout voltage of 50 mV.
Output Noise Voltage – The rms ac voltage at the output, with constant load and no input ripple, measured over a specified frequency range.
The maximum dropout voltage Dataasheet is 2. On the datasheet it doesn’t mention an input voltage. Changes in VO due to heating effects must be taken into account separately. The bypass capacitor should be mounted with the shortest possible leads directly across the regulators input terminals.
The difference of 8W will be dissipated in datashset regulator. They mc77812 like a variable series resistor between input and output, causing a voltage dafasheet across the regulator. 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, costs, 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 of the part.
Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. In order to minimize dissipation the MCC is chosen in this application.
Output Current in Excess of 1. Maximum Power Dissipation – The maximum total device dissipation for which the regulator will datasheer within specifications. Therefore, a four-ampere plastic power transistor is specified. The MJ provides current to 5.

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.
Therefore it’s best to keep the input voltage just above the minimum to prevent the regulator to become overheated.
Dean 4, 22 57 Values of less than 0. Home Questions Tags Users Unanswered. These regulators employ internal current limiting, thermal shutdown, and safe-area compensation. Sign up using Facebook. Short Circuit Protection http: Load Regulation – The change in output voltage for a change in load current at constant chip temperature. SCILLC makes no warranty, representation or guarantee regarding the suitability of its products for any particular purpose, nor does SCILLC assume any liability arising out of the application or use of any product or circuit, and specifically disclaims any and all liability, including without limitation special, consequential or incidental damages.
So the 20V delivers 20W, while the load only consumes 12W. A note on dissipation: Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents.

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. Linear mc7182 are different.
