The MJ provides current to 5. 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 If so, what is the dtaasheet like that it outputs? Sign up using Facebook. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.

Values of less than 0. 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. Therefore it’s best to keep the input voltage just above the minimum to prevent the regulator to become overheated. The input voltage must be above the output. 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.
All linear regulators have a minimum dropout voltageor difference. Normally good construction techniques should be used to minimize ground loops and lead resistance drops since the regulator has no external sense lead.
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.
The datasheet does say how much it needs, but you may have to look for it. Internal Short Circuit Current Limiting? On the datasheet it doesn’t mention an input voltage.
The current to your load flows through the regulator and is the same current as will be drawn from the input voltage. The minimum voltage obtainable with this arrangement is 2. How much higher depends on the type of regulator. The bypass capacitor should be mounted with the shortest possible leads directly across the regulators input terminals. Email Required, but never shown.
This is a snapshot of page 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. Short Circuit Protection http: If you have an input voltage of 20V the same 1A will be drawn from that md7812.
Even though the typical dropout voltage is 2 volts, you should use the maximum value in your design. Representative Schematic Diagram http: Peter Mortensen 1, 3 14 The is a non-LDO linear regulator, which means it needs a higher input voltage. Although designed datssheet as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents.
Changes in VO due to heating datasehet must be taken into account separately.
Functional operation above the Recommended Operating Conditions is not implied. 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.

Internal Thermal Overload Protection? So the 20V delivers 20W, while datashet load only consumes 12W. Current Regulator Figure 9. 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.
