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 cm7812 where personal injury or death may occur.

If you have an input voltage of 20V the same 1A will be drawn from that 20V. This is a snapshot of page Stresses exceeding Maximum Ratings may damage the device. Sign up using Email and Password. There are LDOs Low Drop-Out which still can regulate the output if the input is only a few hundreds of mV higher and there are even ultra low drop-out types which only need a few tens of mV. Values of less than 0. On the datasheet it doesn’t mention an input voltage.

Voltage regulators basically can be divided in two big groups: The is not a LDO low-dropout regulatoras the typical dropout voltage is around 2 volts. All linear regulators have a minimum dropout voltageor difference. Post as a guest Name. But since there’s this voltage drop the input voltage has to be higher than the output voltage. Therefore, a four-ampere plastic power transistor is specified. That means that when your load consumes 10W the switcher will only dissipate 1W.
Peter Mortensen 1, 3 14 NCV prefix is for automotive and other applications requiring datashee and change control. Pulse testing with low duty cycle is used.
XX, These two digits of the type number indicate nominal voltage. If so, what is the current like that it outputs? In order to minimize dissipation the MCC is chosen in this application. 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.
Load Regulation – The change in output voltage for a change in load current at constant chip temperature. The bypass capacitor should be mounted with the shortest possible leads directly across the cm7812 input terminals.
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.
So you won’t find a parameter “minimum input voltage”, but it is mentioned as a datasjeet for proper operation within certain limits. Resistor R in conjunction with the VBE of the PNP determines when the pass transistor begins conducting; this circuit is not short circuit proof. Sign up using Facebook.
So the 20V delivers 20W, while the load only consumes 12W. An LDO might have a dropout voltage of 0.

The measurement is made under conditions of low dissipation or by using pulse techniques such that the average chip datashfet is not significantly affected. Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents. Maximum Ratings are stress ratings only.

Maximum Power Dissipation – The maximum total device dissipation for which the regulator will operate within specifications.
