So you won’t find a parameter “minimum input voltage”, but it is mentioned as a condition for proper operation within certain limits.
Values of less than 0. Current Boost Regulator Figure Home Questions Tags Users Unanswered. Load Regulation – The change in output voltage for a change in load current at constant chip temperature.

This is a snapshot of page However, it is recommended that the regulator input xatasheet bypassed with a capacitor if the regulator is connected to the power supply catasheet with long wire lengths, or if the output load capacitance is large. Normally good construction techniques should be used to minimize ground loops and lead resistance drops since the regulator has no external sense lead.
But since there’s this voltage drop the input voltage has to be higher than the output voltage.
Even though the typical dropout voltage is 2 volts, you should use the maximum value in your design. That means that when your load consumes 10W the switcher will only dissipate 1W. Sign up using Email and Password. Voltage regulators basically can be divided in two big groups: If you have an input voltage of 20V the same 1A will be drawn from that 20V.
The current sensing PNP must be able to handle the short circuit current of the three-terminal regulator. 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.
On the datasheet it doesn’t mention an input voltage. Functional operation above the Recommended Operating Conditions is not implied. An LDO might have a dropout voltage of 0.
The bypass capacitor should be mounted with the shortest possible leads directly across the regulators input terminals. 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.
In datasheeh to minimize dissipation the MCC is chosen in this application.
minimum input voltage? – Electrical Engineering Stack Exchange
So if you have a 12W load it will draw 1A from the regulator. NCV prefix is for automotive and other applications requiring site and change control. The minimum voltage obtainable with this arrangement is 2.
Therefore, a four-ampere plastic power transistor is specified. Maximum Dtasheet Dissipation – The maximum total device dissipation for which the regulator will operate within specifications. Email Required, but never shown. The circuit of Figure 10 can be modified to provide supply protection against short circuits by adding a short circuit datashert resistor, RSC, and an additional PNP transistor.
The datasheet does say how much it needs, but you may have to look for it. Load and line regulation are specified at constant junction temperature.
