regulator

Hello, I am trying to make supply which can output 48V and 1A current. I found out that LM723 can output 48V if used in floating state. The things is that I calculated everything but when I use the same value Rz resistor which is in the datasheet of 2kOhms my output drops to 45V. But when I...

I am a beginner about electronic circuits and english I am designing a circuit to use two three-terminal regulators L78S05CV (5V2A) to cover the power supply of Raspberry Pi Zero 2 W, because 5V 2.5A is recommended. However, many sources say that the maximum measured current consumption of the...

Hi, I have a problem, In the following circuit, I have a voltage regulator with a selector that chooses between different resistor values to make different voltages. But if ever the selector malfunctions or when changing, it will be disconnected, so the circuit will be open and the voltage...

"Hello everyone, I'm new to the field of PCB design. I'm working on a circuit to recharge a Li-ion battery. I want to charge this battery with a voltage of 4.1V and 3A. I want to use the MP2393GTL-Z regulator for this. My input voltage source is a stabilized power supply that provides 24V. Below...

I am designing a constant 5 volt output switching regulator that bucks 12 to 24 volts down to 5 volts while supporting 5 amps. It is used to boot up a Raspberry Pi with a 10 inch screen. At 12 volts, the Pi will boot up fine. At 24 volts, around halfway through the bootup, the regulator will...

Hey all, I'm looking for a DC-DC Buck which can supply 12V output with 40A while taking an input of 18V/24V. Is there any such part available in the market? Need help.

Hi everyone, I need a 5.0V-3.3V for 2-2.5A load consumption, do I need a switching regulator or LDO just fine? I prefer the simplification of LDO design but am not sure if 2-2.5A load current needs better efficiency from a buck regulator. Thank you,

Hello everyone, I got an old motorcycle (Sachs 125cc) and I need to fix my front headlights, because their lighting isn't powerful enough. I am not using a battery for them and they only work with the dynamo. As a result when I hit the gas the headlights shine enough and I want to keep that...

Hi, In the below circuit I would like to know how to determine the the resistance(R9) and capacitance(C6) value ? This circuit is a IOT based fan controller. Here we are using 240VAC, Even though they have shown the values I am interested in knowing how to design a RC snubber circuit for a fan...

I am using Arduino and Controlling FAN which works on 48v. so i am using 2 power supply smps in my design. One for Arduino that 5V smps and another for FAN that is 48V smps. I want to use single power supply in my design that is of 48Vdc. I was looking for a buck converter that will take 48V as...

Hello, I need Some help, if its possible Problem Description: I've Got Ceiling Speakers Pair (150 Watt each, Max). It has Some Amplifier in box, with only AUX (3.5 mm) audio port and Bluetooth option. It has no volume regulator or anything else. (model No. AMP-BTX 01) I've Mounted it in Ceiling...

Here a shunt voltage regulator circuit with two zener diodes One zener diode Z give the reference voltage at the comparator for the feedback signal . But I can't explain the role of the second zener diode Z1 I've to calculate Voltage Stability factor (Sv) . Any Suggestion is welcome.

Hello, I am fairly new to electronics design (I have a mech e background), and am designing a board that requires dropping 12v to 5v with a large current requirement (up to 8A@5V). In a bid to save on BOM, I took a shot at creating my own design vs buying one off the shelf, using the...

I have built an op-amp series pass voltage regulator, whose output is inputted into an analog-to-digital converter (ADC0804). The ADC's output is connected to a CoolRunner II CPLD Starter Board. This output corresponds to a value on a look-up table, which determines what value would be displayed...
