About this product


Product overview

  • Monolithic IC for adjustable current and voltage regulation
  • Current and power limiting thermal shutdown and input over voltage protection up to 60V
  • Straight pins for vertical PCB mounting

A monolithic IC for adjustable voltage (up to 36V) and current (up to 2A) regulation. It has current and power limiting thermal shutdown and input over voltage protection up to 60V. The device can be used to replace fixed voltage regulators where high output-voltage precision is required, eliminating the need to stock a range of fixed voltage regulators.Type L200CV has straight pins for vertical mounting onto a PCB.


DC input voltage: 40V max.
Peak input voltage: 60V max. for 10ms
Output voltage range: 2.85 to 36V
Output current range: 0.1A to 2A
Quiescent current: 4.2mA
Load regulation: 0.15% 2A
Line regulation: 60dB
Supply voltage regulation: 60dB 100Hz
Dropout voltage between pins 1 & 5: 2V typical
Output noise: 80µV
Reference voltage (pin 4): 2.77V

What heatsink do I require for the LC200CV. I will be drawing about 300 ma

Asked by: Julian
Unfortunately, I do not know what would be needed when drawing 300ma.

Does this product enable step up in voltage?

Asked by: Stu2411
No, I am sorry but this will not step up voltage.

Hi please can you tell me is this item suitable to run 12v in and 7v out , To power the guages on my honda gold wing, how do you adjust the  final output voltage. If its not suitable can you recommend another  way to acheive this. Cheers.

Asked by: dmc1
That power adjustment is within the maximum tolerances, details on how to adjust the voltage can be found on the datasheet here;

As a follow up to my earlier question can you tell me how the voltage output is adjusted?

Asked by: Andyv
Output voltage is determined by the value of the resistors connected between pin 3 & pin 4 and pin 4 & pin 2 of the device. The final output voltage can be approximated by the expression: Vo = Vref(1+(R2 / R1)) Where: Vo = Output Voltage (V) Vref = Reference voltage on pin 4 (V) R1 = Resistance between pin 4 & pin 3 (Ω) R2 = Resistance between pin 2 & pin 4 (Ω). I have sent a full datasheet for the product to your email address This gives examples of how you would use the product in circuit, to determine the outputs.

I'm looking for device to produce a stabilised voltage for a fuel gauge, but am unsure what voltage it needs to be set at. It needs between 5 and 12 volts and around 1.5 amps. Will this device do it and how is it adjusted?

Asked by: Andyv
Thanks. I understand you can't advise on a particular installation, but can you answer my query on how the output voltage is adjusted. Is there a screw to turn or does it need additional components?

Dear sir i,am trying to replace a 317K variable voltage regulator which I used in a power supply I built 20 years ago ,possibly from a diagram in your catalogue. Can this be done with a L200CA and if so could you supply a circuit diagram?

can this be used for a 12v car to reduce to 6v on a wiper motor?
Asked by: josh
No sorry this product does not support that.

Hello there do you have a ready made pcb for the L200, to build a charger for a lead acid battery. Thanks
Asked by: Andy
No sorry, we do not have these.
