About this product


  • Output current up to 1A
  • No external components required
  • Internal thermal overload protection

Product overview

• Output current up to 1A• No external components required• Internal thermal overload protection• Internal short-circuit current limiting• Output transistor safe-area compensation• Output voltage offered at 4% tolerance

This voltage regulator is monolithic integrated circuit designed as fixed voltage regulator for a wide variety of applications including local, on-card regulation. The regulator employs internal current limiting, thermal shutdown and safe area compensation. With adequate heatsink they can deliver output currents up to 1A. Although primarily designed as a fixed voltage regulator, this device can be used with external components to obtain adjustable voltages and currents.

What is the maximum input voltage for this device?

Asked by: Harry
See data sheet - input up to 35 V (40 V for the 24 V output version)

Will this device provide an output of 12 volts if the Input Voltage drops to 12 volts?

Asked by: Harry
According to the data sheet, input must be 2V above controlled output voltage

The answers to this question are confusing. Isn't this a voltage limiter, to give an output of 12 V which can only occur if the input is at least 12 V. Compare with CV model (2 A) suggests the input voltage needs to be at least 15 V, max 35 V. Help?

Thank you Dominic. It could be helpful to have a link to the data sheet in the overview of the product! I think that confirms that the answers to the previous questions are suspect.
