1.5 - 35 Volt DC Regulated Power Supply

The easy way to power your projects

Here is the circuit diagram of regulated power supply. It is a small power supply that provides a regulated voltage, adjustable between 1.5 and 35 volts at 1 ampere. This circuit is ready to use, you just need to add a suitable transformer. This circuit is thermal overload protected because the current limiter and thermal overload protection are included in the IC.

Specifications :

  • Preset any voltage between 1.5 and 35V
  • Very low ripple (80dB rejection)
  • Short-circuit, thermal and overload protection
  • Max input voltage : 28VAC or 40VDC
  • Max dissipation : 15W (with heatsink)
  • Dimensions : 52×52mm (2.1” x 2.1”)

Technical Specifications

  • Input Voltage = 40Vdc max Transformer
  • Output Voltage = 1.5V to 35Vdc
  • Output Current = 1.5 Amps max.
  • Power Dissipation = 15W max (cooled)

Note:
It has not to be cooled if used for small powers. 28 Volt AC max is allowed for the input voltage.
