5V-16V Linear Power Supply Kit User's Guide
Overview
This kit is designed to fill the need for a power supply which can be connected to the mains
electrical supply of your house and which can provide the range of DC voltages that are
required for basic electronic projects. The circuit is basic but it will satisfy the requirements
of most electronic kit users especially when starting out. Two DC voltage outputs are
available. One is a fixed regulated 5V for TTL use. The other output is variable from 5V
upwards. The maximum output voltage depends on the input voltage. The specified
maximum input DC voltage to the regulator is 16V. The minimum input voltage must be 2V
higher than the regulated output voltage.
