This PSU is based on a common design using variable precision regulator i.c.s and can be configured to provide dual outputs in the range of +/-5V to +/-20V. The standard offerings are +/-12V and +/-15V

Some of the benefits of a 723 based design over those using a simple fixed regulator design using devices such as the 78xx/79xx are:-

• MUCH lower output noise,
• Better load regulation, and
• Better line regulation

Specification

• Output current in excess of 800mA per rail
• Current limiting at around 1.2A
• The PCB measures 133mm x 88mm
