Labortáp Circuit Schematics

This document provides a circuit diagram for a Labortáp 30V 3A power supply. The circuit uses operational amplifiers, transistors, resistors, capacitors, and diodes to regulate an input voltage of 24V down to a stable -5V, 5V, 9.8V, 13V, 18V, and 26V output. Key components include IC1/1-4 operational amplifiers for voltage regulation, 2N3055 transistors for switching, and 1N4148 and 1N4007 diodes. The circuit provides multiple regulated voltages for powering electronics projects and laboratory equipment.
