The Acumen Labware make integrated circuit regulator is a monolithic precision voltage regulator constructed on a single silicon chip. This device consists of a temperature compensated reference, error amplifier, current limit circuit and power series pass transistor. Some of its important features are - adjustable output voltage from 2 to 37V, which could be of either polarity, 0.01% line and 0.03% load regulation, output current upto 150mA without external pass transistor make it a general purpose IC for voltage or current regulation.
The experimental set-up consists of an IC 723 which provide convenient connections, voltmeter, an ammeter, an unregulated power supply and all other general components - resistances, potentiometers, variable load etc. which are required to perform the experiments.
