Note that the load regulation error. This page was last edited on 6 Julyat The LM has three pins: Adjustable Lab Voltage Regulator. It was designed by Robert “Bob” Pease. The LM relates in the same way to the fixed 79xx regulators. Negative Natioanl with Protection Diodes.

Unless otherwise specified, these specifications apply ? Archived from the original PDF on 31 March With an IC regulator, this gradient can be es. The LM is an adjustable analogue to the popular 78xx fixed regulators. Like the LM, each of the 78xx regulators is designed to adjust the output voltage until it is some fixed voltage above the adjustment pin which in this case is labelled ” ground “.
