Linear regulators inherently waste power, the power dissipated is the current passed multiplied by the voltage difference between input and output. The LM is an adjustable analogue to the popular 78xx fixed regulators.
Retrieved 31 March Page 27 Notes 27 www. Of Outputs 1 No. For applications requiring greater output current, see LM All other trademarks are the property of their respective owners.
Page 12 Layout Top Side Note: Full output current not available at high input-output voltages. Because some quiescent current flows from the adjustment pin of the device, an error term is added:.
Besides replacing fixed regulators, the LM is useful in a. In addition to higher performance than fixed regulators, the.

Archived from the original PDF on 18 April An optional output ca. 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 “. Because of this, the error term in the formula cannot be ignored and the value of the low-side resistor becomes more critical.
For large voltage differences, the energy lost as heat can ultimately be greater than that provided to the circuit.
The alternative is to use a switching voltage regulator which is usually more efficient but has a larger footprint and requires a larger number of associated components.
