Retrieved catasheet ” https: The LM is a popular adjustable positive linear voltage regulator. The LM negative complement to the LM regulates voltages below, rather than above, the reference. Full output current not available at high input-output voltages. The device can be configured to regulate the current to a load, rather than the voltage, by replacing the low-side resistor of the divider with the load itself.

Maximum Allowable Power Dissipation vs. Page 27 Notes 27 www. Archived from the original PDF on 31 March However, the 78xx device’s quiescent current is substantially higher and less stable.

In addition to higher performance than fixed regulators, the. For large voltage differences, the energy lost as heat can ultimately be greater than that provided to the circuit.

In other projects Wikimedia Commons. Like the LM, each datasheft 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 “. REF The reference voltage is impressed across program resistor R1 and, since the voltage is constant, a constant current I By using this site, you agree to the Terms of Use and Privacy Policy.
