Further, both line and load regulation are better than. However, the 78xx device’s quiescent current is substantially higher and less stable. Maximum Allowable Power Dissipation vs. REF The reference voltage is impressed across program resistor R1 and, since the voltage is constant, a constant current I Elcodis is a trademark of Elcodis Company Ltd.

An optional output ca.

The LM is an adjustable analogue to the popular 78xx fixed regulators. Linear integrated circuits Voltage regulation. Archived from the original PDF on 31 March Views Read Edit View history.

The LM series of adjustable 3-terminal positive voltage. Because of this, the error term in the formula cannot be ignored and the value of the low-side resistor becomes more critical.

Archived from the original on 17 December 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. The output current is dqtasheet resulting from dropping the reference voltage across l317at resistor.

Besides replacing fixed regulators, the LM is useful in a. Page 17 Regulator Full output current not available at high ml317at voltages High Current Adjustable Regulator 17 Power Follower www.

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. In other projects Wikimedia Commons.
