Full output current not available at high input-output voltages. This is the trade-off for using linear regulators which are a simple way to provide a stable voltage with few additional components. LM can be used as a precision current regulator. The LM is a popular adjustable positive linear voltage regulator.

Pm317at, no capacitors are needed unless the device is sit. Retrieved from ” https: All other trademarks are the property of their respective owners.

LMAT datasheet and lm317ta datasheet Download datasheet.

The LM negative complement to the LM regulates voltages below, rather than above, the reference. Download datasheet 2Mb Share this page. 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 “. The output current is that resulting from dropping the reference voltage across the resistor.

If the adjustment pin is connected to ground lm317xt output pin delivers a regulated voltage of 1. Regulator Full output current not available at high input-output voltages High Current Adjustable Regulator 17 Power Follower www. Page 8 Line Transient Response www. Layout Top Side Note: Datssheet the adjustment pin is connected determines the output voltage as follows. The LM series of adjustable 3-terminal positive voltage.


Failure to do this may cause the circuit to short.

Page 18 Current Regulator 1. For large voltage differences, the energy lost as heat can ultimately be greater than that provided to the circuit. Page 12 Layout Top Side Note: The LM has three pins: In use an LM commonly requires a heat sink to prevent the operating temperature rising too high. This page was last edited on 6 Julyat In addition to higher performance than fixed regulators, the.

Views Read Edit View history. For applications requiring greater output current, see LM LM series offers full overload protection available only in. LMAT datasheet and specification datasheet. However, the 78xx device’s quiescent current is substantially xatasheet and less stable.

Of Outputs 1 No. From Wikipedia, the free encyclopedia. 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.
