Wikimedia Commons has media related to LM and Voltage regulator circuits. In use an LM commonly requires a heat sink to prevent the operating temperature rising too high. For applications requiring greater output current, see LM For guaranteed specifications and test conditions, see the Electrical Characteristics.

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.

Because of this, the error term dataeheet the formula cannot be ignored and the value of the low-side resistor becomes more critical. Application Hints In operation, the LM develops a nominal 1. Normally, no capacitors are needed unless the device is sit.

This is the trade-off for using linear regulators which are a simple way to provide a stable voltage with few additional components.
