LMH National Semiconductor, LMH Datasheet

The L1m17h series of adjustable 3-terminal positive voltage. For large voltage differences, the energy lost as heat can ultimately be greater than that provided to the circuit. The LM negative complement to the LM regulates voltages below, rather than above, the reference.

The alternative is to use a switching voltage regulator which is usually more efficient but has a larger footprint and requires a larger number datasehet associated components.

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 “.


From Wikipedia, the free encyclopedia. Page 27 Notes 27 www.

Full output current not available at high input-output voltages. Copy your embed code and put on your site: Besides replacing fixed regulators, the LM is useful in a. If the adjustment pin is connected to ground the output pin delivers a catasheet voltage of 1.

The device can be configured to regulate the current to a load, rather adtasheet the voltage, by replacing the low-side resistor of the divider with the load itself.

LM series offers full overload protection available only in. Prev Next 3-Terminal Adjustable Regulator.

Of Outputs 1 No. LM can be used as a lm11h current regulator. Layout Top Side Note: Download datasheet 2Mb Share this page. The output current is that resulting from dropping the reference voltage across the resistor. The LM is designed to compensate for these fluctuations internally, making such measures unnecessary. Wikimedia Commons has media related to LM and Voltage regulator circuits.

It was designed by Robert “Bob” Pease. LMH datasheet and specification datasheet Download datasheet. Application Hints In operation, the LM develops a nominal 1. The LM relates in the same way to the fixed 79xx regulators. For applications requiring greater datasheet current, see LM Higher regulated voltages are obtained by connecting the adjustment pin to a resistive voltage divider between the output and ground.

Included on the chip are current limit, thermal overload.
