The mechanism used is similar enough that a voltage divider can be used in the same way as with the LM and the output follows the same formula, using the regulator’s fixed voltage for V ref e.

Archived from the original ln117h 17 December Also, it makes an especially simple adjustable switching reg. LM can be used as a precision current regulator.

Also, the LM is packaged in.

LM117H – LM117 3-Terminal Adjustable Voltage Regulator Datasheet

This is the trade-off for using linear regulators which are a simple way to provide a stable voltage with few additional om117h. Page 12 Layout Top Side Note: Output capacitors in the range. The LM is a popular adjustable positive linear voltage regulator. An optional output ca.

For applications requiring greater output current, see LM Of Outputs 1 No. LMH datasheet and specification datasheet.

However, the 78xx device’s quiescent current is substantially higher lm117 less stable. In other projects Wikimedia Commons.

The output current is that resulting from dropping the reference voltage across the resistor. For large voltage differences, the energy lost as heat can ultimately be greater than that provided to the circuit.
