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. Normally, no capacitors are needed unless the device is sit. Higher regulated voltages are obtained by connecting the adjustment pin to datashfet resistive voltage divider between the output and ground.

Output capacitors in the range. The LM is an adjustable analogue to the popular 78xx fixed regulators. Prev Next 3-Terminal Adjustable Regulator.

This is the trade-off for using linear regulators which are a simple way to provide a stable voltage with few additional components. The LM is designed to compensate for these fluctuations internally, making such measures unnecessary.

It was designed by Robert “Bob” Pease. Page 18 Current Lm1177h 1. LMH datasheet and specification datasheet. Page 27 Notes 27 www. The LM relates in the same way to the fixed 79xx regulators.

LM can be used as a precision current regulator. In packages with a heat-dissipating mounting tab, such as TOthe tab is connected internally to the output pin which may make it necessary to electrically isolate the tab or the heat sink from other parts of the application circuit.

In use an LM lm117u requires a heat sink to prevent the operating temperature rising too high. Retrieved 31 March However, the 78xx device’s quiescent current is substantially higher and less stable. Included on the chip are current limit, thermal overload.

Further, both line and load regulation are better than.

In addition to higher performance than fixed regulators, the. Because of this, the error term in the formula cannot be ignored and the value of the low-side resistor becomes more critical.
