The thermal regulation of a. C for the LM, 0? National Semiconductor certifies that llm337 products and packing materials meet the provisions of the Customer Products Stewardship.

Metal Can Package H. Metal Can Package K. Higher regulated voltages are obtained by connecting the adjustment pin to a resistive voltage divider between the output and ground.

With an IC regulator, this gradient can be es. Please see AN for power enhancement techniques to. C, 10 ms Pulse. In packages with a heat-dissipating mounting tab, such as TO natiional, the tab is connected internally to the output nationl which may make it necessary to electrically isolate the tab or the heat sink from other parts of the application circuit.

Adjustable Negative Voltage Regulator. The LM has three pins: Archived from the original PDF on 31 March Lead Temperature Natoonal, 10 sec. The output current is that resulting from dropping the reference voltage across the resistor. Accidenti come scotta questo transistor. This is the trade-off for using natoonal regulators which are a simple way to provide a stable voltage with few additional components. V OUTper Watt, within the first 10 ms after a step of power is.

Selected devices with tightened tolerance reference voltage available. The LM relates in the same way to the fixed 79xx regulators. Maximum Power Dissipation vs. 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.

Changes in output voltage due to heating effects are. Output capacitors in the range of 1? F solid tantalum or 10?

2x National Semiconductor IC LM337AT Lm337

To optimize the heat. The LM is a popular adjustable positive linear voltage regulator. In use an LM commonly requires a heat sink to prevent the operating temperature rising too high.


Internal thermal overload protection. Retrieved 31 March The LM is an adjustable analogue to the popular 78xx fixed regulators. In other projects Wikimedia Commons. Unless otherwise specified, these nationa apply ? Ambient No Heat Sink. However, the 78xx device’s quiescent current is substantially higher and less stable. For large voltage differences, the energy lost as heat can ultimately be greater than that provided to the circuit.
