2x National Semiconductor IC LM337AT Lm337

To optimize the heat. F capacitors are optional to improve ripple rejection. Failure to do this may cause the circuit to short. In Figure 2when the 10W pulse is applied for ms. Substances” as defined in CSPS2. V OUTper Watt, within the first 10 ms after a step of power is.

Although power dissipation is internally limited, these specifications. C, 10 ms Pulse.


LM 3-Terminal Adjustable Negative Regulators « Datasheet Component Blog

The LM negative complement to the LM regulates voltages below, rather than above, the reference. Accidenti come scotta questo transistor. Note that the load regulation error. The LM is an adjustable analogue to the popular 78xx fixed regulators. Archived from the original PDF on 18 April Linear integrated circuits Voltage regulation.

The LM’s specification is 0. Maximum Power Dissipation vs.

A critical component is any component of a life support. The LM relates in the same way to the fixed 79xx regulators. 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.

Further, the LM series features internal current limiting. 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 lj337 this case is labelled ” ground “. Higher regulated voltages are obtained by connecting the adjustment pin to a resistive voltage divider between the output and ground.


Unless otherwise specified, these specifications apply ? The thermal regulation of a.

Load regulation typically 0. In use an LM commonly requires a heat sink to prevent the operating temperature rising too high. When power is dissipated in an IC, a temperature gradient.

However, the 78xx device’s quiescent current is substantially higher and less natiojal. F of aluminum or tantalum. Thermal regulation depends on IC layout. C for the LM, 0? Line regulation typically 0. K Steel and T Packages. Europe Customer Support Center.
