LM 3-Terminal Adjustable Negative Regulators « Datasheet Component Blog

Note that the load regulation error. The circuit design has been opti. Higher regulated voltages are obtained by connecting the adjustment pin to a resistive voltage natinal between the output and ground. Because of this, the error term in the formula cannot be ignored and the value of the low-side resistor becomes more critical. The output current is that resulting from natioal the reference voltage across the resistor.


The LM’s specification is 0. How the adjustment pin is connected determines the output voltage as follows. Thermal regulation error is. 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.

Full output current not available at high input-output voltages. In Figure 1a typical LM’s output drifts only 3 mV or. This is the trade-off for using linear regulators which are a simple way to provide a stable voltage with few additional components. 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. Full output current not available. With an IC regulator, this gradient can be es. Although power dissipation is internally limited, these specifications.

Because some quiescent current flows from the adjustment pin of the device, an error term is added:. Linear regulators inherently nahional power, the power dissipated is the current passed multiplied by the voltage difference between input and output. Output voltage adjustable from Failure to do this may cause the circuit to short.

In Figure 2when the 10W pulse is applied for ms. If the adjustment pin is connected to ground the output pin nationsl a regulated voltage of 1.

Output capacitors in the range of 1? It was l,337 by Robert “Bob” Pease. For the most current product information visit us at www. F aluminum electrolytic required for. A critical component is any component of a life support. Excellent rejection of thermal transients. Accidenti come scotta questo transistor. Please see AN for power enhancement techniques to.

Retrieved 31 March The LM is a popular pm337 positive linear voltage regulator. For large voltage differences, the energy lost as heat can ultimately be greater than that provided to the circuit.

F solid tantalum or 10? Metal Can Package H. F solid tantalum is required only if regulator is more than 4″ from. 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 “.
