Changes in output voltage due to heating effects are taken into account separately by thermal rejection. When an output capacitor is datqsheet to a regulator and the input is shorted, the output capacitor will discharge into the output of the regulator.

National Semiconductor

The dropout voltage of the IC regulator is about 1. However, other values such as or ohms can also be used for R 1. Ceramic capacitors are also good at high frequencies, but some types have a large decrease in capacitance at frequencies around 0.

Figure 3 shows an LM with protection diodes included for use with outputs greater than 25V and high values of output capacitance. Current mirror wikipedialookup. An optional output capacitor can be added to improve transient response. This publication supersedes and replaces all information previously supplied. Alternating current wikipedialookup. Surge protector wikipedialookup.

Variable-frequency drive wikipedialookup. With the TO-3 package, it is easy to minimize the resistance from the case to the set resistor, by using 2 separate leads to the case.

Tube sound wikipedialookup. They are exceptionally easy lm338o use and require only 2 resistors to set the output voltage. Distribution management system wikipedialookup. Three-phase electric power wikipedialookup.

LMK Hoja de datos ( Datasheet PDF ) – 5A Positive Adjustable Voltage Regulator

Since the regulator is “floating” and sees only the input-to-output differential voltage, supplies of several hundred volts can be regulated as long as the maximum input to input differential is not exceeded. Created 28 July Capacitor wikipedialookup. To determine the output voltage, enter values for the program R 1 and set Dqtasheet 2 datasueet and hit the “Calculate” button. Where greater output current is required, the LM series regulators are suitable up to 3A and the LM series voltage regulators for up to 5A of output.

Please update your bookmarks. Regulator with Line Resistance in Output Lead. Thank you for your participation!

The discharge current depends on the value of the capacitor, the output voltage of the regulator, and the rate of decrease of VI. Two-port network wikipedialookup.

However, SGS-THOMSON Microelectronics assumes no responsability for the consequences of use of such information nor for any infringement of patents or other rights of third parties which may results from its use. A unique feature of the LM family is time-dependent current limiting. Regulator with Protection Diodes. Last update 6 January Regulation is measured at constant junction temperature.

This bypass capacitor prevents ripple form being amplified as the output voltage is increased. Buck converter wikipedialookup. The device is more sensitive to the absence of input bypassing when adjustment or output capacitors are used byt the above values will eliminate the possibility of problems.

Even small capacitors can have a low enough internal series resistance to be able to deliver 20A spikes when shorted.

Resistive opto-isolator wikipedialookup. An optional output capacitor can be added to improve transient response. You don’t want to use too high an input voltage as the excess will need to be dissipated as heat through the regulator.

Rectifier wikipedialookup. This occurs with values between pF and pF.

Under sustained loading conditions, the current limit decreases to a safe value protecting the regulator. Transistor wikipedialookup.
