Maximum Ratings are stress ratings only. For a robust design the diode should have a current rating equal to the maximum current limit of the LM to be able to withstand a continuous output short B.

This picture does not show the complete circuit. The reverse voltage rating of the diode should be at least 1. Undervoltage Lockout Circuit for http: For a robust design, the diode should have a current rating equal to the maximum current limit of the LM to be able to withstand a continuous output short.

The output ripple voltage value ranges from 0. Table 4 provides a list of suitable diodes for the LM regulator. Copy your embed code and put on your site: All circuits of this series are. These devices are available in fixed output voltages of 3.


In many cases, the power dissipated by datasheeet LM regulator is so. Output Voltage Ripple and Transients Source of the Output Ripple Since the LM is a switch mode power supply regulator, its output voltage, if left unfiltered, will contain a sawtooth ripple voltage at the switching frequency.

To simplify the inductor selection process, an inductor selection guide for the LM regulator was added to this data sheet Figures 17 through External components such as the catch diode, inductor, input and output capacitors can affect switching regulator system performance.

In the Adjustable version of the LM switching regulator this pin is the direct input of the error amplifier and the resistor network R2 connected externally to allow programming of the output voltage.

Unless otherwise specified for the Datashwet detailed ordering and shipping information in the package. The LM series of regulators are monolithic integrated circuits. Feedback LM mH Output Functional operation above the Recommended Operating Conditions is not implied.

Adjustable Version Output Voltage Range of 1. Table 1 and Table 2 of this Indicator Selection Guide shows some examples of different manufacturer products suitable for design with the LM See general marking information in the device marking.

For stable 2575t- the capacitor must satisfy the Inductor The magnetic components are the cornerstone datashete all switching power supply designs Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.

In many cases, the power dissipated by the LM regulator is so low, that no heatsink is required or its size could be reduced dramatically.

By grounding the feedback pin, the regulator senses the inverted output voltage and regulates it. When the LM is used as shown in the Figure 14 test circuit, system performance will be as shown in system datashee section.
