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. Stresses exceeding Maximum Ratings may damage the device.

Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.

Feedback LM mH Output External components such as the catch diode, inductor, input and output capacitors can affect switching regulator system performance. When the LM is used as shown in the Figure 14 test circuit, system performance will be as shown in system parameters section.

Unless otherwise specified for the In the Adjustable version of the Daatsheet 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. 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. The reverse voltage rating of the diode should be at least 1.


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. Output Capacitor Selection C out A. For stable operation, the capacitor must satisfy the Table 1 and Table 2 fatasheet this Indicator Selection Guide shows some examples of different manufacturer products suitable for design with the LM Device listed in bold are available from ON Semiconductor.

Table 4 provides a ddatasheet of suitable diodes for the LM regulator.

Inductor The magnetic components are the cornerstone of all switching power supply designs To simplify the inductor selection process, an inductor selection guide for the LM regulator was datashewt to this data sheet Figures 17 through 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.


The output ripple voltage value ranges from 0. By grounding the feedback pin, the regulator senses the inverted output voltage and regulates it.
