Device listed in bold are available from ON Semiconductor. The LM series of regulators are monolithic integrated circuits. Adjustable Version Output Voltage Range of 1.

Undervoltage Lockout Circuit for http: These devices are available in fixed output voltages of 3. Copy your embed code and put on your site: 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.

In many cases, the power dissipated by the LM regulator is so. To simplify the inductor selection process, an inductor selection guide for the LM regulator was added to this data sheet Figures 17 through Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.


The reverse voltage rating of the diode should be at least 1. Download datasheet Kb Share this page. Table 1 and Table 2 of this Indicator Selection Guide shows some examples of different manufacturer products suitable for design with the LM Table 4 provides a list of suitable diodes for the LM regulator. This picture does not show the complete circuit. The output ripple voltage value ranges from 0. 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.

When the LM is used as shown in the Figure 14 test circuit, system performance will be as shown in system parameters section.

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. Elcodis is a trademark of Elcodis Company Ltd.

Schematic Diagram of the 8 1. External components such as the catch diode, inductor, input and output capacitors can affect switching regulator system performance. Unless otherwise specified for the All other trademarks are the property of their respective owners. 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.


Stresses exceeding Maximum Ratings may damage the device. Dataasheet detailed ordering and shipping information in the package.

These regulators were designed to minimize the number of external. Output Capacitor Selection C out A. See general marking information in the device marking. For stable operation, the capacitor must satisfy the Functional operation above the Recommended Operating Conditions is not implied.

By grounding the feedback pin, the regulator senses the inverted output voltage and regulates it. Feedback LM mH Output All circuits of this series are. Inductor The magnetic components are the cornerstone of all switching power supply designs 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.
