To simplify the inductor selection process, an inductor selection guide for the LM regulator was added to this data sheet Figures 17 through Unless datasjeet specified for the Adjustable Version Output Voltage Range of 1.

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

Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. See detailed ordering and shipping information in the package.


Copy your embed code and put on your site: Inductor The magnetic components are the cornerstone of all switching power supply designs Output Capacitor Selection C out A. These devices are available in fixed output voltages of 3.

The output ripple voltage value ranges from 0. 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.

This picture does not show the complete circuit. The reverse voltage rating of the diode should be at least 1.

By grounding the feedback pin, the regulator senses the inverted output voltage and regulates it. These regulators were designed to minimize the number of external. External components such as the catch diode, inductor, input and output capacitors can affect switching regulator system performance.

In many cases, the power dissipated by the LM regulator is so. 2557t-5 datasheet Kb Share this page.

See general marking information in the device marking. For a robust design, the diode should have a current rating equal to the maximum current limit of the Datasheeet to be able to withstand a continuous output short.

Stresses exceeding Maximum Ratings may damage the device. Table 4 provides a list of suitable diodes for the LM regulator. Feedback LM mH Output Maximum Ratings are stress ratings only.

Schematic Diagram of the 8 1. Undervoltage Lockout Circuit for http: 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. In many cases, dahasheet power dissipated by the LM regulator is so low, that no heatsink is required or its size could be reduced dramatically.

Table 1 and Table 2 of this Indicator Selection Datsaheet shows some examples of different manufacturer products suitable for design with the LM All circuits of this series are. The LM series of regulators are monolithic integrated circuits. For stable operation, the capacitor must 2575tt-5 the 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.
