LMT-5 Datasheet

By grounding the feedback pin, the regulator senses the inverted output voltage and regulates it. Elcodis is a trademark of Elcodis Company Ltd.

Feedback LM mH Output Output Voltage Ripple and Transients Source of the Datashee 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.

In many cases, the power dissipated by the LM regulator is so. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. Copy your embed code and put on your site: The reverse voltage rating of the diode should be at least 1.

All other trademarks are the property of their respective owners. These devices are available lmm2575t-5 fixed output voltages of 3.

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. Download datasheet Kb Share this page. Stresses exceeding Maximum Ratings may damage the device. All circuits of this series are. For a robust design the diode should have a current rating equal to the maximum current limit of the LM to be able dataheet withstand a continuous output short B.

This picture does not show the complete circuit.

Inductor The magnetic components are the cornerstone of all switching power supply designs Functional operation above the Recommended Operating Conditions dwtasheet not implied. Table 4 provides a list of suitable diodes for the LM regulator. In the Adjustable version of the LM lm22575t-5 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.

Output Capacitor Selection C out A.

Adjustable Version Output Voltage Range of 1. The LM series of regulators are monolithic integrated circuits. See general marking information in the device marking. Maximum Ratings are stress ratings only. For stable operation, the capacitor must satisfy the When the LM is used as shown in the Figure 14 test circuit, system performance will be as shown in system parameters section.
