[no high voltage today] Video by viewer request. Lm386 datasheet: www.alldatasheet.com The song is: Infected Mushroom semi nice Comment, rate and subscribe! FAQ: Q: The sound s0xx0rz, fix it! A: Can't, since there are barely any parts. Q: How do I add volume control? A: Either in series with the speaker (volume) or between pin 1 and pin 8 (gain) Q: Why is there a 7805? A: To conserve power, you can go without it if you feel like it. EDIT: Too many of the comments are goddamn retarded, so I will no longer reply. Read the other comments, your question is probably answered already.

Overview of National's SIMPLE SWITCHER® power modules with competitive bench thermal comparison. Easy-to-use SIMPLE SWITCHER power modules feature a new innovative package, and delivers best-in-class EMI and thermal performance. The modules provide high efficiency over a wide input voltage and load current range and are pin-to-pin compatible for different load currents. The LMZ-series power modules integrate a shielded inductor with synchronous DC-DC step-down topology in an easy-to-use package. The power modules provide the efficiency of a synchronous switching regulator with the simplicity of a linear regulator, eliminating the external inductor and layout placement challenges typical of switching regulator designs. LMZ Power Module Features: * Integrated shielded inductor * Supports 3.3V, 5V, 12V, 24V standard input rails * Output voltages down to 0.8V * Load currents up to 5A * Enable, external soft-start, and tracking for sequencing * Best-in-class thermal performance * Low output voltage ripple * Pin-to-pin compatible for different load currents * Easy-to-use package with single exposed copper bottom * Passes EN55022 (CISPR22) Class B Radiated EMI Standard * Passes EN61000-4-3 Industrial Standard for Radiated Immunity

with Eddie Beville, Design Manager - DC/DC uModule Regulators video.linear.com There is an alternative solution when deciding between a step-down switching regulator and a linear regulator. Switching regulators dissipate less heat than linear regulators especially when the input voltage is much higher than the output voltage or the output load current is relative high. On the other hand, linear regulators are very simple and dont require inductors. What if there was a switching regulator circuit could be simplified and fitted inside a surface mount package and the complete solution became as simple as a regulators circuit? No inductors, no MOSFETs, no difficult calculations for compensation circuitry. On paper, it is a simple square box with a few resistors and capacitors. On a PCB, it is also a simple square box with a few resistors and capacitors.

Using the LM317LZ 100ma adjustible voltage regulator and one resistor, you can make a constant current source. With the LM317 1.5 amp version, you can make one with higher currents. I made an error during the video: I said volts when I mean milliamps. (you probably figured that out though).
