Die 5V-3.3VReg-Platine ist eine Zusatzplatine mit integriertem Regler. Dieser Regler dient zur lokalen Regelung auf der Karte, indem er die Spannung von 8-16 V AC/DC auf 5 V oder 3,3 V DC reduziert.
Die 5V-3,3V-Reg-Platine ist sehr praktisch für Systeme, die eine geregelte 3,3V- oder 5V-Stromversorgung benötigen.
Provide a stable and reliable 3.3V and 5V power supply to the device using the 5V-3.3V Reg Board. This regulator board features a LM7805 3-terminal 5V positive voltage regulator and a MC33269 3.3V low dropout positive voltage regulator to provide fixed supply voltages. The board features two voltage input options, which includes a screw terminal connector CN2 and AC/DC adapter connector CN1 (8 to 16V AC/DC). An on-board voltage regulator is used to reduce and stabilize the supplied voltage. The reduced voltage may be either 3.3V or 5V and is delivered via screw terminals CN3 (5V) and CN4 (3.3V). For 5V voltage, the maximum current amounts to 1A, whereas for 3.3V voltage, it amounts to 800 mA. Furthermore, 5V-3.3V Reg Board is provided with mounting holes for easy integration into the design. The board has a diode bridge of four 1N4007 diodes that performs as a rectifier when using an AC input, and as polarity protection when using a DC input.
IC/Module: LM7805 Positive Voltage Regulator
The LM7805 is a three-terminal positive voltage regulator with several fixed output voltages. Highly useful in a wide range of applications, this voltage regulator employs internal current limiting, thermal shutdown, and safe operating area protection. If adequate heat sinking is provided, it can deliver output current up to 1A.
IC/Module: MC33269 800 mA, Adjustable Output, Low Dropout Voltage Regulator
The MC33269 is a low dropout positive voltage regulator that works well for a wide range of low input voltage applications. It works as a cheap and reliable solution for precision voltage regulation while keeping the power losses to a minimum. It comprises of a 1V dropout composite PNP-NPN pass transistor, current limiting, and thermal shutdown.
