    Applications

    1. Consumer Electronics

    Smart Home Devices: Such as Wi-Fi smart plugs, sensors, remotes, etc., used to power the main MCU and sensor modules.

    Portable Devices: Such as MP3 players, digital photo frames, handheld fans, etc., for voltage conversion and regulation for downstream circuits.

    Computer Peripherals: Such as auxiliary power on motherboards, USB hubs, internal cards.

    2. Communication & Networking Equipment

    Network Modules: Providing power for earlier-generation Ethernet controllers and Wi-Fi modules (which often require a 3.3V supply).

    Routers/Switches: Providing auxiliary power for certain chips on the board.

    Optical Modules: Also used in some traditional optical transceivers.

    3. Industrial Control & Automation

    Industrial Control Boards: Providing 3.3V power for logic circuits, MCUs, op-amps, etc., in PLCs and industrial controllers.

    Sensor Interfaces: Many sensors (temperature, pressure, humidity) operate at 3.3V, making the LD1117 an ideal power source.

    Measurement & Test Equipment: Powering analog and digital circuits in data acquisition cards and instruments.

    4. Automotive ElectronicsIn-Vehicle Infotainment Systems: Powering low-power components in devices like radios, navigation systems.

    Body Control Modules: Such as window controllers, wiper controllers, and other ECU units requiring a stable 3.3V supply.

    5. Embedded Systems & Projects

    Arduino Shields: Commonly used on shields to convert a higher voltage (e.g., 5V or 9V) down to 3.3V for powering 3.3V sensors or devices.

    Raspberry Pi/STM32 Development Boards: Used in custom expansion boards or projects to provide a 3.3V power rail for external components.

    Electronic DIY Projects: Used in almost any hobbyist or professional project that requires stepping down from inputs like 5V/6V/9V to 3.3V.


    Description

    The LD1117 is a low drop voltage regulator able to provide up to 800 mA of output current, available even in adjustable version (VREF = 1.25 V). Concerning fixed versions, are offered the following output voltages: 1.2 V, 1.8 V, 2.5 V, 3.3 V and 5.0 V. The device is supplied in: SOT-223, DPAK, SO-8 and TO-220. The SOT 223 and DPAK surface mount packages optimize the thermal characteristics even offering a relevant space saving effect. High efficiency is assured by NPN pass transistor. In fact in this case, unlike than PNP one, the quiescent current flows mostly into the load. Only a very common 10 µF minimum capacitor is needed for stability.

    On chip trimming allows the regulator to reach a very tight output voltage tolerance, within ± 1 % at 25 °C. The adjustable LD1117 is pin to pin compatible with the other standard. Adjustable voltage regulators maintaining the better performances in terms of drop and tolerance.
