LM1117MP-3.3/NOPB  

Linear & Switching Voltage Regulators

The LM1117MP-3.3/NOPB is a linear voltage regulator manufactured by Texas Instruments. It is designed to provide a stable and consistent output voltage of 3.3 volts from an input voltage source that may vary. Here is a description of the model, its features, and potential applications:

Description:

The LM1117MP-3.3/NOPB is a member of the LM1117 family of adjustable voltage regulators. It is a positive voltage regulator with an output voltage of 3.3V. The "MP" in the model number indicates that it is a miniature package version, which is compact and suitable for space-constrained applications. The "NOPB" indicates that the device is no longer in production but is still available through various distributors.

Features:

1. Output Voltage: The regulator provides a fixed output voltage of 3.3V.
2. Input Voltage Range: It can accept a wide range of input voltages, typically from 4V to 40V, making it versatile for different power sources.
3. Output Current: The LM1117MP-3.3/NOPB is capable of supplying a continuous output current up to 800mA.
4. Low Dropout Voltage: It has a low dropout voltage, which means it can regulate the output voltage accurately even when the input voltage is close to the output voltage.
5. Thermal Protection: The device includes thermal shutdown protection to prevent damage in the event of overheating.
6. Miniature Package: It comes in a small SOT223 package, which is suitable for compact designs.

Applications:

1. Portable Electronics: Due to its small size and low power consumption, it's ideal for use in portable electronic devices that require a stable 3.3V power supply.
2. Microcontroller Power: It can be used to power microcontrollers and other integrated circuits that operate at 3.3V.
3. Sensors and Transducers: The LM1117MP-3.3/NOPB can provide a stable power supply to sensors and transducers that require a consistent voltage for accurate operation.
4. Battery-Powered Devices: It can be used in battery-powered devices to regulate the voltage from batteries, which may vary over time or with different battery chemistries.
5. Test and Measurement Equipment: The regulator can be used in test and measurement equipment where a stable reference voltage is required.

It's important to note that while the LM1117MP-3.3/NOPB is a reliable and widely used regulator, it may not be the best choice for high-current applications or for situations where a more modern regulator with higher efficiency or additional features is needed. Always consider the specific requirements of your application when selecting a voltage regulator.
