Vue d'ensemble

Description

The LM1117MPX-5.0 is a low-dropout linear voltage regulator designed for applications requiring a stable 5.0V output from a higher voltage input. Part of the LM1117 series, this component offers an output current capability of up to 800mA. It is well-suited for powering microcontrollers, sensors, and other digital circuits that require 5V.
Key features of the LM1117MPX-5.0 include a dropout voltage of approximately 1.2V at full load, which allows for efficient operation even when the difference between input and output voltage is small. It also has built-in protection mechanisms such as current limiting and thermal shutdown to safeguard against overload and overheating conditions.
The device is available in a SOT-223 package, which is compact and suitable for space-constrained applications. Additionally, it offers good line and load regulation, ensuring minimal output voltage variation due to changes in input voltage or output current. The LM1117MPX-5.0 is commonly used in consumer electronics, telecommunications, and industrial applications that require a reliable 5V power supply.

Features

The LM1117MPX-5.0 is a low-dropout (LDO) voltage regulator designed to provide a stable 5.0V output from a higher input voltage. Key features include:
1. Output Voltage: Fixed at 5.0V, suitable for various 5V applications.
2. Input Voltage Range: Typically operates with an input voltage up to 15V.
3. Dropout Voltage: Low dropout voltage, typically around 1.2V at full load, allowing efficient operation with minimal input-output voltage differential.
4. Output Current Capability: Can deliver up to 800mA of output current.
5. Thermal Protection: Built-in thermal overload protection to prevent damage from overheating.
6. Short-Circuit Protection: Safeguards the device in the event of a short circuit.
7. Current Limiting: Protects the device and connected circuits by limiting the output current in overload conditions.
8. Stability: Requires external capacitors for stability, with recommendations for input and output capacitors for optimal performance.
9. Package: Available in a space-saving SOT-223 package, making it suitable for compact designs.
The LM1117MPX-5.0 is ideal for use in applications such as power supplies, battery-operated equipment, and post-regulation for switching supplies.

Package

The LM1117MPX-5.0 is typically available in a SOT-223 package. This package type is a surface-mount option that offers efficient heat dissipation and is commonly used for voltage regulators like the LM1117 series.

Pinout

The LM1117MPX-5.0 is a voltage regulator with a pin count of 3, typically available in a SOT-223 package. It is designed to provide a fixed output voltage of 5.0 volts. The three pins have the following functions:
1. Input (Vin): This pin is where the input voltage is supplied to the regulator. The input voltage should be higher than the output voltage by at least the dropout voltage to ensure proper regulation.
2. Output (Vout): This pin provides the regulated output voltage, which in this case is fixed at 5.0 volts.
3. Ground (GND): This pin is the ground reference for the regulator and is used to complete the circuit.
The LM1117 series is known for its efficiency and low dropout voltage, making it suitable for applications where space is limited and efficient power regulation is needed.
