Vue d'ensemble
Description
Key features include a wide input voltage range, typically from 4.5V to 20V, and built-in protection mechanisms such as overcurrent, thermal shutdown, and short-circuit protection, ensuring reliability and safety in various applications. The LD2981ABM50TR is commonly used in consumer electronics, telecommunications, and automotive power supplies where efficient voltage regulation is critical.
Packaged in a small form factor, it allows for efficient thermal dissipation and easy integration into compact designs. Overall, the LD2981ABM50TR is suitable for applications requiring reliable and efficient voltage regulation.
Features
- Output Voltage: Fixed output of 5V with a tolerance of ±1%.
- Dropout Voltage: Low dropout voltage (typically 300mV at 1A), allowing for efficient operation even with minimal input-output voltage differences.
- Output Current: Capable of sourcing up to 1.5A of output current.
- Thermal Protection: Integrated thermal shutdown to prevent damage under overheating conditions.
- Current Limiting: Short-circuit protection through current limiting to enhance reliability.
- Stability: Requires only a small output capacitor for stability, simplifying circuit design.
- Operating Temperature: Suitable for a wide temperature range, typically from -40°C to +125°C.
- Package: Available in a compact SO-8 package for space-efficient designs.
This LDO is ideal for powering microcontrollers, sensors, and other low-voltage devices in consumer electronics, automotive, and industrial applications.
Package
Pinout
The functions of the pins are as follows:
1. Input (VIN) - This pin is for the input voltage that the regulator will convert.
2. Output (VOUT) - This pin provides the regulated output voltage.
3. Ground (GND) - This pin connects to the ground reference of the circuit.
4. Enable (EN) - This pin is used to enable or disable the output; a high voltage turns the regulator on.
5. Feedback (FB) - This pin is used for voltage feedback to maintain the desired output voltage.
The LD2981ABM50TR typically provides a fixed output of 5V and is designed for applications requiring low dropout voltage and high output current capabilities.
