Product Overview

The MIC5255-3.3BM5-TR is a high-performance, low dropout regulator (LDO) from Microchip Technology, designed to provide a stable and reliable power supply for a wide range of applications. This LDO is capable of delivering up to 150mA of continuous output current and has a fixed output voltage of 3.3V, making it an ideal choice for powering low-power devices and microcontrollers.

Key Features

• Low Dropout Voltage: The MIC5255 offers an extremely low dropout voltage, which means it can maintain a constant output voltage even when the input voltage is very close to the output voltage. This is particularly useful in battery-powered applications where maximizing battery life is crucial.
• High Output Accuracy: With an output voltage accuracy of ±2%, this LDO ensures precise voltage regulation, critical for sensitive electronic circuits.
• Low Quiescent Current: The MIC5255-3.3BM5-TR boasts a low quiescent current of typically 50µA, which minimizes power consumption when the device is in standby mode, thereby extending battery life in portable applications.
• Thermal Shutdown and Current Limit: Built-in safety features such as thermal shutdown and current limit protect the device and the load from damage due to overheating and overcurrent conditions.
• Fast Transient Response: This LDO is designed to respond quickly to changes in load, which helps maintain a stable output voltage during rapid load changes.

Applications

The MIC5255-3.3BM5-TR is versatile and can be used in a variety of applications, including but not limited to:

• Mobile phones and PDAs
• Digital cameras and audio devices
• Portable and battery-powered equipment
• Wireless LAN devices
• Microcontroller power supplies

Packaging and Availability

The MIC5255-3.3BM5-TR is available in a small, 5-pin SOT-23 package, which is suitable for space-constrained applications. The "TR" suffix indicates that the product is offered in tape and reel packaging, making it ideal for automated assembly processes. As part of Microchip Technology's commitment to quality, this LDO is designed to meet high standards of performance and reliability.
