The SGM2007-2.8XN5/TR is a low-dropout (LDO) linear regulator from SG Micro Corp that provides a stable 2.8V output. It's designed for portable and battery-powered applications that require an efficient and compact voltage regulator. The XN5 package denotes a small footprint, and the “/TR” suffix indicates that the component is supplied on tape and reel for automated assembly. This regulator is known for its low quiescent current, which contributes to extended battery life.

Applications:

• Smart Cards: Providing a stable 2.8V power supply for smart card ICs.
• Remote Controls: Powering IR transmitters and microcontrollers.
• Wireless Audio Devices: Regulating voltage for audio codecs and amplifiers.
• Portable Data Loggers: Supplying a stable voltage to memory and sensor components.
• Low-Power Communication Modules: Providing a clean 2.8V power source.
• Medical Monitoring Devices: Power management for portable health devices.

Features:

• Fixed 2.8V Output: Provides a precise and stable 2.8V output voltage.
• Low Dropout Voltage: Ensures efficient operation even with a small difference between input and output voltage.
• Low Quiescent Current: Minimizes power consumption when the regulator is not actively supplying current.
• Over-Current Protection: Protects the regulator and the connected load from excessive current draw.
• Short-Circuit Protection: Prevents damage in case of a short circuit at the output.
• Thermal Shutdown Protection: Shuts down the regulator when the junction temperature exceeds a safe limit.
• XN5 Package: Small footprint allows for compact designs in portable applications.

Benefits:

• Extended Battery Life: The low quiescent current helps to extend battery life in portable devices.
• Stable Output Voltage: Ensures consistent performance of the powered device, even with variations in input voltage or load current.
• Enhanced System Reliability: The built-in protection features protect the regulator and the connected load from damage.
• Reduced Board Space: The small XN5 package allows for compact designs, saving valuable board space.
• Automated Assembly: Tape and reel packaging simplifies automated assembly processes.

Additional Details:

The SGM2007-2.8XN5/TR comes in the XN5 package and is provided on tape and reel for automated pick-and-place assembly. The input voltage typically ranges from 3.0V to 5.5V. The low dropout voltage allows it to function efficiently as the battery voltage declines. It is an excellent choice for applications where space, efficiency, and reliable 2.8V power are critical.
