The LT3050EDDB-5#TRPBF is a high-performance, low dropout linear regulator (LDO) from Linear Technology, designed to deliver a continuous output current of up to 100mA with a dropout voltage of only 340mV at full load. This makes it an ideal choice for battery-powered systems and other applications where power efficiency is crucial.

Key Features:

• Output Voltage: The device provides a fixed output voltage of 5V, which is suitable for a wide range of digital and analog circuits.
• Low Noise: With only 30µVRMS of output noise over a 10Hz to 100kHz bandwidth, the LT3050 is perfect for noise-sensitive applications such as audio, RF, and precision instrumentation.
• High PSRR: It offers an excellent power supply rejection ratio (PSRR) of 76dB at 1kHz, ensuring stable output voltage despite variations in input voltage.
• Adjustable Current Limit: The current limit can be set with a single resistor, providing flexibility and protection for the regulator and the load.
• Thermal Protection: The device includes internal thermal shutdown protection to prevent damage from overheating.

Applications:

The LT3050EDDB-5#TRPBF is versatile and can be used in a variety of applications, including:

• Portable and battery-powered equipment
