The LT3027IDD#TR is a high-performance, dual low dropout regulator (LDO) offered by Linear Technology, now part of Analog Devices. Designed to cater to applications requiring low noise, high power supply rejection ratio (PSRR), and ease of use, this LDO is a robust solution for powering sensitive analog circuits.

Key Features

• Output Voltage Range: The LT3027 provides a wide output voltage range, delivering versatility for various applications. Each of the two LDOs can output from 1.22V to 20V, which can be set by external resistors.
• Low Dropout Voltage: With a low dropout voltage of typically 300mV at full load, the LT3027 ensures efficient operation, even when the input-to-output voltage differential is small.
• High Output Current: The device can deliver up to 100mA on each channel, making it suitable for a range of moderate power applications.
• Low Noise: The LT3027 features a low noise output, which is critical for sensitive RF and precision analog circuits. The noise can be further reduced with an optional bypass capacitor.
• High PSRR: With a high PSRR of up to 75dB at 1kHz, the regulator significantly suppresses input supply ripple, benefiting applications that demand clean voltage sources.
• Thermal Protection: The device includes internal thermal shutdown protection to safeguard against overheating and potential damage.

Applications

The LT3027IDD#TR is ideal for a variety of applications, including but not limited to:

• Portable and battery-powered equipment
• Microprocessor supply
• Power supplies for sensitive RF and analog circuits
• Automotive electronics
• Industrial controls

Package and Availability

The LT3027 is available in a compact 10-lead DFN package (LT3027IDD#TR), which is suitable for space-constrained applications. The part is also available in tape and reel form, facilitating efficient assembly for mass production. With its combination of features, the LT3027 is an excellent choice for designers looking for a reliable and high-quality dual LDO solution.
