Introducing the LT3028EFE#PBF Dual Low Noise, Low Dropout Regulator

The LT3028EFE#PBF is a high-performance, dual low dropout voltage regulator (LDO) designed and manufactured by Linear Technology. This robust component is ideal for precision applications that require low noise, high voltage regulation, and operational reliability. It's particularly well-suited for sensitive RF and analog circuitry, such as PLLs, VCOs, high-quality audio, and instrumentation, where clean and stable power is a critical requirement.

Key Features and Benefits

• Low Noise Output: With an incredibly low noise output of just 20µVRMS across a 10Hz to 100kHz bandwidth, the LT3028EFE#PBF ensures that the power supply does not introduce significant noise into sensitive circuits.
• Dual Independent LDOs: The device features two independent LDOs, each capable of supplying 500mA of output current. This allows for versatile configurations and the powering of separate subsystems with different voltage requirements.
• Wide Input Voltage Range: The regulator operates over a wide input voltage range from 1.8V to 20V, providing flexibility in various application environments and compatibility with a variety of input sources.
• Adjustable Output Voltage: The output voltage is adjustable from 0.2V to 19.5V, which enables precise voltage regulation tailored to the specific needs of the application.
• Low Dropout Voltage: The low dropout voltage of only 300mV at full load minimizes power loss and improves efficiency, which is particularly valuable in battery-powered devices.
• Thermal Protection: The LT3028EFE#PBF includes internal thermal limit circuitry that protects the device under over-temperature conditions, ensuring long-term reliability.
• Robust Packaging: Housed in a 16-lead thermally enhanced TSSOP package, the LT3028EFE#PBF is built to handle challenging thermal environments while maintaining a compact footprint.
