Introducing the LT3028EDHC Dual Low Noise, Low Dropout Regulator

The LT3028EDHC is a high-performance dual low noise, low dropout voltage linear regulator from Linear Technology, designed to provide precision voltage regulation with minimal noise. This advanced power management IC is perfect for sensitive RF and analog circuitry that requires a clean power supply for optimal performance.

The LT3028EDHC offers two independent channels, each capable of delivering up to 500mA of continuous output current. This feature allows for versatile applications in powering multiple voltage rails in a system. The regulator operates with a wide input voltage range from 1.8V to 20V, providing flexibility in various power supply configurations.

One of the key features of the LT3028EDHC is its ultra-low dropout voltage, which enables full-rated output current even when the input-to-output voltage differential is very small. This characteristic is particularly beneficial in battery-powered applications where maximizing the usage of available battery voltage is crucial.

The device also boasts exceptional low noise performance, with a low noise reference and noise reduction capability that minimizes output voltage noise, making it an ideal choice for precision analog applications such as PLLs, VCOs, high-quality audio, and sensitive instrumentation.

Additional features of the LT3028EDHC include independent shutdown controls for each channel, allowing for selective power management and reduced power consumption when a channel is not in use. The regulator also provides over-temperature and over-current protection, enhancing system reliability and longevity.

For ease of use, the LT3028EDHC is available in a 16-lead DFN package, which is compact and suitable for space-constrained applications. Its robust design ensures stable operation over a wide range of temperatures and external conditions, making it a trusted choice for designers looking to improve the performance and efficiency of their power supply designs.

In summary, the LT3028EDHC from Linear Technology is a dual-channel, low noise, low dropout regulator that offers precise voltage regulation, flexibility, and protection features that make it an excellent solution for powering sensitive electronic systems.
