The LT3009EDC-1.2#TRMPBF is a low-dropout, low-noise, adjustable micropower linear regulator, capable of supplying up to 100mA output current. It aims to offer improved noise performance, most visible when using with high-impedance loads. The device is packaged in a miniature, space-saving SOT-23 package, making it best suited for applications with limited board space. This low-noise linear regulator belongs to the category of PMIC – Voltage Regulators – Linear.

In general, the LT3009EDC-1.2#TRMPBF is an ideal power management component for a wide range of wearables and personal medical devices, where space is at a premium and the application requires the elimination of high-frequency AC noise. Typical applications include audio, digital (micro) controllers, and battery powered devices.

The LT3009EDC-1.2#TRMPBF is an adjustable regulator with an output voltage range from 0.9V to 7V. Its thermal performance has been optimized for low power and low current loads. The device requires only two external components – an external resistor for setting the output voltage, and an external capacitor for providing stable ripple rejection. The LT3009EDC-1.2#TRMPBF is designed to provide a very high power supply rejection ratio and an ultra-low output voltage ripple. The low-noise feature is enabled by the combination of low-dropout linear andlow-noise switching regulators.

The LT3009EDC-1.2#TRMPBF features a 1V drop-out voltage, which is significantly lower than traditional linear regulators. In addition, a low-resistance power switch is integrated, which keeps the power dissipation and heat generation low. The high current limit and thermal shutdown protection features ensure reliable operations over an extended temperature range.

To summarize, the LT3009EDC-1.2#TRMPBF is a low-noise linear regulator that belongs to the category of PMIC – Voltage Regulators – Linear. It is specially designed to address the power management requirements of wearable and personal medical devices. The device is provided in a miniature SOT-23 package, giving designers more flexibility when it comes to size and component count. In addition to its low-noise operation, it offers excellent power supply rejection ratio and excellent thermal performance for low-power and low current loads.
