**LT3062EDCB#TRMPBF: A 45V, 200mA Low Noise LDO Linear Regulator with Programmable Current Limit**
In the realm of power management, achieving clean, stable, and reliable voltage regulation from potentially noisy and variable input sources is a persistent challenge. The **LT3062EDCB#TRMPBF** from Analog Devices addresses this challenge head-on, establishing itself as a premier solution for high-performance applications. This low dropout (LDO) linear regulator combines high input voltage capability with ultra-low noise output and a unique programmable current limit feature.
A standout characteristic of the LT3062 is its **exceptally wide input voltage range of up to 45V**. This allows it to withstand significant voltage transients and be used directly from high-voltage rails, such as 24V industrial supplies or automotive systems, without the need for pre-regulation. Despite this high voltage capability, it delivers a stable **output current of up to 200mA**, making it suitable for powering sensitive analog circuitry, precision sensors, and RF modules.
**Ultra-low output noise is a cornerstone of its performance**. With a noise spectral density of just 30µVRMS (10Hz to 100kHz), the LT3062 ensures that even the most noise-sensitive components, such as high-resolution ADCs, DACs, and PLLs, receive a clean power supply. This is further enhanced by the ability to add an external bypass capacitor to the reference circuit, which can reduce output noise to a mere 20µVRMS.
Beyond noise performance, the regulator offers **excellent line and load regulation**, maintaining a stable output despite fluctuations in input voltage or load current. Its low dropout voltage of typically 300mV at 200mA maximizes efficiency and extends battery life in portable equipment.
A defining feature that sets the LT3062 apart is its **programmable current limit**. By simply adding a single external resistor, designers can set the current limit threshold anywhere from 20mA to 200mA. This provides crucial flexibility for protecting both the regulator and the delicate load circuitry from damage due to fault conditions, a critical requirement in robust system design.
Housed in a compact 6-Lead DFN package, the **LT3062EDCB#TRMPBF** also incorporates essential protection features like internal current limit, thermal shutdown, and reverse battery protection.
**ICGOODFIND**: The LT3062EDCB#TRMPBF is an elite LDO regulator that excels in demanding environments. Its combination of a **45V input rating**, **200mA output**, **ultra-low noise**, and a **programmable current limit** makes it an indispensable component for designing reliable power systems in automotive, industrial, telecommunications, and medical equipment.
