Linear Technology LT3013BEDE: High Voltage, Micropower Low Dropout Regulator

The LT3013BEDE is a robust, high-performance low dropout linear regulator (LDO) designed by Linear Technology, now part of Analog Devices. This versatile component is engineered to deliver a continuous output current of up to 250mA with a low dropout voltage, making it an ideal choice for a wide range of applications that require efficient power regulation.

Key to the LT3013BEDE's performance is its ability to operate over a wide input voltage range, from 4V to 80V, which provides flexibility for designers working with high voltage systems. This makes the device particularly suitable for automotive, industrial, and telecommunications applications where input voltages can vary significantly.

One of the standout features of the LT3013BEDE is its low quiescent current of only 50µA, which minimizes power consumption when in operation, and less than 1µA in shutdown mode. This characteristic is especially beneficial for battery-powered and energy-sensitive applications, as it helps extend the operational lifespan of the system.

The LT3013BEDE also boasts excellent stability, being able to operate with a small, low-cost ceramic output capacitor of only 3.3µF. These capacitors are not only cost-effective but also have the advantage of being more reliable over a broader range of environmental conditions compared to tantalum or aluminum electrolytic capacitors.

Protection features of the LT3013BEDE include reverse-battery protection, current limiting, thermal limiting, and the ability to withstand reverse output currents. These safeguards ensure the LDO's reliability and longevity in harsh environments and under abnormal operating conditions.

The device is available in a 12-lead low profile (0.75mm) DFN (4mm x 3mm) package and a 12-lead thermally enhanced MSOP package. Both packages are designed to optimize thermal performance and save space on the PCB, making the LT3013BEDE a compact and efficient solution for space-constrained applications.

With its wide input voltage range, low quiescent current, and robust protection features, the LT3013BEDE from Linear Technology is a top-tier choice for designers seeking a reliable LDO for their high voltage applications.
