Texas Instruments LM3480 Fixed LDO Voltage Regulator, 0V to 30V, 100mA, SOT-23 - 3.3V

The Texas Instruments LM3480 series fixed LDO (low dropout) voltage regulators provide a compact, high-performance solution for a wide range of power management applications. Engineered to operate from an input voltage as high as 30V, this regulator ensures a maximum dropout voltage of just 1.2V at the full 100mA load, making it an efficient choice for systems with tight voltage margins.

This device is part of the LM3480 family, which includes 5V, 12V, and 15V fixed-output versions, and serves as a tiny alternative to the industry-standard LM78Lxx series. With a typical dropout voltage of only 900mV, the LM3480 series offers a significant advantage over the 2V to 2.5V dropout of conventional regulators, allowing for better utilisation of supply voltage and reduced power dissipation. The LM3480 series also includes a 3.3V member, which is ideal for bias supplies that regulate directly off a system's 5V ±5% power rail.

This regulator delivers a fixed 12V output with a guaranteed minimum output current of 100mA and an output voltage tolerance of ±5% across full load and temperature ranges. The device is supplied in a space-saving SOT-23 surface-mount package with three pins, making it suitable for compact PCB layouts. It operates over a wide temperature range from -40°C to 125°C, ensuring reliable performance in demanding environments.

As a green product, this regulator is free from antimony (Sb) and bromine (Br), meeting modern environmental standards. Whether used in power management, bias supplies, or as a local voltage regulation point, this LDO regulator offers a dependable, high-quality solution for your design needs.
