Texas Instruments LP38859S-1-2 is a positive fixed linear voltage regulator with a 1.2V output and a 3A maximum output current. This device features a low dropout voltage of 0.45V at 3A and a quiescent current of 8.5mA. The LP38859S-1-2 offers robust protection with over current, over temperature, short circuit, and under voltage lockout (UVLO) capabilities. It also includes a soft start feature for controlled power-up sequences. With a wide operating temperature range of -40°C to 125°C, this regulator is suitable for demanding applications. The TO-263 (DDPAK-5) package facilitates efficient surface mounting. Applications include automotive, industrial power supplies, and high-performance computing.
