REG1117A-2.5The REG1117A-2.5 is a 2.5V fixed output low-dropout (LDO) Linear Regulator. The device low-dropout (LDO) voltage allows its use with as little as 1V input-output voltage differential. Laser trimming assures excellent output voltage accuracy without adjustment. An NPN output stage allows output stage drive to contribute to the load current for maximum efficiency., ±1% Output tolerance, Internal current limit, Thermal overload protection, Green product and no Sb/Br
