Positive 2.5V 1A LDO regulator, featuring a 6-pin DFN EP package with exposed pad for surface mounting. This integrated circuit offers a fixed output voltage of 2.5V and a maximum output current of 1A, with a low dropout voltage of 0.2V at 1A. Operating from a 1.5V to 5.5V input, it provides ±2% output voltage accuracy and includes current limit and thermal protection. The compact 3x3x0.88mm plastic package ensures efficient heat dissipation with a junction-to-case thermal resistance of 10°C/W.
