It provides constant voltage power source with surface-mount type package (DPAK). The dropout voltage is below 0.6 V in full-rated current 0.5 A. This regulator has over-current protection, thermal shut-down and the SOA (Safe operating Area) protection. 0.5 A / 3.3 V Output Low-Dropout Voltage Regulator Low-Dropout Voltage (Max: 0.6 V) Over-Current Protection, Thermal Shutdown SOA Protection, Short-Circuit Protection DPAK 1 2 3 1.

The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Values are at TA = 25°C unless otherwise noted.
