General Description
The TS178RL00 Series is a low-dropout voltage regulator suitable for various electronic equipments. It provides
constant voltage power source with ITO-220-4L full mold package and TO-252-5L.
Dropout voltage of TS178RL00 Series is below 0.5V in full rated current (1A). This regulator has various functions
such as a peak current protection, thermal shut down, over voltage protection and an output disable function.
