| TS178R00 Series ITO-220-4L ITO-220-4SL Pin assignment: 1. Input 2. Output 3. Gnd 4. Enable Preliminary 1A Ultra Low Dropout Voltage Regulator w/Disable Low Dropout Voltage 0.5V max. General Description The TS178R00 Series is a low-dropout voltage regulator suitable for various electronic equipments. It provides constant voltage power source with ITO-220 4 lead full mold package. Dropout voltage of TS178R00 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. Features Ultra Low Dropout performance 0.5Vmax 1A Over Current Protection, Thermal Shutdown Over Voltage Protection, Short Circuit Protection With Output Disable Function 2.4% Typical Total output TO-220 Full-Mold Package (4Pin) Ordering Information Part No. TS178RxxCI4 TS178RxxCI4S Operating Temp.
