TS1123 Ultra Low Dropout Voltage Regulator Driver with Enable Function SOT-25 Pin Definition: 1. Output 2. Ground 3. Enable 4. Input 5. Drive General Description TS1123 is a low dropout voltage regulator driver for various electronic equipments. It provides constant voltage power source with SOT-25 package. TS1123 with external PNP transistor can drive output current up to 4A, quiescent current is typically at 5mA. Further more, the quiescent current is smaller when the regulator is in the dropout mode (VIN<5.5V). TS1123 has various functions such as a over current protection, thermal shutdown and an output enable function. Features ● ● ● ● ● Ordering Information Ultra Low Dropout performance 0.5Vmax.
