| 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 Ultra Low Dropout performance 0.5Vmax. Over Current Protection & Thermal Shutdown Short Circuit Protection Output Enable Function 2.4% Typical Total output Ordering Information Part No. Package Packing TS1123CX5xx C0 SOT-25 3Kpcs / 7" Reel Note: Where xx denotes voltage option, 33=3.3V 50=5.0V 80=8.0V 90=9.0V 12=12V 15=15V Block Diagram Absolute Maximum Rating Parameter Input Voltage Enable Voltage Output Current Power Dissipation Junction Temperature Operating Temperature Range Storage Temperature Range 1/4 Symbol VIN VEN IOUT PD TJ TOPR TSTG Value 35 35 200 Internal Limited +150 -40 ~ +125 -65 ~ +150 Unit V V mA C C C Version: A07 TS1123 Ultra Low Dropout Voltage Regulator Driver with Enable Function Electrical Specifications (IO=100mA, Ta=25C, unless otherwise specified).
