2 / 13 page Data Sheet 2 Rev. 2.3, 2008-03-10 TLE 4274 / 3.3V;2.5V Circuit Description The control amplifier compares a reference voltage to a voltage that is proportional to the output voltage and drives the base of the series transistor via a buffer. Saturation control as a function of the load current prevents any oversaturation of the power element. The IC also includes a number of internal circuits for protection against: • Overload • Overtemperature • Reverse polarity Figure 1 Pin Configuration (top view) Table 1 Pin Definitions and Functions Pin No. Symbol Function 1I Input; block to ground directly at the IC with a ceramic capacitor. 2, 4 GND Ground; PG-TO252-3-11: internally connected to heatsink 3Q Output; block to ground with capacitor C Q ≥ 10 µF, ESR ≤ 2.5 Ω AEP02561 13 Ι Q GND 1 2 3 4 Ι GND GND AEP02282 Q PG-SOT223-4 PG-TO252-3-11 (D-PAK) |
