P-Channel Pass Transistor The MAX1658/MAX1659 feature an internal P-channel MOSFET pass transistor. Using a MOSFET provides several advantages over similar PNP designs, including lower dropout voltage and extended battery life. Unlike bipolar transistors, MOSFETs reduce quiescent current, because they require ...

Input, Low-Dropout Linear Regulators Thermal-Overload Protection Thermal-overload protection limits total power dissipa- tion in the MAX1658/MAX1659. When the junction tem- perature exceeds T = +165°C, the pass transistor J deactivates, allowing the IC to cool. Once it has ...
