Overview
The NCV5500DT33RKG is a low dropout (LDO) linear voltage regulator produced by ON Semiconductor. This regulator is designed to provide up to 500 mA of output current with a fixed output voltage of 3.3 V. It features an internal PNP pass transistor, which allows for low dropout voltage and operation at full load current even at the minimum input voltage. The NCV5500 series is qualified for demanding automotive applications, requiring extended temperature operation and site and change control, and is also suitable for industrial and consumer applications. The regulator includes an Enable/Shutdown function and is available in DPAK-5 and SOIC-8 packages.
