Overview
The NCV5501DT33RKG is a low dropout (LDO) linear voltage regulator produced by onsemi. This regulator is capable of providing up to 500 mA of output current over a fixed output voltage of 3.3 V. It features a user-adjustable output range from 1.25 V to 5.0 V, although the specific model NCV5501DT33RKG is fixed at 3.3 V. The regulator includes an internal PNP pass transistor, which allows for low dropout voltage and operation at full load current even at the minimum input voltage. The NCV5501 series is particularly suited for demanding automotive applications due to its extended temperature operation and site and change control qualifications.
