UA78M33QDCYRG4Q1 General Description

This series of fixed-voltage integrated-circuit voltage regulators is designed for a wide range of applications. These applications include on-card regulation for elimination of noise and distribution problems associated with single-point regulation. Each of these regulators can deliver up to 500 mA of output current. The internal current-limiting and thermal-shutdown features of these regulators essentially make them immune to overload. In addition to use as fixed-voltage regulators, these devices can be used with external components to obtain adjustable output voltages and currents and also as the power-pass element in precision regulators.

Ratings and Reviews

W**t 12/27/2021

From 10.04.19 to 6.06.19, in goose-crystal, from the moment of order. Warm-white is yellow, in the entrance or the trunk will go, but for the workplace there is no, you need white-white. One led, ktati, put white. Heated like a frying pan. The crystals in the matrix 3x3 do not work evenly over the voltage. With my t5st it turned out 10-11 v, 200-600 ma.
