Product Description

The CM3019 is a CMOS linear voltage regulator with low quiescent current, very low drop out voltage and better than 1 initial output voltage accuracy.

The quiescent current is typically 150μA at light loads and only 165μA at 500mA. This is 5 more efficient than equivalent Bi-CMOS devices that can waste up to 25mA at 500mA.
