The MC78LC00 series voltage regulators are specifically designed for
use as a power source for video instruments, handheld communication
equipment, and battery powered equipment.
The MC78LC00 series features an ultra–low quiescent current of 1.1
μ
A
and a high accuracy output voltage. Each device contains a voltage
reference, an error amplifier, a driver transistor and resistors for setting the
output voltage. These devices are available in either SOT–89, 3 pin, or
SOT–23, 5 pin, surface mount packages.
MC78LC00 Series Features:
Low Quiescent Current of 1.1
μ
