MC78LC00 Datasheet, PDF (1/8 Pages) Motorola, Inc – MICROPOWER ULTRA-LOW QUIESCENT CURRENT VOLTAGE REGULATORS

Advance Information
Micropower Voltage Regulator
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 µA
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 µA Typical
• Low Dropout Voltage (220 mV at 10 mA)
• Excellent Line Regulation (0.1%)
• High Accuracy Output Voltage (±2.5%)
• Wide Output Voltage Range (2.0 V to 6.0 V)
• Output Current for Low Power (up to 80 mA)
• Two Surface Mount Packages (SOT–89, 3 Pin, or SOT–23, 5 Pin)
