MC78LC00_09 Datasheet, PDF (1/12 Pages) ON Semiconductor – Micropower Voltage Regulator

MC78LC00 Series
Micropower Voltage
Regulator
The MC78LC00 series of fixed output low dropout linear regulators
are designed for handheld communication equipment and portable
battery powered applications which require low quiescent current. The
MC78LC00 series features an ultra−low quiescent current of 1.1 mA.
Each device contains a voltage reference unit, an error amplifier, a
PMOS power transistor, and resistors for setting output voltage.
The MC78LC00 has been designed to be used with low cost ceramic
capacitors and requires a minimum output capacitor of 0.1 mF. The
device is housed in the micro−miniature Thin SOT23−5 surface mount
package and SOT−89, 3 pin. Standard voltage versions are 1.5, 1.8,
2.5, 2.7, 2.8, 3.0, 3.3, 4.0, and 5.0 V. Other voltages are available in
100 mV steps.
Features
• Low Quiescent Current of 1.1 mA Typical
• Excellent Line and Load Regulation
• Maximum Operating Voltage of 12 V
• Low Output Voltage Option
• High Accuracy Output Voltage of 2.5%
• Industrial Temperature Range of −40°C to 85°C
• Two Surface Mount Packages (SOT−89, 3 Pin, or SOT−23, 5 Pin)
• These are Pb−Free Devices
Typical Applications
• Battery Powered Instruments
• Hand−Held Instruments
• Camcorders and Cameras
