MC78LC00/D

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.
