|
|
||||||
The MC78LC00 series voltage regulators are specifically designed for |
MICROPOWER ULTRA±LOW |
||||||
use as a power source for video instruments, handheld communication |
|||||||
equipment, and battery powered equipment. |
QUIESCENT CURRENT |
||||||
The MC78LC00 series features an ultra±low quiescent current of 1.1 μA |
|||||||
VOLTAGE REGULATORS |
|||||||
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 |
SEMICONDUCTOR |
||||||
SOT±23, 5 pin, surface mount packages. |

MOTOROLA ANALOG IC DEVICE DATA |
MC78LC00 Series
DEFINITIONS
Dropout Voltage ± The input/output voltage differential at which the regulator output no longer maintains regulation against further reductions in input voltage. Measured when the output drops 100 mV below its nominal value (which is measured at 1.0 V differential), dropout voltage is affected by junction temperature, load current and minimum input supply requirements.
Line Regulation ± The change in output voltage for a change in input voltage. The measurement is made under conditions
of low dissipation or by using pulse techniques such that average chip temperature is not significantly affected.
Load Regulation ± The change in output voltage for a change in load current at constant chip temperature.
Maximum Power Dissipation ± The maximum total device dissipation for which the regulator will operate within specifications.
Quiescent Bias Current ± Current which is used to operate the regulator chip and is not delivered to the load.
