100mA Low-Dropout Voltage Regulator
Preliminary Information
General Description
Features
The MIC5200 is an efficient linear voltage regulator with very _{• High output voltage accuracy}
low dropout voltage (typically 17mV at light loads and 200mV _{• Variety of output voltages}
at 100mA), and very low ground current (1mA at 100mA _{• Guaranteed 100mA output}
output), offering better than 1% initial accuracy with a logic _{• Low quiescent current}
compatible ON/OFF switching input. Designed especially for _{• Low dropout voltage}
hand-held battery powered devices, the MIC5200 is switched _{• Extremely tight load and line regulation}
by a CMOS or TTL compatible logic signal. The ENABLE _{• Very low temperature coefficient}
control may be tied directly to V_IN if unneeded. When disabled, _{• Current and thermal limiting}
power consumption drops nearly to zero. The ground current _{• Zero OFF mode current}
of the MIC5200 increases only slightly in dropout, further _{• Logic-controlled electronic shutdown}
prolonging battery life. Key MIC5200 features include protec- _{• Available in 8-lead SOIC, MM8™ 8-lead MSOP,}
tion against reversed battery, current limiting, and over-
and SOT-223 packages
temperature shutdown.
The MIC5200 is available in several fixed voltages and
