MIC5201  
200mA Low-Dropout Regulator  
General Description  
Features  
The MIC5201 is an efficient linear voltage regulator with very  
low dropout voltage (typically 17mV at light loads and 200mV  
at 100mA), and very low ground current (1mA at 100mA  
output), offering better than 1% initial accuracy with a logic  
compatible on-off switching input.  
• High output voltage accuracy  
• Variety of output voltages  
• Guaranteed 200mA output  
• Low quiescent current  
• Low dropout voltage  
• Extremely tight load and line regulation  
• Very low temperature coefficient  
• Current and thermal limiting  
• Reversed-battery protection  
• Load-dump protection (fixed voltage versions)  
• Zero off-mode current  
Designed especially for hand-held battery powered devices,  
the MIC5201 can be switched by a CMOS or TTL compatible  
enable signal. This enable control may be connected directly  
to V if unneeded. When disabled, power consumption  
IN  
drops nearly to zero. The ground current of the MIC5201  
increases only slightly in dropout, further prolonging battery  
life. Key MIC5201 features include current limiting,  
overtemperature shutdown, and protection against reversed  
battery.  
• Logic-controlled electronic enable  
• Available in SO-8 and SOT-223 packages  
Applications  
The MIC5201 is available in several fixed voltages and  
accuracy configurations. It features the same pinout as the  
LT1121withbetterperformance. Otheroptionsareavailable;  
contact Micrel for details.  
• Cellular telephones  
• Laptop, notebook, and palmtop computers  
• Battery powered equipment  
• PCMCIA V and V regulation/switching
