MIC5237  
500mA Low-Dropout Regulator  
Preliminary Information  
General Description  
Features  
The MIC5237 is a general-purpose low-dropout regulator  
capable of 500mA output current with better than 3% output  
voltage accuracy. Using Micrel’s proprietary Super  
ßeta PNP™ process with a PNP pass element, these regu-  
lators feature less than 300mV dropout voltage and typically  
8mA ground current at full load.  
• Guaranteed 500mA output over the full operating  
temperature range  
• Low 300mV typical dropout voltage at full load  
• Extremely tight load and line regulation  
• Current and thermal limiting  
• Reversed-battery protection  
• TO-220 and TO-263 packages  
• Low temperature coefficient  
• No-load stability  
Designed for applications that require moderate current over  
abroadinputvoltagerange, includinghand-heldandbattery-  
powered devices, the MIC5237 is intended for applications  
that can tolerate moderate voltage drop at higher current.  
• Low-noise output  
Applications  
• Portable and laptop computers  
• Desktop computer  
Key features include low ground current to help prolong  
batterylife,reversed-batteryprotection,currentlimiting,over-  
temperature shutdown, and thermally efficient packaging.  
The MIC5237 is available in fixed output voltages only.  
• Battery chargers  
For space-critical applications and improved performance,  
see the MIC5209 and MIC5219. For output current require-  
ments up to 750mA, see the MIC2937.  
• SMPS post-regulator/dc-to-dc modules  
• Consumer and personal electronics
