MIC3775  
750mA µCap Low-Voltage Low-Dropout Regulator  
Final  
General Description  
Features  
The MIC3775 is a 750mA low-dropout linear voltage regula-  
tors that provides low-voltage, high-current output from an  
extremely small package. Utilizing Micrel’s proprietary  
Superβeta PNP™ pass element, the MIC3775 offers ex-  
tremely low-dropout (typically 280mV at 750mA) and low  
ground current (typically 7.5mA at 750mA).  
• Fixed and adjustable output voltages to 1.24V  
• 280mV typical dropout at 750mA  
Ideal for 3.0V to 2.5V conversion  
Ideal for 2.5V to 1.8V or 1.65V conversion  
• Stable with ceramic capacitor  
• 750mA minimum guaranteed output current  
• 1% initial accuracy  
• Low ground current  
• Current limiting and thermal shutdown  
• Reversed-leakage protection  
TheMIC3775isidealforPCadd-incardsthatneedtoconvert  
fromstandard5Vto3.3Vor3.0V, 3.3Vto2.5Vor2.5Vto1.8V  
or 1.65V. A guaranteed maximum dropout voltage of 500mV  
over all operating conditions allows the MIC3775 to provide  
2.5V from a supply as low as 3.0V and 1.8V or 1.5V from a  
supply as low as 2.25V.  
• Fast transient response  
• Low-profile power MSOP-8 package  
The MIC3775 is fully protected with overcurrent limiting,  
thermal shutdown, and reversed-leakage protection. Fixed  
and adjustable output voltage options are available with an  
operating temperature range of –40°C to +125°C.  
Applications  
• Fiber optic modules  
• LDO linear regulator for PC add-in cards  
• PowerPC™ power supplies  
For other voltages, contact Micrel.  
• High-efficiency linear power supplies  
• SMPS post regulator  
• Multimedia and PC processor supplies  
• Battery chargers  
• Low-voltage microcontrollers and digital logic
