MIC5203  
µCap™ 80mA Low-Dropout Voltage Regulator  
General Description  
Features  
The MIC5203 is a µCap™ 80mA linear voltage regulator with  
very low dropout voltage (typically 20mV at light loads and  
300mV at 80mA) and very low ground current (225µA at  
20mA output), offering better than 3% initial accuracy with a  
logic-compatible enable input.  
• Tiny 4-lead and 5-lead surface-mount packages  
• Wide Selection of output voltages  
• Guaranteed 80mA output  
• Low quiescent current  
• Low dropout voltage  
• Tight load and line regulation  
• Low temperature coefficient  
• Current and thermal limiting  
• Reversed input polarity protection  
• Zero off-mode current  
The µCap™ regulator design is optimized to work with low-  
value, low-cost ceramic capacitors. The outputs typically  
require only 0.47µF of output capacitance for stability.  
Designedespeciallyforhand-held,battery-powereddevices,  
theMIC5203canbecontrolledbyaCMOSorTTLcompatible  
logicsignal.Whendisabled,powerconsumptiondropsnearly  
to zero. If on-off control is not required, the enable pin may be  
tied to the input for 3-terminal operation. The ground current  
of the MIC5203 increases only slightly in dropout, further  
prolongingbatterylife. KeyMIC5203featuresincludecurrent  
limiting, overtemperature shutdown, and protection against  
reversed battery.  
• Logic-controlled shutdown  
• Stability with low-ESR ceramic capacitors

Applications  
• Cellular telephones  
• Laptop, notebook, and palmtop computers  
• Battery-powered equipment  
• Bar code scanners  
• SMPS post-regulator/dc-to-dc modules  
• High-efficiency linear power supplies  
The MIC5203 is available in 2.8V, 3.0V, 3.3V, 3.6V, 3.8V,  
4.0V, 4.5V, 4.75V, and 5.0V fixed voltages. Other voltages  
are available; contact Micrel for details.
