SM72238  
SolarMagic Micropower Voltage Regulator  
General Description  
Features  
The SM72238 is a micropower voltage regulator with very low  
quiescent current (75μA typ.) and very low dropout voltage  
(typ. 40mV at light loads and 380mV at 100mA). It is ideally  
suited for use in battery-powered systems. Furthermore, the  
quiescent current of the SM72238 increases only slightly in  
dropout, prolonging battery life.  
Renewable Energy Grade  
High accuracy output voltage  
Guaranteed 100mA output current  
Extremely low quiescent current  
Low dropout voltage  
Extremely tight load and line regulation  
The SM72238 is available in the surface-mount D-Pak pack-  
age.  
Very low temperature coefficient  
Careful design of the SM72238 has minimized all contribu-  
tions to the error budget. This includes a tight initial tolerance  
(.5% typ.), extremely good load and line regulation (.05% typ.)  
and a very low output voltage temperature coefficient, making  
the part useful as a low-power voltage reference.  
Use as Regulator or Reference  
Needs minimum capacitance for stability  
Current and Thermal Limiting  
Stable with low-ESR output capacitors (10mto 6Ω)
