(also see section 1.0, electrical characteristics ). the output, v out , stays valid until the input voltage falls below the minimum operating voltage, v in min , of 0.7v. below this minimum operating voltage, the output is undefined. during power-up or anytime v in has fallen below v in min , v out will remain undefined until v in rises above v in min , at which time the output becomes valid. v out is maintained in its active low state while v in min ? 2001-2015 microchip technology inc. ds20001430e-page 5 tc52 5.0 packaging information 5.1 package marking information 5-lead sot-23 example n 0c2 standard markings for sot-23 part number code TC52N3027ECTTR n 0c# tc52n4527ecttr n 0p# note : in the event the full microchip part number cannot be marked on one line, it will be carried over to the next line, thus limiting the number of available characters for customer-specific information. legend: xx...x customer-specific information y year code (last digit of calendar year) yy year code (last 2 digits of calendar year) ww week code (week of january 1 is week ?01?) nnn alphanumeric traceability code pb-free jedec designator for matte tin (sn) * this package is pb-free. the pb-free jedec designator ( ) can be found on the outer packaging for this package. 3 e 3 e n-channel indication and integer part of output voltage symbol output n nch registration serial number symbol detected voltage 1 detected voltage 2 0c 3.0 2.7 0p 4.5 2.7 tc52 ds20001430e-page 6 ? 2001-2015 microchip technology inc. ! !
