3 / 12 page MIC2937A/29371/29372 Micrel, Inc. May 2006 3 MIC2937A/29371/29372 Electrical Characteristics Limits in standard typeface are for T J = 25°C and limits in boldface apply over the full operating temperature range. Unless other- wise specified, V IN = VOUT + 1V, IL = 5mA, CL = 10µF. The MIC29372 are programmed for a 5V output voltage, and VSHUTDOWN ≤ 0.6V (MIC29371-xx and MIC29372 only).
