• Description: 100mA LOW DROPOUT VOLTAGE REGULATORS
• Manufacturer: HTC [HTC Korea TAEJIN Technology Co.]

Note 1 : Output or reference voltage temperature coefficients defined as the worst case voltage change divided by the total temperature range.
Note 2 : Unless otherwise specified all limits guaranteed for T
Note 3 : Regulations is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output voltage due
Note 4 : Dropout voltage is defined as the input to output differential at which the output voltage drops 100 ㎷ below its nominal value measured
Note 5 : V
Note 6 : Comparator thresholds are expressed in terms of a voltage differential at the feedback terminal below the nominal reference voltage
Note 7 : V
