Note 1: Output voltage temperature coefficients defined as the worst case voltage change divided by the total
Note 2: Unless otherwise specified all limits guaranteed for T
Note 3: Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes
Note 4: Line regulation for the TS2951 is tested at 85
Note 5: Dropout Voltage is defined as the input to output differential at which the output voltage drops 100mV below
Note 6: Vref ≤ Vout ≤ (Vin-1V), 2.3≤ Vin≤ 30V, 100uA≤ I
Note 7: reference voltage temperature coefficient is defined as the worst case voltage change divided by the total
Note 8: Comparator thresholds are expressed in terms of a voltage differential at the feedback terminal below the

its nominal value measured at 1V differential at very low value of programmed output voltage, the minimum
input supply voltage of 2V (2.3V over temperature) must be taken in to account.

nominal reference voltage measured at 6V input. To express these thresholds in terms of output voltage
change, multiply by the error amplifier gain= Vout / Vref = (R1+R2) / R2. For example, at a programmed
output voltage of 5V, the Error output is guaranteed to go low when the output drops by 95 mV X 5V / 1.250 =
384mV. Thresholds remain constant as a percent of Vout as Vout is varied with the dropout warning occurring
at typically 5% below nominal, 7.5% guaranteed.
