Note 1: Output voltage temperature coefficients defined as the worst case voltage change divided by the total
temperature range.

= 100uF. Additional
conditions for the 8-pin versions are feedback tied to 5V, 3.3V & 3V tap output Sense (Vout = 5V, 3.3V & 3V) and
Vshutdown
≤
0.8V.
Note 3: Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in
output voltage due to heating effects are covered under the specification for thermal regulation.
Note 4: Line regulation for the TS2951 is tested at 85

C for I
L
= 1mA.For I
L
= 100uA and Tj= 125
o
C, line regulation is
guaranteed by design to 0.2%.
Note 5: Dropout Voltage is defined as the input to output differential at which the output voltage drops 100mV below 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.

Note 7: reference voltage temperature coefficient is defined as the worst case voltage change divided by the total
temperature range.
Note 8: Comparator thresholds are expressed in terms of a voltage differential at the feedback terminal below the
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.
