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_J= 25°C, V_IN= 6V, I_L= 100µA and C_L= 1µF. Additional conditions for the 8-pin versions are feedback

tied to 5V tap and output tied to output sense (V_OUT= 5V) and V_SHUTDOWN≤ 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 LP2951 is tested at I_L= 1mA. For I_L= 100 µA and T_J= 125°C, line regulation is guaranteed by design to 0.2%. See typical

performance characteristics for line regulation versus temperature and load current.

Note 5: Dropout voltage is defined as the input to output differential at which the output voltage drops 100 mV below its nominal value measured at 1V differential. At

very low values of programmed output voltage, the minimum input supply voltage of 2V (2.3V over temperature) must be taken into account.

Note 6: V_REF≤V_OUT≤ (V_IN- 1V), 2.3 ≤V_IN≤30V, 100µA≤I_L≤ 100mA, T_J≤ T_JMAX

Note 7: 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 = V_OUT/V_REF= (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/1.235 = 384 mV. Thresholds remain constant as a percent of V_OUTas V_OUT

is varied, with the dropout warning occurring at typically 5% below nominal, 7.5% guaranteed.

Note 8: V_SHUTDOWN≥ 2V, V_IN≤ 30V, V_OUT=0, Feedback pin tied to 5V Tap.

Note 9: All typical values are not guaranteed. The value could vary from lot to lot.
