Note 1: Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating ratings indicate conditions for which the device is
intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see Electrical characteristics. The
guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed
test conditions.
Note 2: At elevated temperatures, devices must be derated based on package thermal resistance. The device in the surface-mount package must be derated at
θ
protection.
Note 3: The human body model is a 100pF capacitor discharged through a 1.5kΩ resistor into each pin.
Note 4: : Typical numbers are at 25˚C and represent the most likely parametric norm.
Note 5: : Limits are 100% production tested at 25˚C. Limits over the operating temperature range are guaranteed through correlation using Statistical Quality Control
(SQC) methods. The limits are used to calculate National’s Averaging Outgoing Quality Level (AOQL).
Note 6: If used in a dual-supply system where the regulator load is returned to a negative supply, the LP2966 output must be diode-clamped to ground.
Note 7: The output PMOS structure contains a diode between the V
will turn on this diode.
Note 8: Output voltage line regulation is defined as the change in output voltage from the nominal value due to change in input line voltage.
Note 9: Output voltage load regulation is defined as the change in output voltage from the nominal value when the load current changes from 1mA to 100mA.
Note 10: Output voltage cross regulation is defined as the percentage change in the output voltage from the nominal value at one output when the load current
changes from 1mA to full load in the other output. This is an important parameter in multiple output regulators. The specification for ∆V
specification for ∆V
Note 11: Error Flag threshold and hysteresis are specified as the percentage below the regulated output voltage.
Note 12: Dropout voltage is defined as the input to output differential at which the output voltage drops 100mV below the nominal value. Drop-out voltage
specification applies only to output voltages greater than 2.7V. For output voltages below 2.7V, the drop-out voltage is nothing but the input to output differential, since
the minimum input voltage is 2.7V.
