Electrical Characteristics (Continued)

Limits in standard typeface are for T_j= 25˚C, and limits in boldface type apply over the full operating junction temperature

range. Unless otherwise specified, V_IN= V_O(NOM)+ 1V, (Note 16), C_OUT= 1µF, I_OUT= 1mA, C_IN= 1µF, V_SD1= V_SD2= V_IN

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

= 235˚C/W, junction-to-ambient. Please refer to the applications section on maximum current capability for further information. The device has internal thermal

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 and V

terminals that is normally reverse-biased. Reversing the polarity from V and V

IN OUT

OUT

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 /∆I

is equal to the

O1 OUT2

specification for ∆V /∆I

O2 OUT1

Note 11: Error Flag threshold and hysteresis are specified as the percentage below the regulated output voltage.
