PIN DESCRIPTIONS
Function
Input Supply pin
Active low shutdown pin for output 1
Active low shutdown pin for output 2
Ground
Error flag for output 2 - Normally high impedance, should be connected to ground if not used.
Error flag for output 1 - Normally high impedance, should be connected to ground if not used.
Output 2
Output 1
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(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 ensure specific performance limits. For ensured specifications and test
conditions, see ELECTRICAL CHARACTERISTICS. The ensured specifications apply only for the test conditions listed. Some
performance characteristics may degrade when the device is not operated under the listed test conditions.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(3) At elevated temperatures, devices must be derated based on package thermal resistance. The device in the surface-mount package
must be derated at θ_jA = 235°C/W, junction-to-ambient. Please refer to APPLICATIONS INFORMATION: Maximum Current Capability
for further information. The device has internal thermal protection.
(4) The human body model is a 100pF capacitor discharged through a 1.5kΩ resistor into each pin.
(5) 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.
(6) The output PMOS structure contains a diode between the V_IN and V_OUT terminals that is normally reverse-biased. Reversing the polarity
from V_IN and V_OUT will turn on this diode.
