PIN DESCRIPTIONS

Pin

Name

Function

1

VIN

Input Supply pin

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.

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

for further information. The device has internal thermal protection.

(4)

The human body model is a 100pF capacitor discharged through a 1.5k

Ω 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.
