DESCRIPTION
Input voltage pin
Common ground (device substrate)
Logic high enable input
DO NOT CONNECT. Device pin 4 is reserved for post packaging test and calibration of the
LP2989 VOUT accuracy. Device pin 2 must be left floating. Do not connect to any potential. Do
not connect to ground. Any attempt to do pin continuity testing on device pin 2 is discouraged.
Continuity test results will be variable depending on the actions of the factory calibration.
Aggressive pin continuity testing (high voltage, or high current) on device pin 2 may activate the
trim circuitry forcing VOUT to move out of tolerance.
Regulated output voltage
