Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating the

device outside of its rated operating conditions.

Note 2: ESD testing was performed using Human Body Model, a 100 pF capacitor discharged through a 1.5 k

Ω resistor.

The value of

60˚C/W for the PSOP-8 and 40˚C/W for the LLP-8 package. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the

regulator will go into thermal shutdown.

Note 4: If used in a dual-supply system where the regulator load is returned to a negative supply, the LP3879 output must be diode-clamped to ground.

Note 6: Limits are guaranteed through testing, statistical correlation, or design.

Note 7: Typical numbers reperesent the most likely norm for 25˚C operation.
