Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating

Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(1)

All voltages are with respect to GND.

(2)

UA78L regulator doesn't need any external capacitors for the the LDO stability.

(3)

An input capacitor with value of 0.33 μF is recommended to counteract the effect of source resistance and inductance, which can in

some cases cause symptoms of system level instability such as ringing or oscillation, especially in the presence of load transients.

(4)

An output capacitor with value of 0.1 μF is recommended to improve the load and line transient performance of the UA78L regulator.
