General Description
SR78MXXED is three-terminal positive regulators. One of these regulators can deliver up to 1A of
output current.When used as a replacement for a Zener diode-resistor Combination, an effective
improvement in output impedance can be obtained, together with lower quiescent current.

Pin Configuration
Absoulte Maximum Ratings(Ta=25
℃
)
Note:The absolute maximum ratings are rated values exceeding which the product could suffer physical damage. These values must therefore
not be exceeded under any conditions.
Electrical Characteristic(Cin=0.33uF, Co=0.1uF, Ta=25℃，unless otherwise noted)
LNR: Line Regulation. The change in output voltage for a change in the input voltage. The measurement is made under conditions of low
dissipation or by using pulse techniques such that the average chip temperature is not significantly affected.
LDR: Load Regulation.The change in output voltage for a change in load current at constant chip temperature.
PIN NO.
