SG78xxA/78xx
Positive Fixed
Voltage Regulator
Description
The SG78xxA/SG78xx series of positive regulators offer self-contained, fixed-
voltage capability with up to 1.
5 A of load current and input
voltage up to 50 V (SG78xxA series only).
These units feature a unique on-chip trimming system to set the output
voltages to within ±1.
5% of nominal on the SG78xxA series with ±2.
0% on the SG78xx series.
The SG78xxA versions also offer much improved line and load regulation characteristics.
Utilizing an improved bandgap reference design, problems such as drift in output
voltage and large changes in the line and load regulation, that are normally associated with the Zener diode references have bee...
