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...
