SG140A/SG140
POSITIVE FIXED
VOLTAGE REGULATOR
DESCRIPTION
The SG140A/140 series of positive regulators offer self contained, fixed-
voltage capability with up to 1.
5A of load current and input
voltage up to 50V (SG140A series only).
These units feature a unique on-chip trimming system to set the output
voltages to within ±1.
5% of nominal on the SG140A series and ±2.
0% on the SG140 series.
The SG140A versions also offer much improved line and load regulation characteristics.
Utilizing an improved Bandgap reference design, problems have been eliminated that are normally associated with the Zener Diode references, such as drift in output
voltage and large changes in the line and load regulation...
