com SG7800A/SG7800 SERIES SG7800A/SG7800 POSITIVE FIXED VOLTAGE REGULATOR DESCRIPTION The SG7800A/SG7800 series of positive regulators offer self contained, fixed-voltage capability with up to 1.
5A of load current and input voltage up to 50V (SG7800A series only).
These units feature a unique on-chip trimming system to set the output voltages to within ±1.
5% of nominal on the SG7800A series,±2.
0% on the SG7800 series.
The SG7800A 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.
All protective features of thermal shutdown, current limiting, and safe-area control have been designed into these units and since these regulators require only a small output capacitor for satisfactory performance, ease of application is assured.
Although designed as fixed-voltage regulators, the output voltage can be increased through the use of a simple voltage divider.
The low quiescent drain current of the device insures good regulation when this method is used.
Product is available in hermetically sealed TO-257, TO-3, TO39 and LCC packages.
