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.
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 (isolated), TO-3, TO-66, and
TO-39 power packages.

(Unless otherwise specified, these specifications apply over full operating ambient temperatures for SG140-06 with -55°C ≤ TA ≤ 150°C, and VIN = 11V,
IO = 500mA, CIN = 0. 33µF, COUT = 0.1µF and are applicable for the K, R, and IG - Power package - only. Low duty cycle pulse testing techniques are
used which maintains junction and case temperature equal to the ambient temperature.)
