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.

Note 3. Operation at high input voltages is dependent upon load current. When
load current is less than 5mA, output will rise out of regulation as input-
oiutput differential icreases beyond 30V. Note also from Figure 1, that
maximum load current is reduced at high voltages. The 50V input rating
of the SG140A series refers to ability to withstnd high line or transient
conditions without damage. Since the regulator's maximum current
capability is reduced, the output may fall out of regulation at high input
voltages under nominal loading.

ELECTRICAL CHARACTERISTICS (Note 1)
Note 1. All regulation tests are made at constant junction temperature with low duty cycle testing.
2. This test is guaranteed but is not tested in production.
SG140 - 18
(Unless otherwise specified, these specifications apply over full operating ambient temperatures for SG140-18 with -55°C ≤ TA ≤ 150°C, and VIN = 27V,
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.)
