Microsemi JAN7812T Positive fixed voltage regulator Datasheet

SG7800A/SG7800 SERIES
SG7800A/SG7800
POSITIVE FIXED VOLTAGE REGULATOR
DESCRIPTION
FEATURES
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.
Output voltage set internally to ±1.5% on SG7800A
Input voltage range to 50V max. on SG7800A
Two volt input-output differential
Excellent line and load regulation
Foldback current limiting
Thermal overload protection
Voltages available: 5V, 12V, 15V
Available in surface mount package

Note A. Junction Temperature Calculation: TJ = TA + (PD x θ JA).
Note B. The above numbers for θJC are maximums for the limiting thermal
resistance of the package in a standard mounting configuration.
The θ JA numbers are meant to be guidelines for the thermal
performance of the device/pc-board system. All of the above
assume no ambient airflow.

SG7800A/SG7800 ........................................ -55°C to 150°C
Note 2. Range over which the device is functional.
CHARACTERISTIC CURVES
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 inputoiutput 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.
