Micro Electronics JAN7905K Negative fixed voltage regulator Datasheet

SG7900A/SG7900 SERIES
SG7900A/SG7900
NEGATIVE FIXED VOLTAGE REGULATOR
DESCRIPTION
FEATURES
The SG7900A/SG7900 series of negative regulators offer self-contained,
fixed-voltage capability with up to 1.5A of load current. With a variety of
output voltages and four package options this regulator series is an
optimum complement to the SG7800A/SG7800, SG140 line of three
terminal regulators.

These units feature a unique band gap reference which allows the
SG7900A series to be specified with an output voltage tolerance of ±1.5%.
The SG7900A versions also offer much improved line regulation characteristics.
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 single output capacitor (SG7900 series) or a capacitor and
5mA minimum load (SG120 series) 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, especially for the SG120 series.
Output voltage set internally to ±1.5% on SG7900A
Output current to 1.5A
Excellent line and load regulation
Foldback current limiting
Thermal overload protection
Voltages available: -5V, -12V, -15V
Contact factory for other voltage options
Available in surface mount package
