1.5 AMP THREE TERMINAL
ADJUSTABLE VOLTAGE REGULATOR
DESCRIPTION
FEATURES
The SG117A Series are 3-terminal positive adjustable voltage
regulators which offer improved performance over the original 117
design. A major feature of the SG117A is reference voltage
tolerance guaranteed within ± 1%, allowing an overall power supply
tolerance to be better than 3% using inexpensive 1% resistors. Line
and load regulation performance has been improved as well.
Additionally, the SG117A reference voltage is guaranteed not to
exceed 2% when operating over the full load, line and power
dissipation conditions. The SG117A adjustable regulators offer an
improved solution for all positive voltage regulator requirements
with load currents up to 1.5A.

ELECTRICAL CHARACTERISTICS
(Unless otherwise specified, these specifications apply over full operating ambient temperatures for SG117A/SG117 with -55°C ≤ TA ≤ 125°C, SG217A/
SG217 with -25°C ≤ TA ≤ 150°C, SG 317A/SG317 with 0°C ≤ TA ≤ 125°C, VIN - VOUT = 5.0V , and for IOUT = 500mA (K, R, and IG), and IOUT = 100mA

packages, and 20W for the K, R, and IG packages. IMAX is 1.5A for the K, R, and IG packages and 500mA for the T and L packages. Low duty cycle
pulse testing techniques are used which maintains junction and case temperatures equal to the ambient temperature.)

APPLICATION INFORMATION
GENERAL
The SG117A develops a 1.25V reference voltage between the
output and the adjustable terminal (see Figure 1). By placing a
resistor, R1 between these two terminals, a constant current is
caused to flow through R1 and down through R2 to set the overall
output voltage, Normally this current is the specified minimum
load current of 5mA or 10mA.
For convenience, a table of standard 1% resistor values is shown
below.

Standard Resistance Values are obtained from the Decade
Table by multiplying by multiples of 10. As an example:1.21
can represent 1.21Ω, 12.1Ω, 121Ω, 1.21KΩ etc.
Because IADJ is very small and constant when compared with the
current through R1, it represents a small error and can usually be
ignored.
It is easily seen from the above equation, that even if the resistors
were of exact value, the accuracy of the output is limited by the
accuracy of VREF. Earlier adjustable regulators had a reference
tolerance of ±4%. This tolerance is dangerously close to the ±5%
supply tolerance required in many logic and analog systems.
Further, many 1% resistors can drift 0.01%°C adding another 1%
to the output voltage tolerance.
For example, using 2% resistors and ±4% tolerance for VREF,
calculations will show that the expected range of a 5V regulator
design would be 4.66V ≤ VOUT ≤ 5.36V or approximately ±7%. If
the same example were used for a 15V regulator, the expected
tolerance would be ±8%. With these results most applications
require some method of trimming, usually a trim pot. This solution
is expensive and not conducive to volume production.
FIGURE 18 - CONNECTIONS FOR BEST LOAD REGULATION
One of the enhancements of Silicon General’s adjustable regulators over existing devices is tightened initial tolerance. This
allows relatively inexpensive 1% or 2% film resistors to be used
for R1 and R2 while setting output voltage within an acceptable
tolerance range.
With a guaranteed 1% reference, a 5V power supply design,
using ±2% resistors, would have a worse case manufacturing
tolerance of ±4%. If 1% resistors were used, the tolerance would
drop to ±2.5%. A plot of the worst case output voltage tolerance
as a function of resistor tolerance is shown on the front page.

BYPASS CAPACITORS
Input bypassing using a 1µF tantalum or 25µF electrolytic is
recommended when the input filter capacitors are more than 5
inches from the device. A 0.1µF bypass capacitor on the
ADJUST pin is required if the load current varies by more than 1A/
µsec. Improved ripple rejection (80dB) can be accomplished by
adding a 10µF capacitor from the adjust pin to ground. For
improved AC transient response and to prevent the possibility of
oscillation due to unknown reactive load, a 1µF capacitor is also
recommended at the output. Because of their low impedance at
high frequencies, the best type of capacitor to use is solid
tantalum.

FIGURE 21 - IMPROVING RIPPLE REJECTION
LOAD REGULATION
Because the SG117A is a three-terminal device, it is not possible
to provide true remote load sensing. Load regulation will be
limited by the resistance of the wire connecting the regulator to
the load. For the data sheet specification, regulation is measured
at the bottom of the package. Negative side sensing is a true
Kelvin connection, with the bottom of the output divider returned
to the negative side of the load. Although it may not be immediately obvious, best load regulation is obtained when the top of the
divider is connected directly to the case, not to the load. This is
illustrated in Figure 18. If R1 were connected to the load, the
effective resistance between the regulator and the load would be

P
FIGURE 24 - 2816 EEPROM SUPPLY PROGRAMMER FOR READ/WRITE CONTROL
= Parasitic Line Resistance.
Connected as shown, RP is not multiplied by the divider ratio. RP
is about 0.004Ω per foot using 16 gauge wire. This translates to
4mV/ft. at 1A load current, so it is important to keep the positive
lead between regulator and load as short as possible.
