APPLICATION INFORMATION
For convenience, a table of standard 1% resistor values
is shown below
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.

Figure 17 – Basic Regulator Circuit
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.

APPLICATION INFORMATION (CONTINUED)
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 20 – Remote Sensing
Figure 23 – 21V Programming Supply for UV Prom/ EEPROM
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

⎠
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.
