Trim Equations
"T" Model LSN-T/16-D12
This version of the LSN 16A series offers a special output voltage trimming
R T UP (k Ω ) =
0.349
V O – V O NOM
– X
feature which is fully compatible with competitive units. The output voltage
may be varied from 0.75 to 5 Volts using a single external trim up resistor con-
nected from the Trim input to Output Common. If no trim resistor is attached
LSN-0.75/16-D12: X = 3.09
LSN-0.75/16-D12 cannot be trimed down
(Trim pin open), the output is 0.7525 Volts.
The trim may also be adjusted using an external reference voltage con-
nected to the Trim input.

R T UP (k Ω ) =

As with other trim adjustments, use a 1% metal ?lm precision resistor with
low temperature coef?cient (±100 ppm/°C or less) mounted close to the con-
verter with short leads. Also be aware that the output accuracy is ±2% (typical)
therefore you may need to vary this resistance slightly to achieve your desired
output setting.
The resistor trim up equation for the LSN-T/16-D12 is as follows:
LSN-1/16-D12: X = 2.67
LSN-1.2/16-D12: X = 4.75
LSN-1.5/16-D12: X = 7.5

CAUTION: To retain proper regulation, do not exceed the 5 Volt output.
LSN-5/16-D12:

Voltage Trim
Note: Resistor values are in kΩ. Accuracy of adjustment is subject to
tolerances of resistors and factory-adjusted, initial output accuracy.
V O = desired output voltage. V ONOM = nominal output voltage.
The LSN-T/16-D12 may also be trimmed using an external voltage applied
between the Trim Input and Output Common. Be aware that the internal “load”
impedance looking into trim pin is approximately 5k Ω . Therefore, you may
have to compensate for this in the source resistance of your external voltage
reference.
The equation for this voltage adjustment is:
V TRIM = 0.7 –(0.0667 × (V O – 0.7525))
