CAUTION: To retain proper regulation, do not exceed the 5 Volt output.
Voltage Trim
The LSM-T/16-D12 may also be trimmed using an external voltage applied
between the Trim Input and Output Common. Be aware that the internal “l(fā)oad”
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:
VTRIM = 0.7 – (0.0667 × (VO – 0.7525))

“T” Model LSM-T/16-D12
This version of the LSM 16A series offers a special output voltage trimming
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
(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.
As with other trim adjustments, use a 1% metal lm precision resistor with
low temperature coefcient (±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 LSM-T/16-D12 is as follows:
Figure 7. Trim Connections Using Fixed Resistors
The equations below can be starting points for selecting specic trim-resistor
values. Recall, untrimmed devices are guaranteed to be ±1.25% accurate.
Adjustment beyond the specied ±10% adjustment range is not recom-
mended. When using trim in combination with Remote Sense, the maximum
rated power must not be exceeded (see Remote Sense).
Trim Equations
Note: Resistor values are in k
Ω. Accuracy of adjustment is subject
to tolerances of resistors and factory-adjusted, initial output accuracy.
VO = desired output voltage. VONOM = nominal output voltage.
