IMPORTANT: On W3 models only, for outputs greater than 3 Volts up to 3.3
Volts maximum, the input supply must be 4.5 Volts minimum. To retain proper
regulation, do not exceed the 3.3V output.
As with other trim adjustments, be sure to use a precision low-tempco resis-
tor (±00 ppm/°C) mounted close to the converter with short leads. Also be
aware that the output voltage accuracy is ±2% (typical) therefore you may
need to vary this resistance slightly to achieve your desired output setting.
Two different trim equations are used for the W3 and D2 models.

Voltage Trim
The LSM2 Series 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 5 Kilohms. Therefore, you
may have to compensate for this in the source resistance of your external
voltage reference.
Use a low noise DC reference and short leads. Mount the leads close to the
converter. Consider using a small bypass capacitor (0.F ceramic) between
trim and output common to avoid instability.
Two different trim equations are used for the W3 and D2 models.
W3 Models Voltage Trim Equation:
VTRIM (in Volts) = 0.7 –(0.698 x (VO – 0.7525))
The LSM2 W3 fixed trim voltages to set the output voltage are:
