The trimming (adjust) input on the device allows
output voltage adjustment from 0.75V to 3.3Vdc
(NNL05-9C) or 5.0 (NNL05-0C) by using a resistor
as shown in fig. or by applying a voltage between
trim and common pins as shown in fig.2.
To calculate the resistor value for NNL05-9C:
RTRIM =
2070
– 50 Ω
VOUT – 0.7525
To calculate the resistor value for NNL05-0C:
RTRIM =
0500
– 000 Ω
VOUT – 0.7525
To calculate VTRIM for NNL05-9C:
VTRIM = (0.7–0.698 x {VOUT – 0.7525})
To calculate VTRIM for NNL05-0C:
VTRIM = (0.7–0.0667 x {VOUT – 0.7525})
Tables  & 2 provide RTRIM and VTRIM Values for the
most commonly required output voltages.
