Connections for single output models without sensing or external trimming:
For proper operation, externally connect Pin 5 (+Trim Down) to Pin 8 (+Vout
and Pin 7 (-Trim Up) to Pin 9 (-Vout).
External Output Trimming
Output may optionally be externally trimmed ( 10%)
a fixed resistor or an estimate trimpot as shown.
