The Trim Down resistor should be connected between the Trim pin and Ground pin. The Trim Up resistor should be connected between the Trim pin and the Vout. Only one of the resistors should be used for any given application. 1) Trim Equations for Vo=1.2 V Note : Vo_req=Desired (trimmed) output voltage [V] Vo=1.202 V 2) Trim Equations for Vo=1.5 V - 12 V Note : Vo_req=Desired (trimmed) output voltage [V] Vo=1.503V, Vo=1.800V, Vo=2.505V, Vo=3.308V, Vo=5.002V, Vo=12.007V 22 . 10 511 − = delta Rtrimdown () [] % 100 _ × − = Vo Vo req Vo delta 22 . 10 225 . 1 626 511 ) 100 ( − ⋅ − ⋅ ⋅ + = delta Vo delta Rtrimup Rtrimdown Vo Trim GND Module 22 . 10 511 − = delta Rtrimdown () [] % 100 _ × − = Vo Vo req Vo delta Vo Trim GND Module Rtrimup 22 . 10 6125 . 0 313 11 . 5 ) 100 ( − ⋅ − ⋅ ⋅ + = delta Vo delta Rtrimup |
