ADJUSTMENT RESISTOR VALUES FOR Vo
1
Bus
PT4850 Series
Notes:
1. Use only a single 1% (or better) tolerance resistor in
either the R1 or (R2) location to adjust a specific output.
Place the resistor as close to the ISR as possible.
2. Never connect capacitors to any of the ‘Vox Adj’ pins. Any
capacitance added to these control pins will affect the
stability of the respective regulated output.
3. Adjustments made to any output must also comply with
the following limitations.
Vo1
≥ (Vo2 + 0.5V), and
Vo1
≥ (Vo3 + 0.5V)
R1 = Black, R2 = (Blue)
