Output Trimming
Both the 3.3V and 2.5V outputs of the BCP Series can be independently
trimmed via a trimpot (Figure 3A) or a single xed resistor as shown (Figures
3B & 3C). The trimpot can be used to determine the value of a single xed
resistor. A single xed resistor can increase or decrease the output voltage
depending on its connection. Fixed resistors should have absolute TCR’s
less than 100ppm/°C to ensure stability.
Figure 3A. Trim Connections Using a Trimpot
Figure 3B. Increase Output Voltage Trim Connections Using a Fixed Resistor
A resistor connected from the Trim Pin (pin 5 for 3.3V trim, pin 8 for 2.5V
trim) to the appropriate Return (pin 6 for 3.3V trim, pin 9 for 2.5V trim) will
increase the output voltage.
A single resistor connected from the Trim Pin (pin 5 for 3.3V trim, pin 8 for
2.5V trim) to its appropriate +Output (pin 7 for 3.3V trim, pin 10 for 2.5V trim)
will decrease the output voltage.
