FUNCTION
Positive Terminal for C1
Negative Terminal for C1
Negative Output Voltage (unregulated)
Active-Low, TTL Logic-Level Shutdown Input
Dual Mode? Feedback Input. When FB is grounded, the output is preset to -2V. To
select other output voltages, connect FB to an external resistor divider (Figure 2b).
Control Voltage Input. To set V OUT , connect a resistor divider between OUT and a
positive control voltage between 0V and 10V (Figure 2c).
