PRODUCTION DATA
Device 2 follows the voltage applied to the SS/TR pin. A ramp on SS/TR to 0.8V ramps the output voltage according to the 0.6V reference on VFB.
Tracking the 3.8V of device 1 requires a resistor divider on SS/TR of device 2 to ouput 0.8V when the output voltage divider of device 1 is 0.6V. The output current of 2.5µA from the SS/TR pin cases an offset voltage on the resistor divider formed by R7 and R8. The equivalent resistance of R7 // R8 must therefore be kept below 15kΩ.
