TNY178PN DIP7

1. It is the connection point for an external bypass capacitor
for the internally generated 5.85 V supply.
2. It is a mode selector for the current limit value, depending
on the value of the capacitance added. Use of a 0.1 μF
capacitor results in the standard current limit value. Use of
a 1 μF capacitor results in the current limit being reduced to
that of the next smaller device size. Use of a 10 μF capacitor
results in the current limit being increased to that of the next
larger device size for TNY175-180.
3. It provides a shutdown function. When the current into
the bypass pin exceeds ISD, the device latches off until the
BP/M voltage drops below 4.9 V, during a power down.
This can be used to provide an output overvoltage function
