Operation
The STM1066 connects or disconnects the output OUT, from the V
logical combination of the enable input (EN), the inhibit input (INH), and the supply voltage
level, V
Output, OUT
If the enable input is in a logic high state and inhibit input is in a logic low state, the output
will be connected to V
output is connected to ground GND. The output is current limited (see
Enable input, EN
A Logic low on the enable input disconnects the output from V
which enters a standby mode with very low current consumption (see
Inhibit input, INH
A logic high on the inhibit input disconnects the output from V
