module includes a regulator that has the capability of going
into Sleep mode by having an Enable terminal. See
When the module’s regulator is in sleep mode, the module is
turned off. The module waits for a defined wake-up voltage
module’s regulator. See

level on the bus. This wake-up voltage will activate the control
line, which enables the regulator and turns the module back
on. This 33897/A/C/T feature allows the module to be more
energy efficient since the current consumption is significantly
lowered when it goes into sleep mode.
is no need for the module to have control over its regulator via
the transceiver.
