POWER AMPLIFIER REGULATOR CONTROL LINE
The APEX LT module includes a separate 1.8V regulator for a power amplifier bias that enables consistent module out-
put performance over the wide 2.1 – 3.6 V voltage range. To prevent excessive sleep currents, this regulator should be
disabled when the module is in sleep mode. An external pull up resistor option is provided on each module (R6) that allows
the regulator to be constantly enabled. This option increases the sleep current of the module to a point well above the
specified values.
On the APEX LT module the VPA_EN control must be provided by the host microprocessor. In normal operation, the VPA_
EN line must be set high. It must be set low when the module is put into sleep mode in conjunction with putting the EM260
into deep sleep. Upon module wake-up, a 250 µsec turn-on time must be provided prior to any transmission, allowing the
module’s regulator to settle. Note that this 250µsec requirement applies only to the external power amplifier, the wake-up
time for the EM260 is separate from this value.
If the application does not put the module to sleep or if sleep current is not an issue, the power amplifier regulator may
be permanently enabled by tying the control line high. In this setup, the sleep current will increase by 80 µA over the 5µA
Standby Current figure provided in Electrical Specifications.
