2.3 4.75V
This section describes line and load characteristics of the 4.75V output which may be used to supply
external devices. As will be shown, up to 50 mA may be drawn from this output. This seems a reasonable
limit when keeping in mind that battery life with an external device should still amount to several hours.
The 4.75V output voltage is generated inside the 6150AD out of the battery voltage by means of a
switched regulator. It is individually tested in serial production to be in the range of 4.65V to 4.90V with a
typical value of 4.75V (at an input battery voltage of 7.0V).
