Figure 10. Linear main regulator with external bipolar for high current
Whichever configuration is used (regulator or controller), a ceramic capacitor must be
connected on the output pin towards ground to guarantee the stability of the regulator; the
value of this capacitance is in the range of 100 nF to 1 µF depending on the regulated
voltage;
● V
LINmain_OUT
= 0.8 V --> 1 µF
● 0.8V< V
LINmain_OUT
< 2.5 V --> 0.68 µF
● 2.5V= V
LINmain_OUT
5 V --> 0.33 µF
● V
LINmain_OUT
> 5 V --> 0.1 F
When this regulator is disabled, the whole circuit is switched off and the current
consumption is reduced to a very low level both from V3v3 and from V
Supply
. When in this
condition, the output pin is pulled low by an internal switch.
