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 F depending on the regulated
voltage;
●
VLINmain_OUT = 0.8 V --> 1 F
●
0.8V< VLINmain_OUT < 2.5 V --> 0.68 F
●
2.5V= VLINmain_OUT 5 V --> 0.33 F
●
VLINmain_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 VSupply. When in this
condition, the output pin is pulled low by an internal switch.
