Recommended power transistors
The following NPN transistors are recommended for use with the on-chip voltage regulator
controller: ON SemiconductorTM BCP68T1 or NJD2873 as well as Philips SemiconductorTM
BCP68. The collector of the external transistor is preferably connected to the same voltage
supply source as the output stage of the regulator.

Resistor may or may not be
required. It depends on the
allowable power dissipation
of the npn bypass transistor
device.
Emitter and collector capacitors
(6.8
μF and 10 μF) should be
matched (same type) and ESR
should be lower than 200 m
Ω.
Notes:
1. The VRCCTL capacitor is required.
2. The bypass transistor MUST be operated out of its saturation region.
