13.0
The PIC12HV609/HV615 devices include a permanent
internal 5 volt (nominal) shunt regulator in parallel with
the V
voltage
unregulated supply. All external devices connected
directly to the V
voltage and contribute to the total V
(I
13.1
A shunt regulator generates a specific supply voltage
by creating a voltage drop across a pass resistor R
The voltage at the V
monitored and compared to an internal voltage refer-
ence. The current through the resistor is then adjusted,
based on the result of the comparison, to produce a
voltage drop equal to the difference between the supply
voltage V
See Figure 13-1 for voltage regulator schematic.

The supply voltage V

is limited. Selecting a value for R
three factors into consideration.
Since the regulator uses the band gap voltage as the
regulated voltage reference, this voltage reference is
permanently enabled in the PIC12HV609/HV615
devices.
The shunt regulator will still consume current when
below operating voltage range for the shunt regulator.

managing current load, see Application Note AN1035,
