APPLICATIONS INFORMATION
The NCP1086 voltage regulator series provides
adjustable and 3.3 V output voltages at currents up to 1.5 A.
The regulator is protected against overcurrent conditions
and includes thermal shutdown.
The NCP1086 series has a composite PNPNPN output
transistor and requires an output capacitor for stability. A
detailed procedure for selecting this capacitor is included in
the Stability Considerations section.
Adjustable Operation
The adjustable output device has an output voltage range
of 1.25 V to 5.5 V. An external resistor divider sets the
output voltage as shown in Figure 15. The regulator
maintains a fixed 1.25 V (typical) reference between the
output pin and the adjust pin.
A resistor divider network R1 and R2 causes a fixed
current to flow to ground. This current creates a voltage
across R2 that adds to the 1.25 V across R1 and sets the
overall output voltage. The adjust pin current (typically
50 A) also flows through R2 and adds a small error that
should be taken into account if precise adjustment of V
OUT
is necessary.
The output voltage is set according to the formula:
