Figure 6. Variable Slew Rate Filter
LOW OVERHEAD VOLTAGE REFERENCE
Figure 7 shows a voltage reference that requires only 0.1 V of
overhead voltage. As shown, the reference provides a stable
4.5 V output with a 4.6 V to 36 V supply. Output voltage drift is
only 12 ppm/
°
C. Line regulation of the reference is under 5 HV/V
with load regulation better than 10
μ
V/mA with up to 50 mA of
output current.
The REF-43 provides a stable 2.5 V which is multiplied by the
OP290. The PNP output transistor enables the output voltage
to approach the supply voltage.
Resistors R1 and R2 determine the output voltage.

The 200
variable resistor is used to trim the output voltage.
For the lowest temperature drift, parallel resistors can be used in
place of the variable resistor and taken out of the circuit as required
to adjust the output voltage.
