The SPX3819’s internal reference is available
through the BYP pin.
Figure 18 represents a SPX3819 standard
application circuit. The EN (enable) pin is
pulled high (>2.0V) to enable the regulator.
To disable the regulator, EN < 0.4V.
Fig. 18: Standard Application Circuit
The SPX3819 in Figure 19 illustrates a typical
adjustable output voltage configuration. Two
resistors (R1 and R2) set the output voltage.
The output voltage is calculated using the
formula:
VOUT = 1.235V x [1 + R1/R2]
R2 must be >10kΩ and for best results, R2
should be between 22kΩ and 47kΩ.
