SPX3819 Summary of contents
Page 1
... The SPX3819 is a positive voltage regulator with a low dropout voltage and low noise output. In addition, this device offers a very low ground current of 800µA at 100mA output. The SPX3819 has an initial tolerance of less than 1% max and a logic compatible ON/OFF switched input. When disabled power consumption drop to nearly zero ...

... The SPX3819’s internal reference is available through the BYP pin. Figure 1 represents a SPX3819 standard appli- cation circuit. The EN (enable) pin is pulled high (>2.0V) to enable the regulator. To disable the regulator, EN < 0.4V. The SPX3819 in Figure 2 illustrates a typical adjustable output voltage configuration. Two resistors (R output voltage is calculated using the formula must be > ...
