SPX3819 500mA Low-Noise LDO Voltage Regulator
Applications requiring a slow rampup of the The SPX3819 in Figure 19 illustrates a typical output voltage should use a larger CBYP. adjustable output voltage configuration. Two However, if a rapid turn-on is necessary, the resistors (R1 and R2) set the output voltage. BYP capacitor can be omitted. The output voltage is calculated using the The SPX3819’s internal reference is available formula: through the BYP pin. VOUT = 1.235V x [1 + R1/R2] Figure 18 represents a SPX3819 standard R2 must be >10kΩ and for best results, R2 application circuit. The EN (enable) pin is pulled should be between 22kΩ and 47kΩ. high (>2.0V) to enable the regulator. To disable the regulator, EN < 0.4V.
