PRODUCTION DATA.
Provides a 4-V reference voltage for use in conjunction with R3/R4 of the typical application circuit to set the voltage on the PROG pin. The reference voltage is available once the internal POR and UVLO thresholds have been met. It is not designed as a supply voltage for other circuitry, therefore ensure that no more than 1 mA is drawn. Bypass capacitance is not required, but if a special application requires one, less than 1000 pF can be placed on this pin.
