PRODUCTION DATA
The internal LDO (INT LDO) regulator powers the TPS8804 amplifiers and digital core with a stable 2.3 V supply. Connect a 1-μF capacitor to VINT to stabilize the output. The INT LDO is always enabled when the device is powered. The INT LDO can be used to supply external circuitry. It is not recommended to power noisy or switching loads with INT LDO, as any noise on VINT couples to the internal amplifiers and can generate noise. The INT LDO can be used in the CO connectivity test circuitry and the photo reference circuitry.
