PRODUCTION DATA.
The TPS650861 device integrates three general purpose LDOs. LDOA1 is powered from a 5-V supply through the DRV5V_2_A1 pin and it can be factory configured to be an Always-On rail (stay on even in case of emergency shutdown) as long as a valid power supply is available at VSYS. See Table 5-4 for LDOA1 output voltage options. LDOA2 and LDOA3 share a power input pin (PVINLDOA2_A3). The output regulation voltages are set by writing to LDOAx_VID[3:0] bits (Reg 0x9A, 0x9B, and 0xAE). See Table 5-5 for LDOA2 and LDOA3 output voltage options. LDOA1 is controlled by the LDOA1_SWB2_CTRL register.
