LDO2 can be controlled by hardware using the VSELECT and LDO2EN pins. When

controlling the LDO2 by hardware, the output voltage can be selectable by the VSELECT

pin as well as enabled/disabled by the LDO2EN pin.

15.5.1 LDO load switch operation

When the LDOxLS bit is set to 1, the corresponding LDO operates as a load switch,

allowing a pass-through from the LDOxVIN to the corresponding LDOxVOUT output

through a maximum 130 mΩ resistance. In this mode of operation, the input must be kept

inside the LDO operating input voltage range (2.5 V to 5.5 V)

The LDOxEN bit is used to enable or disable the switch.

15.5.2 LDO regulator electrical characteristics

Table 61. LDO regulator electrical characteristics

All parameters are specified at TA = −40 °C to 125 °C for AEC-Q100 grade 1 device, all parameters are specified at TA =

−40 °C to 105 °C for AEC-Q100 grade 2 device, VLDOxIN = 2.5 V to 5.5 V, VLDOx = 1.8 V, ILDOx = 100 mA, typical external

component values, unless otherwise noted. Typical values are characterized at VLDOxIN = 5.5 V, VLDOx = 1.8 V, ILDOx = 100

mA, and TA = 25 °C, unless otherwise noted.
