Table 142. LDO1 output voltage selection bits...continued

The LDO1 features a programmable soft-start time to set a fixed ramp-up time, regardless of the output voltage

level. The ramp-up time is selected in OTP via the OTP_LDO1_SS bit.

Table 144. LDO1 load switch selection mode

In load switch mode, the block is capable of taking an input as low as 1.8 V and enabling the output in the

Power-up sequence, or enabling the output manually via the LDO1_RUN_EN and LDO1_STBY_EN bits.

When the LDO1 is operating in load switch mode, the monitoring voltage level is set by the VLDO1_RUN[4:0]

and the VLDO1_STBY[4:0] bits in the RUN and Monitored STANDBY states respectively. It is responsibility

of the system designer to set the voltage monitoring setpoint and the OV/UV monitoring threshold to a proper

level, to account for DC losses in the pass FET.
