6.3.1.7 LDO1

LDO1 is a general-purpose LDO intended to provide power to analog circuitry on the SOC. LDO1 has an input voltage range from 1.8 V to 5.5 V, and can be connected either directly to the system power or the output of a DCDC converter. The output voltage is programmable in the range of 0.9 V to 3.4 V with a default of 1.8 V. LDO1 supports up to 200 mA at the minimum specified headroom voltage, and up to 400 mA at the typical operating condition of VOUT = 1.8 V, VIN_LDO1 > 2.7 V.
