Notes:
1.
The Line Regulation in Table 3 is valid for whole output voltage (1.8 to 3.3V), if (VBAT-VANA1,2) >200mV.
2.
The static Load Regulation in Table 3 is valid for whole output voltage (1.8 to 3.3V) and current range (0
to 100mA), if (VBAT-VANA1,2) >200mV.
3.
The load condition for this value is a 1 to 100mA and 100 to 1mA steps.
4.
The static load regulation in Table 3 is valid for the whole output voltage range (1.8 to 3.3V) and current
range (0 to 5mA), if (VBAT-VANA1,2) >500mV.
5.
The load condition for this value is a 0.05 to 5mA and 5 to 0.05mA steps.
6.
The duration of operation in current limit is only dependent on the total power dissipation of the device.
If this limit exceeded, the overtemperature detection might disable the device temporarily.
7.
During startup of the LDO the current limit is half the value of ILIMIT
8.
Not production tested – guaranteed by design and laboratory verification
7.1.1 LDO Registers
Table
4 – Register definition for Analog LDO
Reg. Control
Addr: 00
This register enables/disables the LDOs, Charge Pumps, Charge Pump
LEDs, current sinks, the Step Up DC/DC Converter, and low-power mode.

0 = Normal Operation
1 = Low-power mode; (ldo_ana1 only),current
consumption is reduced by about 75µA. Reduced
performance of LDO: max 5mA load, internal oscillator is
switched off. The device will exit low-power mode
automatically, if blocks requiring the oscillator are
enabled.
