8.1.1

LDO Registers

1. Not production tested – guaranteed by design and laboratory verification

2. During startup of the LDO the current limit is half the value of ILIMIT

Table 6. Reg. control

Addr: 00

Reg. control

This register enables/disables the LDOs, Charge Pumps, Charge Pump LEDs,

current sinks, the Step Up DC/DC Converter, and low-power mode.

Analog LDO is switched off

Analog LDO is switched on

ldo_ana_lpo

0R/W

Normal Operation

Low-power mode; 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.
