8 Detailed Description - Power Management Functions
8.1 Low Drop Out Regulators
These LDOs are designed to supply sensitive analog circuits, audio devices, AD and DA converters, micro-controller and other peripheral
devices. The design is optimized to deliver the best compromise between quiescent current and regulator performance for battery powered
devices.
Stability is guaranteed with ceramic output capacitors of 1μF ±20% (X5R) or 2.2μF +100/-50% (Z5U). The low ESR of these caps ensures low
output impedance at high frequencies. Regulation performance is excellent even under low dropout conditions, when the power transistor has to
operate in linear mode. Power supply rejection is high enough to suppress high ripple on the battery at the output. The low noise performance
allows direct connection of noise sensitive circuits without additional filtering networks. The low impedance of the power device enables the
device to deliver up to 150mA even at nearly discharged batteries without any decrease of performance.

8.1.1
LDO5
This LDO generates the digital supply voltage used for the PMU itself.
Input Voltage is VSUP5
Output Voltage is VDD27 (typ. 2.7V), this LDO always starts at the beginning of the start-up sequence as it is needed for all further
operation. The default voltage cannot be changed in the boot ROM.
Driver strength: 100mA, can be programmed to 200mA
It is set to a default output voltage of 2.7V, 100mA max . It supplies the analog and digital part of the PMU. Additional external loads are possible
but must not exceed the supply ratings in total together with the operating internal blocks. Further, the external load must not induce noise to the
VDD27.
