Detailed Functional Description
7.1
Analog LDO
The LDO is a general purpose LDO and the output pin is shared with the current source (sink) connected to
RGB3. 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 (see Figure 3) of 1µF ±20% (X5R) or 2.2µF +100/-50%
(Z5U). The low ESR of these capacitors ensures low output impedance at high frequencies. The low impedance
of the power transistor enables the device to deliver up to 150mA even at nearly discharged batteries without any
decrease in performance.
The LDO is off by default after startup (apply voltage on VDD_GPIO)
