Power management
Voltage regulators
The power management block on the device avoids the requirement for any external system
regulators in a 5 V based camera product. The scheme is shown in
Digital Regulator 1 - This 5 V to 3.3 V regulator uses an external bipolar transistor to supply
loads up to 200 mA. It is typically used to power the sensor digital logic and may also be used
to supply an external co-processor if required. This regulator is always on.
Digital Regulator2 - This 3.3 V to 1.8 V regulator uses an external bipolar transistor to supply
loads up to 100 mA. This supply may be used for an external co-processor if required. This
regulator is controlled by the PDREG1V8 pin and must be switched off if not required.
Audio Amp Regulator - This 5 V to 3.3 V regulator supplies the audio amplifier and the buffer
amplifier used to supply the reference to the microphone (Load 5 mA). It should be externally
decoupled with a 2.2 µF capacitor. For applications without audio this regulator may be
powered down via the SIF registers.
Video Regulator - This 5 V to 3.3 V regulator supplies the analogue video circuitry. It should be
externally decoupled with a 2.2 µF capacitor.
