AMG-PU005
Analog System Base Chip, I/O PowerStage, OP-Amps
5.8. 5V Linear Regulator
The 5V Linear Regulator is a shunt regulator which can be used to generate about 5V from
voltages up to 36V. It is over-current and short circuit protected.
5.9. Open Drain Drivers
The AMG-PU005 has got a N-Channel and P-Channel Driver with 100mA output current
driving capability each. Both Drivers are built in Open Drain configuration. The drivers are
over-current and over-temperature protected.
5.10. LED Current-Sink Blocks
The current sink blocks are dedicated to drive LEDs from a supply voltage (5-36V) with a
current of 2mA each.
5.11. OP-Amp Blocks
The general purpose OP-Amp blocks allow the customer to built own I/O interfaces. The OP-
Amps provide a rail-to-rail input and output.
