TEXAS INSTRUMENTS TL103W TL103WA handbook
Datasheet
The TL103W and TL103WA combine the building blocks of a dual operational amplifier and a fixed voltage reference – both of which often are used in the control circuitry of both switch-mode and linear power supplies. The operational amplifier features low offset voltage, low supply current, unity gain bandwidth, etc. The voltage reference features a fixed 2.5V reference voltage, low temperature drift, wide output current range, etc.
