Linear Technology LTC1798 Series Datasheet
The LTC1798 series from Linear Technology provides micropower bandgap references with low dropout (200 mV max at 10 mA) and ultra‑low quiescent current (4 µA typical). Available in 2.5 V, 3 V, 4.096 V, 5 V and adjustable versions, the devices can source up to 10 mA and sink 2 mA, making them suitable for battery‑powered instruments and precision regulators.
The datasheet includes electrical characteristics, absolute maximum ratings, pin functions, package information, and typical performance graphs. It also offers application guidance such as using output bypass capacitors up to 1 µF and the benefits of the internal P‑channel MOSFET pass transistor for low dropout operation.
