Linear Technology Corp. has developed the LT3023 low dropout and low noise micropower regulator.

Operating from an input voltage range of 1.8V to 20V, the product delivers two 100mA outputs at voltages as low as 1.22V. Its wide 1.8V to 20V input voltage accommodates sources from single cell Li-ion or multi-cell alkaline/NiMH, as well as higher voltage fixed rails.

With a 0.01?F bypass capacitor, output noise drops to 20?Vrms over a 10Hz to 100kHz bandwidth. It features a quiescent current per channel of 20?A, quiescent current in shutdown of <1?A per channel, and dropout voltage of 300mV at 100mA.

The LT3023 is available with an adjustable output in either a thermally enhanced MSOP-10 package or a 3-by-3mm DFN. Pricing starts at $1.70 (DFN) and $1.60 (MSOP) in 1,000-piece quantities.
