Linear Technology Corp. (LTC, Milpitas, CA), a manufacturer of high-performance integrated circuits, announced the LT3024, a dual, low-noise, low-dropout (LDO), micropower regulator with both 500 mA and 100 mA outputs. It operates from an input-voltage range of 1.8 V to 20 V, delivering dual outputs at voltages as low as 1.22 V. Its wide input-voltage range accommodates sources from single-cell, lithium-ion or multi-cell alkaline/nickel-metal hydride, to higher-voltage fixed rails.
With a 0.01 µF bypass capacitor, output noise is a low 20 µVRMS over a 10 Hz to 100 kHz bandwidth. Designed for use in battery-powered systems, the low 30 µA quiescent current per channel makes it suitable for maximizing battery run time. Dropout voltage is only 300 mV (at 100 mA and 500 mA, respectively), enabling low-dropout applications such as 3.6 V input to a regulated 3.3 V output.
The LT3024 regulator is stable with 1 µF (100 mA output), 3.3 µF (500 mA output) output capacitors without any series resistance. Internal protection circuitry includes reverse battery protection, current limiting, thermal limiting and reverse current protection. The LT3024 is available with adjustable outputs in either a thermally enhanced TSSOP-16E package, or a 12-lead 4 mm x 3 mm DFN.
Both package options are available from stock, and 1,000-piece pricing starts at $2.45 each.
