ST offers one of the widest selection of fixed and adjustable linear voltage regulators. Beside a complete portfolio of Industry Standard regulators for both Positive and Negative output, we offer an ever-expanding range of High performance regulators addressing all the major trends in the industry. Among our products, you can find the optimal combination of low dropout voltage and quiescent current - for the highest efficiency design - or dynamic performances for the best transient response, ripple rejection and low noise. All this coupled with a choice of the smallest form factor packages for size conscious applications. 

New 200 mA and 1.2A LDOs support up to 18 V input voltage

The LDK320 and LDL212 complete ST’s family of cost-effective LDOs, offering an optimal combination of low dropout voltage, low quiescent current and remarkable dynamic performance at a favorable price.

Thanks to the wide input voltage operating range, as high as 18 V, they can be used as post-regulators in  consumer applications (TVs, STBs), home appliances and industrial control modules, or directly attached to medium voltage battery packs in laptops and other battery-operated equipment. The LDK320 is also available in a 0.5% high accuracy version.

Both products are available in tiny packages allowing designers to save PCB space and build smaller systems.
