STが提供する固定出力および可変出力の リニア・ボルテージ・レギュレータの製品ラインは業界トップクラスの多様性を備えています。正負両出力の産業用 標準レギュレータを提供する総合ポートフォリオに加え、業界の主要なトレンドを漏れなく押さえるために、高性能 レギュレータの製品を継続的に拡充中です。STの広範な製品群を探せば、低ドロップ電圧と暗電流の最適の組合せを見つけることができます。これにより、高効率な設計、つまり、過渡応答、リップル除去、ノイズ低減に関して最高レベルの動特性が得られます。また、これらの利点と最小サイズのフォーム・ファクタ・パッケージの選択肢の組合せにより、サイズ重視のアプリケーションに最適です。 


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.

STLQ015 ultra-low quiescent current linear regulators

The STLQ015 ultra-low consumption LDOs provide up to 150 mA current from an input voltage ranging from 1.5 to 5.5 V. They feature a quiescent current of just 1.4 μA at the maximum load and a standby current of typically 1 nA, extending the battery lifetime in those applications requiring very long standby time. Requiring only two small external capacitors, they provide a cost-effective and space-saving solution for powering microcontrollers in portable and battery-powered systems, electronic sensors, home medical instruments and portable entertainment gadgets. The STLQ015 LDOs are available in a wide range of output voltages, from 0.8 V to 3.3 V in 100 mV steps.
