ST is a large supplier of industry standard linear voltage regulators and voltage references (the well known L7800, LM317, LD1117, TL431, etc.) with large in-house manufacturing capacity, high quality level (0.1 ppm failure rate on over 1 Bpcs shipped per year), and recognized cost competitiveness. ST is less widely known as a premier supplier of high performance LDOs. The chart on this slide shows LDOs in tiny packages vs. quiescent current (X-axis) and output current capability (different color). The flip-chip, 0.7 x 0.7 mm, is one of the smallest LDOs on the market. LDCL015 is a capacitor-less LDO, which is stable without input and output capacitors and does not compromise the supply voltage rejection performance. An optimized low-noise LDO design, like LDLN015, delivers an impressive low 6.3 mVRMS output noise voltage from 10 Hz to 100 kHz. Finally, the STLQ015 achieves a 1 µA quiescent current, to prolong battery life in applications with very long standby time, maintaining a fast load transient response at the same time.
