YP6821 is a low-dropout LDO with an output voltage range of 1.2-5V, an output current of 100mA, a low drop of 160mV and a power consumption of 2.0uA.
The YP6821 series is a CMOS‑based low‑dropout regulator offering a typical dropout of 160 mV at 3.0 V output and 50 mA load. It provides high precision (±2 % voltage accuracy) and a very low quiescent current of about 2 µA.
The device supports an input voltage range of 1.8 V to 6 V, delivers up to 100 mA output current, and is available in compact SOT‑23, SOT‑353 and SOT‑89‑3 packages with power dissipation limits of 250 mW (SOT‑23/353) or 500 mW (SOT‑89). Operating temperature spans from –25 °C to +85 °C (extended –40 °C to +125 °C). This manual is written in Chinese.
