The CXLD64360 series is a low-dropout linear regulator. This device is designed specifically for battery-operated systems. Its ground current is very small - 50uA (typ.) that significantly extends the battery life. The low power consumption and high accuracy are achieved through CMOS and programmable fuse technologies. Its versions are CXLD64360-adj (Vref=1.27V), CXLD64360-1.2,CXLD64360-1.8, CXLD64360-2.5, CXLD64360-2.6, CXLD64360-3.3. It is possible to extend the output voltage range from 1.2V to 6.0V. The CXLD64360 consists of a high-precision voltage reference, an error-correction circuit, and a current-limited output driver. With good transient responses the device output remains stable even when the load changes. The EN (Shutdown) input enables the output to be turned off resulting in reduced power consumption. The CXLD64360 can stably work with cheap MLCC output capacitors. Owing to high ripple rejection ratios, the CXLD64360 series can be used in the case of a power supply with noise. A 470pF capacitor from the BP (bypass) input to the ground reduces the noise, which is present on the internal reference, and that, in turn, significantly reduces the output noise. If that noise is not a concern, the said input may be left unconnected. Larger CBP capacitor values may be used, but that extends a time period until the rated output voltage is reached after the power has been initially applied. The CXLD64360 incorporates both over-temperature and over-current protections. The small packages - SOT23-5 (300mW) and SOT-89 (500mW) - are usable too.
