RT9166是一款高精度,低功耗,3引脚LDO高电压调整器芯片,并采用 CMOS工艺和激光微调技术. 在输出电流较大的情况下,输入输出压差也能很小。RT9166芯片内部包括一个电流限制电路,一个驱动三极管,一个高精度参考电压源和一个误差校正电路。RT9166可使用低ESR陶瓷电容.电流限制器的foldback电路可为电流限制器和输出引脚提供短路保护。通过激光微调技术,可设定芯片的输出电压,其范围是1.2V至5.0V,间隔为100mV。
The RT9166/A series are CMOS low dropout regulators optimized for ultra-fast transient response. The devices are capable of supplying 300mA or 600mA of output current with a dropout voltage of 230mV or 580mV respectively.
The RT9166/A series are is optimized for CD/DVD-ROM, CD/RW or wireless communication supply applications. The RT9166/A regulators are stable with output capacitors as low as 1μF. The other features include ultra low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio.
The devices are available in fixed output voltages range of 1.2V to 4.5V with 0.1V per step. The RT9166/A regulators are available in 3-lead SOT-23, SOT-89, SOT-223, TO-92 and TO-252 packages
