目录7.相关产品 产品概述 返回TOP CXLD64179系列是采用CMOS工艺,低消耗电流(1.0μA(TYP))的超小型正电压调整器芯片。该芯片在负载100mA的情况下输入输出电压差只有200mV,实现了低导通阻抗。封装采用超小型的USP-3和SSOT-24,是需求高密度的设备如手机等最适宜的产品。输出电压通过使用内部激光微调,可以实现0.9V~4.0V间0.1V间隔的输出。使用低ESR的陶瓷电容,便可得到稳定的输出。电流限制采用Foldback电路,可为输出提供限流短路保护.CXLD64179 series are highly precise, low noise, positive voltage LDO regulators manufactured using CMOS processes. The series achieves very low supply current, 1.0μA (TYP.) and consists of a reference voltage source, an error amplifier, current limit circuit, and a phase compensation circuit plus a driver transistor. Ultra small USP-3 and SSOT-24 packages make high density mounting possible. Therefore, the series is ideal for applications where high density mounting is required such as in mobile phones. Output voltage is selectable in 0.1V increments within a range of 0.9V~4.0V by laser trimming. The series is also compatible with low ESR ceramic capacitors (CL), which give added output stability. The current limiter’s fold-back circuit also operates as a short protect for the output current limiter and the output pin. 产品特点 返回TOP
