    CXLD64213系列是实现了高精度,低噪声,高纹波抑制,低压差CMOS工艺的双路LDO电压调整器芯片。内部由基准电压源,误差放大器,驱动用晶体管,控制电流电路,相位补偿电路等构成。各个电压调整器的输出电压可由激光微调技术在内部0.8～5.0V的范围内，间隔0.05V进行调整。可由EN端子停止各个电压调整器的输出状态，使其成待机状态。此外，CXLD64213系列在带机状态时，VOUT端子和VSS端子之间的内部开关可把用于稳定输出的电容(CL)中储存的电荷放电。这个放电功能可使VOUT端子高速地返回VSS电平。用于稳定输出的电容(CL)也能与陶瓷电容等ESR低的电容相对应。此外，良好的过渡响应能使负载变动时得到稳定的输出。各个电压调整器实现了完全隔离，可以把由于输出负载变动等引起的各个电压调整器之间的串话抑制在极小的程度内。The CXLD64213 series is a dual CMOS LDO regulator. The series features high accuracy, low output noise, high ripple rejection and low dropout and consists of a voltage reference, error amplifier, driver transistor, current limiter, thermal shutdown circuit and phase compensation circuit. Each output voltage is set independently by laser trimming and selectable in 0.05V increments within a range of 0.8 to 5.0V. The EN function turns each output of the two regulators off independently. In this state, the electric charge at the output capacitor (CL) is discharged via the internal auto-discharge switch, and as a result the VOUT voltage quickly returns to the VSS level. The output stabilization capacitor (CL) is also compatible with low ESR ceramic capacitors. The high level of output stability is maintained even during frequent load fluctuations, due to the excellent transient response performance. VR1 and VR2 are completely isolated so that a cross talk during load fluctuations is minimized.fx3嘉泰姆
