世纪芯较早就已经顺利取得技术突破,成功破解多款典型IC芯片,而由于解密难度大、周期长,使得解密成本及费用相对较高。为此,世纪芯又专门组织技术力量进行该系列芯片低成本解密方案研究,使针对SPX2810R-2.5芯片解密的技术更为成熟,解密成本更低,为客户实现更大经济效益。这里,我们仅以SPX2810R-2.5芯片为例,针对其性能特征做简单介绍:
The SPX2810 is a low power positive-voltage regulator designed to satisfy  moderate power requirements with a cost effective, small footprint solution. This device is an excellent choice for use in battery-powered applications and portable computers. The SPX2810 has a very low
quiescent current and a low dropout voltage of 1.1V at full load. As output current decreases,quiescent current flows into the load,increasing efficiency. SPX2810 is available in adjustable or fixed 2.5V, 3.0V and 3.3V output voltages.The SPX2810 is offered in several industry tandard 3-pin surface mount packages: SOT-223,TO-252, TO-220 and TO-263.  An output capacitor of 10?F or larger, provides unconditionally stability for most applications.
