! c# F& U' U+ _* h4 O: d1 `The PS3120A is a low noise switched capacitor voltage doubler. It produces a regulated output voltage from a 2.7V to 4.5V input. Low external parts count (one flying capacitor and two small bypass capacitors at VIN and VOUT) make the PS3120A ideally suited for small, battery-powered applications. : o6 E% G. ?4 B. w5 Q# w

shutdown feature disconnects the load from VIN and reduces quiescent current to <1μA. : I2 [9 `+ z! S# P% D+ ^ h
The PS3120A is available in the industry standard SOT-23-6L power packages.$ y/ z( R' V! C
PS3120A是不需要电感的锂电池升压IC，输出电压4.94V，输出电流最大可以做到230MA。比较适合用在小功率的电子产品中。
