一,产品概述(General Description) start up by supply voltage as low as 0.8V, and capable of delivering maximum 200mA output current at 3.3V output with 1.8V input Voltage. Quiescent current drawn from power source is as low as 5.5uA. All of these features make CXSU6337 series be suitable for the portable devices, which are supplied by a single battery to four-cell batteries.To reduce the noise caused by the switch regulator, CXSU6337 is well considerate in circuit design and manufacture, so that the interferer toother circuits by the device is reduced greatly. CXSU6337 integrates stable reference circuits and trimming technology, so it can afford high precision and low temperature-drift coefficient of the output voltage. CXSU6337 is available in SOT-89-3, SOT-23-3, SOT-23-5 and TO-92 packages, which is PB free. And in 5-pin packages, such as SOT-23-5, the device can be switch on or off easily by CE pin, to minimize the standby supply current. 二.产品特点(Features) Deliver 200mA at 3.3V Output voltage with 1.8V input Voltage Low start-up voltage (when the output current is 1mA)-------------0.8V Output voltage can be adjusted from 2.5V～6.0V (In 0.1V step) Output voltage accuracy ---------------±2％ Low temperature-drift coefficient of the output voltage-------±100ppm/℃ Only three external components are necessary: An inductor, a Schottky diode and an output filter capacitor High power conversion efficiency-----85％ Low quiescent current drawn from power source--------------------<5.5uA 三,应用范围 (Applications) Power Source for PDA, DSC, MP3 Player, Electronic toy and wireless mouse Power Source for a Single or Dual-cell Battery-Powered Equipments Power Source for LED 四.技术规格书下载（产品PDF） 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持！ 五,产品封装图 (Package) 六.电路原理图 七,功能概述
