CM2830/CM2830A

300mA CMOS LDO

GENERAL DESCRIPTION

The CM2830/CM2830A family is a positive voltage linear

regulator developed utilizing CMOS technology featured low

quiescent current (30

A typ.), low dropout voltage, and high

output voltage accuracy. Built-in low on-resistance transistor

provides low dropout voltage and large output current. A

2.2

F or greater can be used as an output capacitor.

The SOT-23-3, SOT-23-5, and TO-92 miniaturized package

and the SOT-89 package are recommended for configuring

portable devices and large current application, respectively.

These robust devices are designed to prevent device failure

under the worst operation condition with both Thermal

Shutdown and Current Fold-back.

大功率开关电源中功率MOSFET的驱动技术: 功率MOSFET具有导通电阻低、负载电流大的优点，因而非常适合用作开关电源（switch-modepowersupplies，SMPS）的整流组件，不过，在选用MOSFET时有一些注意事项。功率MOSFET和双极型晶体管不同，它的栅极电容比较大，在导通之前要先对该电容充电，当电容电压超过阈值电压（VGS-TH）时MOSFET才开始导通。因此，栅极驱动器的负载能力必须足够大，以保证在系统要求的时间内完成对等效栅极电容（CEI）的充电。在计算栅极驱动电流时，最常犯的一个错误就是将MO...; wzt 电源技术
