The Littelfuse TMOV
®
34S thermally protected varistor
series consists of a 34mm square format varistor element
(MOV) with an integral thermally activated element. This
element is designed to open in the event of overheating
due to abnormal overvoltage, limited current conditions.
Certain TMOV
®
34S varistor are offered with a "monitor"
lead which may be connected to signalling circuity to
indicate if the MOV has been disconnected from the circuit.
TMOV
®
34S varistor series offer quick thermal response due
to the close proximity of the integrated thermal element
to the MOV body. The integrated configuration also offers
lower inductance than most discrete solutions resulting
in improved clamping performance to fast over voltage
transients.

将25V左右的电压降至3.3V左右,低功耗要求,不能使用LM2596之类的吗
小白一枚,请教下大神们:我要将25V左右的电压降至3.3V左右给后端的MSP430和加速度传感器使用。要求低功耗(因为是利用的电磁振动发的电),有什么好的降压芯片推荐吗?是不是完全不能使用LM259 ......
