TQL850CSV50集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TQL850CSV50属于集成电路（IC）的线性+开关稳压器。由台湾半导体股份有限公司制造生产的TQL850CSV50稳压器 - 线性线性稳压器用于提供稳定的输出电压，无论负载电流、输入电压或环境因素如何变化，这些输出电压通常都要保持不变。它们的工作原理要求输入电压维持在高于所需的输出电压，而且要超出某个最小量，并且在工作时会将输入端的任何多余电压转换为热量。对于大多数应用而言，虽然这种稳压器的效率低于开关模式的稳压器，但它们通常更适合对噪声高度敏感的应用。

DESCRIPTION

The TQL850CSV50 is a high-performance low dropout

linear regulator for 5V with input range of 3V to 50V and

low quiescent 40μA. TQL850CSV50 provides 2% output

voltage accuracy and 500mA maximum driving current

and is suitable for automotive or other supply systems.

TQL850CSV50 just requires one small ceramic

capacitor of 1μF to exhibit fast regulation and good

stability. And it shows very low dropout voltage with

typical 60mV in 100mA-load and 150mV in 250mA-load.

The start operating voltage is 3V which is suitable to

cranking condition of automotive system.

The device has an enable function to switch ON and

OFF for power dissipation. And other protection

functions such as thermal-shutdown and current-limit

are against immediate damage.
