Description

The CAT6241 is a low dropout CMOS voltage regulator providing up to 1000 mA of output current with fast response to load current and line voltage changes. CAT6241 offers a user adjustable output voltage from 0.5 V to 5.0 V and its low quiescent current make CAT6241 ideal for energy conscious designs. CAT6241 is available in space saving 2 mm x 2 mm UDFN−8 and 3 mm x 3 mm WDFN−6 packages, each with a power pad for heat sinking to the PCB.

CAT6241属于集成电路（IC） > 线性 + 开关稳压器。安森美半导体公司制造生产的CAT6241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。
