FP6142数据手册Fitipower中文资料规格书

描述 Description

The FP6142 is a family of CMOS low dropout (LDO) regulators with a low dropout voltage of 250mV at 500mA designed for noise-sensitive portable device, RF and wireless applications. Quiescent current of FP6142 is as low as 50μA and it works with low-ESR ceramic capacitors, which makes it very suitable for space sensitive handheld applications. The soft-start function will eliminate current surges during start-up and the output discharge function will dissipate the residue output voltage in the capacitor during shut-down. Other features include current limit, thermal protection, high output accuracy, and low noise output etc.. The FP6142 is available in SC-70-5 package.
