the fp6186a is a family of cmos low dropout (ldo) regulators with a low dropout voltage of 400mv at 600ma designed for noise-sensitive portable device, rf and wireless applications. quiescent current of fp6186a is as low as 60μa 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 fp6186a is available in a sot-23-5 package.
