General Description
The AS9106 is a family of CMOS low dropout (LDO) regulators with a low dropout voltage of 240mV at 600mA designed for noise-sensitive portable device, RF and wireless applications. Quiescent current of AS9106 is as low as 45μA 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 protection and on-chip thermal shutdown function provide protection against any combination of over-load or ambient temperature which could cause junction temperature exceeding maximum rating.
The space-saving tiny SOT23-5L and DFN1010-4L packages are attractive for hand-held applications. The device is specified over an ambient temperature range of -40˚C to 125˚C.
