1 A voltage regulators

12 May 2010 Power Electronics / Power Management

ON Semiconductor has introduced five new CMOS linear voltage regulator families. The NCP69x families are optimised for use in low current consumption portable battery-powered and ‘always on’ applications such as cable modems, satellite receivers, digital-set-top boxes and electricity meters. The NCP690, NCP691 and NCP692 are very low dropout devices with an adjustable output voltage from 5,0 V down to 1,25 V or in fixed voltage versions. The NCP693 operates with a supply current of only 65 μA at no load, and a standby mode with a supply current less than 0,15 μA, selected by a chip enable pin. Standard voltage versions are 0,8 V, 1,0 V, 1,2 V, 2,5 V and 3,3 V. This series is complemented by the NCP694, which is an ultra low dropout variant for applications where there is a small differential between the input and output voltage.
