GENERAL DESCRIPTION
The SP6203 and SP6205 are ultra low noise
CMOS LDOs with very low dropout and ground
current.
The noise performance is achieved by
means of an external bypass capacitor without
sacrificing turn-on and turn-off speed critical
to portable applications.
Extremely stable and
easy to use, these devices offer excellent
PSRR and Line/Load regulation.
Target
applications
include
battery-powered
equipment such as portable and wireless
products.
Regulators' ground current increases
only slightly in dropout.
Fast turn-on/turn-off
enable control and an internal 30Ω pull down
