AW37103YXXX is a low quiescent current low dropout voltage regulator featuring low ON resistance, high PSRR, low Noise, good load/line transient response and smooth soft-start. AW37103YXXX integrates current limit, short circuit protection, thermal shutdown, sufficiently protecting IC from being damaged. AW37103YXXX is designed to work with a 1uF or more input ceramic capacitor and a 1uF or more output ceramic capacitor. The low quiescent current make AW37103YXXX very suitable for battery application with long service life. Tiny package makes high density mounting of the IC on boards possible.
