描述 Description

AW3703D280 is a low dropout voltage regulator featuring low ON resistance, high PSRR, low Noise, good load/line transient response and smooth softstart.
AW3703D280 integrates current limit, short circuit protection, thermal shutdown, sufficiently protecting IC from being damaged.
AW3703D280 is designed to work with a 1μF or more input ceramic capacitor and a 1μF or more output ceramic capacitor. The low power dissipation and good dynamic response make AW3703D280 very suitable for hand-held communication equipment. Tiny package makes high density mounting of the IC on boards possible.
