AW37030YXXX is a low dropout voltage regulator featuring low ON resistance, high PSRR, low Noise, good load/line transient response ａｎｄ smooth softstart. AW37030YXXX integrates current limit, short circuit protection, thermal shutdown, sufficiently protecting IC from being damaged. AW37030YXXX is designed to work with a 1uF ｏｒ more input ceramic capacitor ａｎｄ a 1uF ｏｒ more output ceramic capacitor. The low power dissipation ａｎｄ good dynamic response make AW37030YXXX very suitable for hand-held communication equipment. Tiny package makes high density mounting of the IC on boards possible.
