AW37031YXXX is a low dropout voltage regulator featuring low ON resistance, high PSRR, low Noise, good load/line transient response and smooth soft-start.
AW37031YXXX integrates current limit, short circuit protection, thermal shutdown, sufficiently protecting IC from being damaged.
AW37031YXXX is designed to work with a 1uF in more input ceramic capacitor and a 1uF in more output ceramic capacitor. The low power dissipation and good dynamic response make AW37031YXXX very suitable for hand-held communication equipment. Tiny package makes high density mounting of the IC on boards possible.
