GENERAL DESCRIPTION
An internal 0.8V reference allows the output voltage to be precisely regulated to meet low output voltage requirement. A fixed 300kHz oscillation frequency reduces the component size for saving board area. The RT9203/A also features over voltage protection (OVP) and under voltage lock-out (UVLO).FEATURES
