The ME6249A33M3G is a low-dropout (LDO) regulator in a SOT23-3 RoHS package, manufactured by Micro One. It features an ultra-low quiescent current of typically 3 µA, and a wide input voltage range of 2.75 V to 5.5 V. The output voltage is regulated to an accuracy of ±1%. It offers a low drop-out voltage of 160 mV at 1A load current, a high PSRR of 85 dB at 1 kHz, and fast transient response. Additionally, it has excellent output accuracy over temperature and load changes, and its enable pin facilitates power-saving applications. The device is optimized for use with ceramic dielectric capacitors – reducing the need for bulky external components for ripple suppression. It is protected from damage due to output over-voltage, current overload, thermal shutdown, and reverse current. The ME6249A33M3G is suitable for applications such as portable equipment, position-sensing devices, and hand-held instruments.
