ME6217 Series High Output Current LDO Regulator , High PSRR , Low Dropout
General Debion
The ME6217 Series is a positive voltage regulator with a low dropout voltage,high output voltage accuracy,and low crrent consumption developed based on CMOS technology.
A built-in low on-resistance transistor provides a low dropout voltage and large output current, a built-in overcurrent protector prevents the load current from exceeding the current capacitance of the output transistor. An ON/OFF circuit ensures a long battery life. Compared with the voltage regulators using the conventional CMOS process, a larger variety of capacitors are available, including small ceramic capacitors.
