Product details
Overview
The ST8207 series are positive voltage regulators with low dropout voltage, high output voltage accuracy and low current consumption, developed based on CMOS technology. A built-in low on-resistance transistor provides a low dropout voltage of just 100mV at 300mA load (VOUT=5V) and a large 800mA output current; a built-in overcurrent protector prevents the load current from exceeding the current capacity of the output transistor, and an ON/OFF circuit ensures a long battery life. Compared with regulators using conventional CMOS processes, a larger variety of capacitors are available, including small ceramic capacitors.
