S-1206B33-M3T1U

The S-1206 Series is a positive-voltage regulator developed using CMOS technology, featuring ultra-low quiescent current, low dropout voltage, high-accuracy output voltage, and 250 mA output current. It requires minimal input/output capacitors of only 0.1 μF and operates under ultra-low quiescent current conditions (1.0 μA typ.). In addition, the built-in low on-resistance transistor enables a small input/output voltage differential and high output current. An overcurrent protection circuit is integrated to prevent the load current from exceeding the current capacity of the output transistor. Compared to conventional CMOS-process voltage regulators, this product supports a wider variety of capacitors, including small ceramic capacitors for both input and output. The combination of ultra-low quiescent current and compact packaging makes it ideal for portable devices.
