ABLIC S-1206B28-U3T1G

The S-1206 Series is a positive voltage regulator with ultra low current consumption, low dropout voltage, high-accuracy output voltage, and 250 mA output current developed based on CMOS technology. I/O capacitors are as small as 0.1 μF. S-1206 Series operates at ultra low current consumption of 1.0 μA (typ.). The built-in low-on-resistance transistor realizes low dropout voltage and a large output current. A built-in overcurrent protection circuit prevents the load current from exceeding the current capacity of the output transistor. Compared with voltage regulators using a conventional CMOS technology, more types of capacitors, including small I/O capacitors, can be used with the S-1206 Series. The S-1206 Series features ultra low current consumption and comes in a small package, making them most suitable for portable equipment.
