Positive Voltage Regulator
Seiko's S-1206 series is a positive voltage regulator with ultra-low current consumption, low dropout voltage, high output voltage accuracy and 250 mA output current developed based on CMOS technology. I/O capacitors are as small as 0.1 µF. The S-1206 series operates at an ultra-low current consumption of 1.0 µs (typ.). The built-in low-on-resistance transistor realizes low dropout voltage and high output current. A built-in overcurrent protection circuit prevents the load current from exceeding the current capacitance of the output transistor. Three packages, SOT-23-3, SOT-89-3 and SNT-6A(H), are available. Compared with voltage regulators using a conventional CMOS process, more types of capacitors, including small I/O capacitors, can be used with the S-1206 series, according to the company.
