SOT-89-3 (UP003-A)
SOT-23-3 (MP003-C)
SNT-6A(H) (PI006-A)The S-1206 Series is a positive voltage regulator with ultra low current consumption, low dropout voltage (LDO), high output voltage accuracy, 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 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. The S-1206 Series features ultra-low current consumption and comes in a small package, making them most suitable for portable equipment.
