1_00 ULTRA LOW CURRENT CONSUMPTION AND LOW DROPOUT CMOS VOLTAGE REGULATOR S-1206 Series The 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.
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 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.
