ULTRA LOW CURRENT CONSUMPTION AND
LOW DROPOUT CMOS VOLTAGE REGULATOR
Rev.3.2
_00
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.
Three packages, SOT-23-3, SOT-89-3, and SNT-6A(H) are available.
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.
