HIGH RIPPLE-REJECTION LOW DROPOUT HIGH OUTPUT CURRENT
CMOS VOLTAGE REGULATOR
S-1172 Series
The S-1172 Series, developed based on CMOS technology, is a positive
voltage regulator with a super low dropout voltage, high output voltage
accuracy, and low current consumption.
The S-1172 Series provides the very small dropout voltage and the large
output current due to the built-in transistor with low on-resistance. The
overcurrent protector prevents the load current from exceeding the
capacitance of output transistor. The thermal shutdown circuit prevents
damage caused by heat, the rush current control circuit limits the
excessive rush current during start-up.
The ON/OFF circuit ensures longer battery life. Various capacitors, also
small ceramic capacitors, can be used for this IC more than for the
conventional regulator ICs which have CMOS technology.
The packages, high heat radiation HSOP-6 and small SOT-89-5 enable
high-density mounting.
