The S-1170 Series is a positive voltage regulator with a low dropout voltage (LDO), high output voltage accuracy, and low current
consumption developed based on CMOS technology.
A built-in low on-resistance transistor provides a low dropout voltage and large output current, a built-in overcurrent protector
prevents the load current from exceeding the current capacitance of the output transistor, and a built-in thermal shutdown circuit
prevents damage caused by the heat. An ON/OFF circuit ensures a long battery life. Compared with the voltage regulators using the
conventional CMOS process, a larger variety of capacitors are available, including small ceramic capacitors. Small SOT-89-5 and
6-Pin HSON(A) packages realize high-density mounting.
Features
• Output voltage: 1.5 V to 5.5 V, selectable in 0.1 V steps.
• High-accuracy output voltage: ±1.0%.
• Low dropout voltage (LDO): 120 mV typ. (3.0 V output product, Iout =300 mA).
• Low current consumption: During operation 80 μA typ. 160 μA max., During shutdown 0.1 μA typ. 1.0 μA max.
• High peak current capability: 800 mA output is possible (@ Vin >Vout(S) +1.0 V) *1
• Built-in ON/OFF circuit: Ensures long battery life.
• Low ESR capacitor can be used: A ceramic capacitor of 4.7 μF or more can be used for the output capacitor.
• High ripple rejection: 70 dB typ. (@ 1.0 kHz)
• Built-in overcurrent protector: Overcurrent of output
transistor can be restricted.
• Built-in thermal shutdown circuit: Damage caused by
heat can be prevented.
• Package: SOT-89-5, 6-pin HSON(A).
• IC9553: 2Mbit SPI-FLASH Memory
