Seiko's S-1170 Series LDO voltage regulator is a high output current (800 mA) capable CMOS based LDO. The CMOS process permits current consumption of 80 µA during operation and 0.1 µA during shutdown. An ON/OFF circuit further ensures battery longevity. Optimized for noise sensitive applications, this device has a 70 dB ripple rejection ratio that is achieved without the need of an external bypass capacitor. The SOT-89-5 and 6-pin HSON(A) package designs provide for high density mounting. The series has applications in an array of electronic equipment including PDAs, notebook PCs, handheld games, home security equipment, digital cameras, and portable audio devices. Other specifications include an output voltage range of 1.5 to 5.0 V in 0.1 V increments and an LDO voltage of 120 mV typical. The devices include a built-in thermal shutdown circuit.
