S-1112

S-1112/1122 Series www.sii-ic.com © Seiko Instruments Inc., 2002-2015 HIGH RIPPLE-REJECTION AND LOW DROPOUT CMOS VOLTAGE REGULATOR Rev.6.1_00 The S-1112/1122 Series is a positive voltage regulator with a low dropout voltage, high-accuracy output voltage, 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, and a built-in overcurrent protection circuit prevents the load current from exceeding the current capacity of the output transistor. An ON/OFF circuit ensures a long battery life. Compared with the voltage regulators using the conventional CMOS technology, a larger variety of capacitors are available, including small ceramic capacitors. Small SNT-6A(H) (S-1112 Series only) and SOT-23-5 packages realize high-density mounting. In SOT-23-5, the lineup includes the S-1112 and S-1122 Series, which differ in pin configuration.  Features Output voltage: Output voltage accuracy: Dropout voltage: Current consumption: Output current: Output capacitor: Ripple rejection: Built-in overcurrent protection circuit: Built-in ON/OFF circuit: Operation temperature range: Lead-free, Sn 100%, halogen-free*2 1.5 V to 5.5 V, selectable in 0.1 V step ±1.0% 190 mV typ.
