S-1206 Series ULTRA LOW CURRENT CONSUMPTION AND LOW DROPOUT CMOS VOLTAGE REGULATOR www.sii-ic.com SII Semiconductor Corporation, 2006-2015 Rev.3.2 01 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 F. S-1206 Series operates at ultra low current consumption of 1.0 A (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. Features Output voltage: 1.2 V to 5.2 V, selectable in 0.05 V step Input voltage: 1.7 V to 6.5 V Output voltage accuracy: 1.0% (1.2 V to 1.45 V output product: 15 mV) Dropout voltage: 150 mV typ. (3.0 V output product, IOUT = 100 mA) Current consumption: During operation: 1.0 A typ., 1.5 A max. *1 Output current: Possible to output 250 mA (3.0 V output product, VIN VOUT(S) + 1.0 V) Input and output capacitors: A ceramic capacitor of 0.1 F or more can be used. Built-in overcurrent protection circuit: Limits overcurrent of output transistor. Operation temperature range: Ta = 40C to +85C *2 Lead-free, Sn 100%, halogen-free *1. Attention should be paid to the power dissipation of the package when the output current is large. *2. Refer to Product Name Structure for details.
