1 / 58 page  S-19212B/DxxA Series www.sii-ic.com FOR AUTOMOTIVE 125 °C OPERATION HIGH-WITHSTAND VOLTAGE LOW DROPOUT CMOS VOLTAGE REGULATOR © SII Semiconductor Corporation, 2015-2017 Rev.5.1_00 1 The S-19212B/DxxA Series, developed by using high-withstand voltage CMOS process technology, is a positive voltage regulator with a high-withstand voltage, low current consumption and high-accuracy output voltage, and has a built-in ON / OFF circuit. The S-19212B/DxxA Series operates at the maximum operation voltage of 36 V and a low current consumption of 6.5 μA typ., and has a built-in low on-resistance output transistor which provides a very small dropout voltage and a large output current. Also, a built-in overcurrent protection circuit to limit overcurrent of the output transistor and a built-in thermal shutdown circuit to limit heat are included. Caution This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in the purpose, contact to SII Semiconductor Corporation is indispensable. Features • Output voltage: 2.5 V to 16.0 V, selectable in 0.1 V step • Input voltage: 3.0 V to 36 V • Output voltage accuracy: ±2.0% (Tj = −40°C to +125°C) • Current consumption: During operation: 6.5 μA typ., 8.5 μA max. (Tj = −40°C to +125°C) During power-off: 0.1 μA typ., 3.5 μA max. (Tj = −40°C to +125°C) • Output current: Possible to output 250 mA (at VIN ≥ VOUT(S) + 2.0 V) *1 • Input capacitor: A ceramic capacitor can be used. (1.0 μF or more) • Output capacitor: A ceramic capacitor can be used. (1.0 μF to 100 μF) • Built-in overcurrent protection circuit: Limits overcurrent of output transistor. • Built-in thermal shutdown circuit: Detection temperature 165 °C typ. • Built-in ON / OFF circuit: Ensures long battery life. • Built-in discharge shunt circuit: Discharges the electric charge of the output capacitor during power-off. (RLOW = 70 k Ω typ.) • Operation temperature range: Ta = −40°C to +125°C • Lead-free (Sn 100%), halogen-free • Withstand 45 V load dump • AEC-Q100 qualified *2 *1. Please make sure that the loss of the IC will not exceed the power dissipation when the output current is large. *2. Contact our sales office for details.
