1 / 68 page  S-19244xxxH Series AUTOMOTIVE, 105°C OPERATION, 10 V INPUT, 1000 mA VOLTAGE REGULATOR WITH SOFT-START FUNCTION www.ablicinc.com © ABLIC Inc., 2016-2018 Rev.3.2_00 1 The S-19244xxxH Series developed by using high-withstand voltage CMOS process technology, is a positive voltage regulator with high-accuracy output voltage and high output current. 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. In addition to the type in which output voltage is set inside the IC, the type for which output voltage can be set via an external resistor is added to a lineup. Also, the S-19244xxxH Series includes the soft-start function to adjust the output voltage rising time at power-on or at the time when the ON / OFF pin is set to ON. Caution This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in the purpose, contact to ABLIC Inc. is indispensable. Features • Output voltage (internally set): 1.0 V to 6.0 V, selectable in 0.05 V step • Output voltage (externally set): 1.0 V to 9.0 V, settable via external resistor (HSOP-8A, HSOP-6 and HSNT-8(2030) only) • Input voltage: 2.5 V to 10.0 V • Output voltage accuracy: ±2.3% (Tj = −40°C to +105°C) • Dropout voltage: 0.38 V typ. (2.6 V output product, at IOUT = 1000 mA) • Current consumption: During operation: 120 μA typ., 150 μA max. (Tj = −40°C to +150°C) During power-off: 0.1 μA typ., 4.5 μA max. (Tj = −40°C to +105°C) • Output current: Possible to output 1000 mA (at VIN ≥ VOUT(S) + 1.0 V) *1 • Ripple rejection: 60 dB typ. (at f = 1.0 kHz) • Built-in overcurrent protection circuit: Limits overcurrent of output transistor. • Built-in thermal shutdown circuit: Detection temperature 170 °C typ. • Built-in soft-start circuit: Adjusts output voltage rising time at power-on or at the time when ON / OFF pin is set to ON. Adjustable type: E / F / G / H type, tSS = 6.0 ms typ. (CSS = 10 nF) Soft-start time can be changed by the capacitor (CSS). Fixed type: A / B / C / D type: Fixed to tSS = 1.0 ms typ. • Built-in ON / OFF circuit: Ensures long battery life Discharge shunt function "available" / "unavailable" is selectable. Pull-down function "available" / "unavailable" is selectable. • Operation temperature range: Ta = −40°C to +105°C • Lead-free (Sn 100%), halogen-free • 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. Applications • Constant-voltage power supply for electrical application for vehicle interior • Constant-voltage power supply for home electric appliance • For automotive use (car body, headlight, ITS, accessory, car navigation system, car audio system, etc.) Packages • TO-252-5S(A) • HSOP-8A • HSOP-6 • HSNT-8(2030) www.ablic.com |
