1 / 74 page S-13A1 Series www.sii-ic.com HIGH RIPPLE-REJECTION LOW DROPOUT HIGH OUTPUT CURRENT CMOS VOLTAGE REGULATOR © SII Semiconductor Corporation, 2011-2016 Rev.2.1_00 1 The S-13A1 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 2.2 μF small ceramic capacitor can be used, and the very small dropout voltage and the large output current due to the built-in transistor with low on-resistance are provided. The S-13A1 Series includes a load current protection circuit that prevents the output current from exceeding the current capacity of the output transistor and a thermal shutdown circuit that prevents damage due to overheating. In addition to the types in which output voltage is set inside the IC, a type for which output voltage can be set via an external resistor is added to a lineup. Also, the S-13A1 Series includes an inrush current limit circuit to limit the excess inrush current generated at power-on or at the time when the ON / OFF pin is set to ON. High heat radiation HSOP-8A and HSOP-6 or small SOT-89-5 and HSNT-6A packages realize high-density mounting. Features • Output voltage (internally set): 1.0 V to 3.5 V, selectable in 0.05 V step • Output voltage (externally set): 1.05 V to 5.0 V, settable via external resistor (HSOP-8A, HSOP-6 and SOT-89-5 only) • Input voltage: 1.5 V to 5.5 V • Output voltage accuracy: ±1.0% (internally set, 1.0 V to 1.45 V output product: ±15 mV) • Dropout voltage: 70 mV typ. (3.0 V output product, IOUT = 300 mA) • Current consumption: During operation: 60 μA typ., 90 μA max. During power-off: 0.1 μA typ., 1.0 μA max. • Output current: Possible to output 1000 mA (VIN ≥ VOUT(S) + 1.0 V) *1 • Input and output capacitors: A ceramic capacitor of 2.2 μF or more can be used. • Ripple rejection: 70 dB typ. (f = 1.0 kHz) • Built-in overcurrent protection circuit: Limits overcurrent of output transistor. • Built-in thermal shutdown circuit: Prevents damage caused by heat. • Built-in inrush current limit circuit: Limits excessive inrush current generated at power-on or at the time when the ON / OFF pin is set to ON. For types in which output voltage is internally set of HSOP-8A, HSOP-6 and SOT-89-5 inrush current limit time can be changed via an external capacitor (CSS). Inrush current limit time 0.7 ms typ. (types in which output voltage is internally set of HSOP-8A, HSOP-6 SOT-89-5, CSS = 1.0 nF) Inrush current limit time 0.4 ms typ. (types in which output voltage is internally set of HSOP-8A, HSOP-6, SOT-89-5, SSC pin = open) Inrush current limit time 0.4 ms typ. (types in which output voltage is externally set of HSOP-8A, HSOP-6, SOT-89-5, types in which output voltage is internally set of HSNT-6A *2) • Built-in ON / OFF circuit: Ensures long battery life. • Pull-down resistor is selectable. • Discharge shunt function is selectable. • Operation temperature range: Ta = −40°C to +85°C • Lead-free (Sn 100%), halogen-free *1. Please make sure that the loss of the IC will not exceed the power dissipation when the output current is large. *2. Types in which output voltage is externally set are unavailable. Applications • Constant-voltage power supply for battery-powered device • Constant-voltage power supply for TV, notebook PC and home electric appliance • Constant-voltage power supply for portable equipment Packages • HSOP-8A • HSOP-6 • SOT-89-5 • HSNT-6A |
