1 / 45 page  S-1702 Series www.sii-ic.com SUPER-LOW CURRENT CONSUMPTION 150 mA VOLTAGE REGULATOR WITH BUILT-IN HIGH-ACCURACY VOLTAGE DETECTOR AND RESET INPUT FUNCTION © SII Semiconductor Corporation, 2008-2015 Rev.2.2_01 1 The S-1702 Series, developed based on CMOS technology, is a 150 mA output positive voltage regulator with a low dropout voltage, a high-accuracy output voltage, and low current consumption. The S-1702 Series includes a voltage regulator with high-accuracy output voltage of ±1.0% allowing to use a ceramic capacitor of 1.0 μF or more, and a voltage detector that monitors the output/input voltage of the regulator. It also includes an overcurrent protection circuit that prevents the output current from exceeding the current capacitance of the output transistor and an output forcible discharge circuit for the regulator operation off. Small SNT-6A package is available for the S-1702 Series. And an external small capacitor can be used, enabling high-density mounting. Its super-low current consumption makes the S-1702 Series ideal for mobile devices. Features Regulator block • Output voltage: 1.5 V to 5.5 V, selectable in 0.05 V step • Output voltage accuracy: ±1.0% • Current consumption: Current consumption of regulator block: 9 μA typ., 16 μA max. • Output current: Possible to output 150 mA (VIN ≥ VOUT(S) + 1.0 V)*1 • Built-in overcurrent protection circuit: Limits overcurrent of output transistor. • Built-in ON / OFF forcible discharge circuit: Ensures long battery life, discharges output load instantaneously. • Ripple rejection: 70 dB typ. (f = 1.0 kHz) Detector block • Detection voltage: 1.3 V to 5.2 V, selectable in 0.05 V step • Built-in high-accuracy voltage detection circuit: ±1.0% Monitoring output/input or monitoring external input by option (detector output) • External reset input: Forcible assertion of detector output by external reset pin (RESX) input Overall • Correlation temperature gradient in the regulator and the detector blocks • Current consumption: During operation*2: 10 μA typ., 18 μA max. • Operation temperature range: Ta = −40°C to +85°C • 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. Excluding current flowing in pull-up and pull-down resistors connected to the ON / OFF or RESX pins Applications • Wireless power supply circuit block for cellular phone • Power supply circuit block for health care product • Power supply circuit block for various mobile device Package • SNT-6A |
