Product Information

Rev.1.1_00 www.DataSheet4U.com ULTRA-LOW CURRENT CONSUMPTION 150 mA VOLTAGE REGULATOR WITH BUILT-IN HIGH-ACCURACY VOLTAGE DETECTOR AND RESET INPUT FUNCTION S-1702 Series 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 protector 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: • High-accuracy output voltage: • Ultra-low current consumption: • High peak current capability: • Built-in on/off discharge circuit: • High ripple rejection: • Built-in overcurrent protector: 1.5 V to 5.5 V, selectable in 0.05 V step ±1.0% Current consumption of regulator block: 9 µA typ., 16 µA max. 150 mA output (at VIN ≥ VOUT(S) + 1.0 V)*1 Longer battery life, discharges output load instantaneously 70 dB typ. (at 1.0 kHz) limits overcurrent of output transistor Detector block • Output voltage: 1.3 V to 5.2 V, selectable in 0.05 V step • Built-in high-accuracy voltage detector: ±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 *2 • Ultra-low current consumption: During operation : 10 µA typ., 18 µA max. • Small package: SNT-6A • Lead-free product *1. *2. Attention should be paid to the power dissipation of the package when the output current is large. 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 phones • Power supply circuit block for health care products • Power supply circuit block for various mobile devices Package Package Name SNT-6A Package PG006-A Drawing Code Tape Reel PG006-A PG006-A Land PG006-A Seiko Instruments Inc. 1 ULTRA-LOW CURRENT CONSUMPTION 150 mA VOLTAGE REGULATOR WITH BUILT-IN HIGH-ACCURACY VOLTAGE DETECTOR AND RESET INPUT FUNCTION www.DataSheet4U.com S-1702 Series Block Diagrams 1.
