R1190x SERIES 1A VOLTAGE REGULATOR (Operating Voltage up to 16V) NO.EA-183-161011 OUTLINE The R1190x series are a low supply current voltage regulator with high output voltage accuracy. The maximum operating voltage is 16V and the output current is 1A. Each of these ICs consists of a voltage reference unit, an error amplifier, a resistor-net for voltage setting, as a short current protection, a peak current protection, a thermal shutdown, an inrush current limit and a chip enable circuit. The wide input voltage range (Max. 16V). Additionally, the output voltage is fixed internally, in the range from 2.0V to 12.0V by the 0.1V steps. The supply current of R1190x series is excellent (Typ. 150µA) moreover R1190x series has the standby mode (Typ. 0.1µA) by the chip enable function. Since the package for these ICs are TO-252-5-P2, SOT-89-5 and HSOP-6J with high power dissipation, high density mounting of the ICs on boards is possible.

Nippon Chemi-con Corporation KTD500B475M43A0T00 TECHNICAL NOTES When using these ICs, consider the following points: Phase Compensation In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For this purpose, use a capacitor COUT with good frequency characteristics and ESR (Equivalent Series Resistance). (Note: If additional ceramic capacitors are connected with parallel to the output pin with an output capacitor for phase compensation, the operation might be unstable. Because of this, test these ICs with as same external components as ones to be used on the PCB.) PCB Layout Make VDD and GND lines sufficient. If their impedance is high, noise pickup or unstable operation may result. Connect a capacitor with a capacitance value as much as 4.7µF or more between VDD and GND pin, and as close as possible to the pins. Set external components, especially the output capacitor, as close as possible to the ICs, and make wiring as short as possible. (Refer to the TYPICAL APPLICATION diagram above.) Thermal Shutdown There is the built-in thermal-shutdown function in R1190x series. It discontinues operation of the IC when the junction temperature becomes over 150°C (Typ.) and IC re-operates when the junction temperature under 130°C. If the temperature increasing keeps the IC repeats ON and OFF operating. The output becomes the pulse condition. Chip Enable Circuit For the output voltage stability, please do not use the intermediate electric potential (the voltage value between VCEH and VCEL) that causes the supply current increasing and the unstable of output voltage. 7 R1190x Inrush-Current Limit Function R1190x Series has the function to limit the inrush-current, it limited approximately 0.3A when the voltage regulator is turn ON. It is also possible to set time of the rush-current limitation by connecting capacitor with DELAY pin. The rush-current time (tD) and the value of capacitor (CD(F)) is calculatable by the following formula; tD=(0.000198+(3.79×107×CD))×VIN The inrush-current is limited even if the capacitor is not connected with the DELAY pin. In this case, the time is calculated as CD=0 by the formula above. Though, if the value of time is insufficient for controlling the inrush-current, please connect the capacitor with DELAY pin. The DELAY pin is used as OPEN when the capacitor is not used. Please use the DELAY pin as OPEN when the capacitor is not used. Auto-Discharge Function R1190xxxxD series has the auto-discharge function. When "L" signal is put into the Chip-enable pin (CE), the switch between VOUT and GND is turned ON and the charge at capacitor is discharge rapidly by the auto-discharge function. 8 R1190x TEST CIRCUITS VDD VOUT R1190x Series C2 C1 VIN CE GND DELAY V VOUT IOUT Basic Test Circuit VDD VOUT R1190x Series A C2 C1 CE GND DELAY VIN Test Circuit for Supply Current VDD R1190x Series Pulse Generator P.G.
