R1116x SERIES LOW NOISE 150mA LDO REGULATOR NO. EA-126-111026 OUTLINE The R1116x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, low supply current, low on Resistance, and high ripple rejection. Each of these ICs consists of a voltage reference unit, an error amplifier, resistor-net for voltage setting, a short current limit circuit, a chip enable circuit, and so on. These ICs perform with low dropout voltage and the chip-enable function. The supply current at no load of this IC is only 10μA, and the line transient response and the load transient response of the R1116x Series are excellent, thus these ICs are very suitable for the power supply for hand-held communication equipment. The supply current at no load of R1116x Series is remarkably reduced compared with R1114x Series. The mode change signal to reduce the supply current is not necessary. The output voltage accuracy is also improved. (±1.5%) The output voltage of these ICs is fixed with high accuracy. Since the packages for these ICs are SOT-23-5 and SON1612-6 therefore high density mounting of the ICs on boards is possible. R1126N Series that a pin configuration differs from R1116N Series are available. FEATURES • • • • • • • • • • • • Supply Current .....................................................................

Murata GRM155B30J105KE18B Kyocera CM05X5R105K06AB C1 Ceramic 1.0μF When using these ICs, consider the following points: 1.Mounting on PCB 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 1.0μF or more as C1 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. 2.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 C2 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.) If you use a tantalum type capacitor and ESR value of the capacitor is large, output might be unstable. Evaluate your circuit with considering frequency characteristics. Depending on the capacitor size, manufacturer, and part number, the bias characteristics and temperature characteristics are different. Evaluate the circuit with actual using capacitors. 20 R1116x ESR vs. Output Current When using these ICs, consider the following points: The relations between IOUT (Output Current) and ESR of an output capacitor are shown below.
