LOW NOISE 150mA LDO REGULATOR
R1113Z SERIES
OUTLINE
NO. EA-101-0504
The R1113Z Series are CMOS-based voltage regulator ICs with high output voltage accuracy, extremely low supply current, low ON-resistance, and high ripple rejection. Each of these ICs consists of a voltage reference unit, an error amplifier, resistors, a current limit circuit, and a chip enable circuit. These ICs perform with low dropout voltage and a chip enable function. The line transient response and load transient response of the R1113Z Series are excellent, thus these ICs are very suitable for the power supply for hand-held communication equipment. The output voltage of these ICs is fixed with high accuracy. Since the package for these ICs is WL-CSP4-P1 (Wafer Level CSP), high density mounting of the ICs on boards is possible.

In these ICs, fluctuation of output voltage, VOUT is detected by feedback registers R1, R2, and the result is compared with a reference voltage by the error amplifier, so that a constant voltage is output. A current limit circuit for protection in short mode and a chip enable circuit, are included.

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). We use Ceramic Capacitors for evaluation of these ICs. Recommended Capacitors ; GRM40X5R225K6.3 (Murata) GRM40-034X5R335K6.3 (Murata) GRM40-034X5R475K6.3 (Murata) (Note: When the additional ceramic capacitors are connected 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 2.2F 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.

When using these ICs, consider the following points: 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) of which is in the range described as follows:

(Note: If additional ceramic capacitors are connected to the Output Pin with 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.) (1) VIN=VOUT+1V (2) Frequency Band: 10Hz to 1MHz (3) Temperature: 25C R1113Z201B
