R1131x SERIES
Low Voltage 300mA LDO REGULATOR
NO.EA-116-061102
OUTLINE
The R1131x Series are CMOS-based low voltage regulator ICs with output voltage range from 0.8V to 3.3V. The minimum operating voltage is 1.4V. Each of these voltage regulator ICs consists of a voltage reference unit, an error amplifier, resistors for setting output voltage, a current limit circuit, and a chip enable circuit. To prevent the destruction by over current, current limit circuit is included. Standby mode realizes ultra small consumption current. The output voltage of these ICs is internally fixed with high accuracy. Since the packages for these ICs are SOT-23-5, SON-6, and HSON-6, high density mounting of the ICs on boards is possible.

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, be sure to use a 1.0F or more capacitor COUT with good frequency characteristics and ESR (Equivalent Series Resistance). (Note: If a tantalum capacitor is connected to the Output pin for phase compensation, if the ESR value of the capacitor is too large, the operation might be unstable. Because of this, test these ICs with as same external components as ones to be used on the PCB.) Chip capacitor characteristics of Bias dependence and Temperature characteristics may vary depending on its size, manufacturer, and part number. PCB Layout Make VDD and GND lines sufficient. If their impedance is high, pick-up the noise or unstable operation may result. Connect a capacitor with as much as 1.0mF capacitor between VDD and GND pin as close as possible. Set external components, especially the output capacitor, as close as possible to the ICs, and make wiring as short as possible.

ESR vs. Output Current
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, be sure to use a capacitor COUT with good frequency characteristics and ESR (Equivalent Series Resistance) of which is in the range described as follows: The relations between IOUT (Output Current) and ESR of Output Capacitor are shown below. The conditions when the white noise level is under 40V(Avg.) are marked as the hatched area in the graph.
