| '2001.7.10 SOT23-6 150mA 2ch LDO REGULATORS R5323N SERIES s OUTLINE The R5323N Series are voltage regulator ICs with high output voltage accuracy, low supply current, low dropout, and high ripple rejection by CMOS process. 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. These ICs perform with low dropout voltage due to built-in transistor with low ON resistance, and a chip enable function prolongs the battery life of each system. The line transient response and load transient response of the R5323N 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 internally fixed with high accuracy. Since the package for these ICs is SOT-23-6 package, 2ch LDO regulators are included in each package, high density mounting of the ICs on boards is possible. s FEATURES Low Supply Current ..................................................

18 - s TECHNICAL NOTES 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 1.0F or more capacitance 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 in the typical characteristics above. The conditions when the white noise level is under 40V (Avg.) are marked as the hatched area in the graph. Test these ICs with as same external components as ones to be used on the PCB. Make VDD and GND line sufficient. When the impedance of these is high, the noise might be picked up or not work correctly. Connect the capacitor with a capacitance of 1F or more between VDD and GND as close as possible. Set external components, especially Output Capacitor, as close as possible to the ICs and make wiring shortest. Rev. 1.10 - 19 - |
