RICOH R5322N Technical data

R5322N SERIES

120mA 2ch LDO REGULATORS

NO.EA-077-0606

OUTLINE

The R5322N 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 and prolong the battery life of each system. The line transient response and load transient response of the R5322N 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-23-6W package, and include 2ch LDO regulators each, high density mounting of the ICs on boards is possible.

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 2.2µF or more capacitance C (Equivalent Series Resistance) of which is in the range described as follows:

The relations between I

OUT (Output Current) and ESR of Output Capacitor are shown below. The conditions

when the white noise level is under 40µV (Avg.) are marked as the hatched area in the graph. (Note: When a ceramic capacitor is connected to the Output Pin as Output capacitor for phase compensation, the operation might be unstable unless as much as 1W resistor is connected between the capacitor and GND instead of ESR. Test these ICs with as same external components as ones to be used on the PCB.)

• Make V

DD 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 1µF or more between V

DD and GND as close as possible.

• Set external components, especially Output Capacitor, as close as possible to the ICs and make wiring

shortest.
