R5324D_E.doc/2003/02/10
CMOS 3CH-LDOs for RF Unit
R5324D SERIES
NO. EA-099-0301
OUTLINE
The R5324D Series are CMOS-based multi positive voltage regulator ICs with high output voltage accuracy, low
supply current, low noise, low dropout and high ripple rejection. The R5324D Series contain three voltage regulators.
Each of these voltage regulators in the R5324D Series consists of a voltage reference unit, an error amplifier, resistors
for setting output voltage, a short current limit circuit, a chip enable circuit, and so on.
The chip enable function contributes to prolong battery life. Further, regulators in the R5324D Series are with low
dropout voltage, excellent load transient response and line transient response, thus the R5324D series are very suitable for the power supply for hand-held communication equipment.
Since the package for these ICs is SON-8, high density mounting of the ICs on boards is possible.

Fluctuation of each regulator’s output voltage, or VOUT1, 2, 3 is detected individually. Then it is put back to an error
amplifier through feedback resistors, or R1_1, R2_1, R1_2, R2_2, R1_3, R2_3 and compared with a reference voltage
and compensated for the result and make a constant voltage.
In each regulator, short protection is made with a current limit circuit and stand-by mode is available by a chip enable circuit.

TECHNICAL NOTES
To use this IC, ESR of the output capacitors should be set in the range of the following graphs.
Noise level is measured with a spectrum analyzer and hatched area shows stable areas of which noise level is approximately equal or less than 40µV (Avg.). The relation between Load Current (IOUT) and Equivalent Series Resistors
(ESR) value of external output capacitor with the stable area is shown below;
