RICOH R5324D002B

R5324D SERIES
CMOS 3ch-LDOs for RF Unit
NO. EA-099-0606
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, VOUT2, VOUT3 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.

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;
