RICOH R5321D

R5321D SERIES
CMOS 2ch-LDOs for RF Unit
NO. EA-062-0606
OUTLINE
The R5321D Series are CMOS-based 2 channels voltage regulator ICs with high output voltage accuracy,
extremely low supply current, low noise, low ON-resistance and high ripple rejection. The R5321D Series
contain two voltage regulators. Each of these voltage regulators in the R5321D Series consists of a voltage
reference unit, an error amplifier, resistors for setting output voltage, a current limit circuit and a chip enable
circuit.
The chip enable function contributes to prolong battery life. Further, regulators in the R5321D Series are with
low dropout voltage, excellent load transient response and line transient response, thus the R5321D Series are
very suitable for the power supply for hand-held communication equipment.
The output voltage of each regulator is fixed with high accuracy by laser trim.
Since the package for these ICs is SON-8 package, high density mounting of the ICs on boards is possible.

Fluctuation of each regulator’s output voltage, or VOUT1, VOUT2 is detected individually and put back to an error
amplifier through feedback resistors, or R1_1, R2_1, R1_2, R2_2 and compared with a reference voltage and
compensated for the result and make a constant voltage.
In each regulator, short protection is made by a current limit circuit and stand-by mode is available by a chip
enable circuit.

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;
