ꢀ 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 SON8 package, high density mounting of the ICs on boards is possible.

Fluctuation of each regulator’s output voltage, or VOUT1, 2 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 with a current limit circuit and stand-by mode is available by a chip enable
circuit.

ESR
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, or ESR value of external output capacitor with the stable area is shown below;
