R5320x SERIES
Discontinued
OUTLINE
The R5320x Series are CMOS-based multi voltage regulator ICs with high output voltage accuracy, extremely
low supply current, low noise, low ON-resistance and high ripple rejection. The R5320x Series contain three
voltage regulators. Each of these voltage regulators in the R5320x 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 R5320x Series are with
low dropout voltage, excellent load transient response and line transient response, thus the R5320x 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 SSOP8G and SON8, 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.

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;
