OUTLINE
The R5320G Series are Multi voltage regulator ICs with high output voltage accuracy, extremely low supply current, low noise,
low ON-resistance and high ripple rejection by CMOS process. The R5320G Series contain three voltage regulators. Each of
these voltage regulators in the R5320G 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 R5320G Series are with low dropout
voltage, excellent load transient response and line transient response, thus the R5320G 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 are SSOP8G package, high density mounting of the ICs on boards is possible.
