CMOS 3CH-LDOs for RF Unit R5320x Series NO. EA-063-0204 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 rejectio. 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.
