Technical content

NO. EA-062-0606 OUTLINE The R5321D Series are CMOS-based 2 channels volt age 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 regu lators 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.
