CMOS 3ch-LDOs for RF Unit
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 packages for these ICs are SSOP8G, and SON8,
high density mounting of the ICs on boards is possible. |
