LOW DROP-OUT AND LOW NOISE  
VOLTAGE REGULATOR  
RN5RZ SERIES  
OUTLINE  
The RN5RZ Series are voltage regulator ICs with high output voltage accuracy, low supply current, low dropout  
voltage and high ripple rejection developed through the use of a CMOS process. Each of these voltage regulator  
ICs consists of a voltage reference unit, an error amplifier, output voltage setting resistors, a current limit circuit and  
a chip enable circuit. (Provided two types of chip enable circuit ; “H” active and “L” active, that can be selected when  
order.)  
The output voltage of these ICs is fixed with high accuracy.  
In addition to low supply current from CMOS process, the RN5RZ Series may lengthen battery life through low  
dropout voltage and chip enable function thanks to the built-in low ON resistance transistor. Also when compared  
with conventional regulators that employ CMOS process, these ICs have superior ripple rejection, input transient  
response characteristic and load transient response characteristic thus making these product suitable for power sup-  
ply for hand-held communication equipment.  
Since the package for these ICs is the SOT-23-5 package, high density mounting of the ICs on boards is possible.

ABSOLUTE MAXIMUM RATINGS  
Absolute Maximum ratings are threshold limit values that must not be exceeded even for an instant under  
any conditions. Moreover, such values for any two items must not be reached simultaneously. Operation  
above these absolute maximum ratings may cause degradation or permanent damage to the device. These  
are stress ratings only and do not necessarily imply functional operation below these limits.

In these ICs, Output Voltage VOUT is detected by Feed-back Registers R1, R2, and the detected Output Voltage is  
compared with a reference voltage by an Error Amplifier, so that a constant voltage is output.  
A current limit circuit working for Short Protect and a chip enable circuit for standby function are included.

APPLICATION HINTS  
When using these ICs, be sure to take care regarding the following points :  
• In these ICs, phase compensation is made for securing stable operation even when the load current is var-  
ied. For this purpose, be sure to use a capacitor COUT with good frequency characteristics and ESR in the  
range described above.  
• Make VDD and GND line sufficient. When the impedance of these is high, the noise may be picked up or  
operation may become unstable.  
• Connect the capacitor with a capacitance of about 1µF between VDD and GND with wiring as short as possi-  
ble.  
• Set external components as close as possible to the ICs and make wiring short.
