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 supply 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.

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 possible. • Set external components as close as possible to the ICs and make wiring short. 18 R N5RZ POWER DISSIPATION The power dissipation of RN5RZ series (SOT-23-5) is measured.
