1 R8x SERIES Low Voltage 5mA LDO REGULATOR NO.EA--7 OUTLINE The R8x Series are CMOS-based positive voltage regulator ICs with high output voltage accuracy and low supply current. Each of these ICs consists of a voltage reference unit, an error amplifier, resistor-net for voltage setting, a current limit circuit which prevents the destruction by excess current, and so on. The output voltage of these ICs is fixed with high accuracy. The R8 Series has low dropout voltage caused by built in low on resistance transistor. Further, the consumption current of IC itself is Typ..µA at no load, at the same time, compared with the conventional low supply current regulator, transient response is improved in all the load range by our original seamless technology. Since the packages for these ICs are SOT--5 and ultra small PLP-, high density mounting of the ICs on boards is possible.

For this purpose, be sure to use a.µf or more capacitor CL (Ceramic type). If a tantalum capacitor is used, and its ESR (Equivalent Series Resistance) of CL is large, the loop oscillation may result. Because of this, select CL carefully considering its frequency characteristics. Mounting on Board Make VDD and GND lines sufficient. If their impedance is high, pick-up the noise or unstable operation may result. Connect the capacitor with a.µf or more between VDD and GND as close as possible. Set external components, especially the output capacitor, as close as possible to the ICs and make wiring as short as possible. (Refer to the typical application) 7
