R1118x SERIES

AUTOMATIC MODE SHIFT / 150mA LOW VOLTAGE REGULATOR

NO.EA-175-130411

OUTLINE

R1118x Series are CMOS-based voltage regulator ICs with ultra low supply current (Typ.5.5μA), and

remarkable improved transient response compared with the conventional low supply current voltage regulator.

The supply current of these ICs is automatically shifts between fast mode and low power mode, it depending on

the load current. The current threshould is fixed internally. R1118x shifts from low power mode to fast response

mode at I

OUT

=7mA (Typ.) and shifts fast response mode to low power mode at I

OUT

=2mA (Typ.).

These ICs are capable of the low input voltage (Min.1.4V) and the output voltage range from 0.8V is possible.

The output voltage of R1118x is fixed in the IC.

Each of these ICs consists of a voltage reference unit, an error amplifier, a resister net for setting output

voltage, a current limit circuits for over-current.

A standby mode with ultra low supply current can be realized with the chip enable function.

Since the packages for these ICs are SOT-23-5 (Non-promotion) and DFN(PLP)1612-4B, therefore high

density mounting of the ICs on boards is possible.
