R1191x SERIES
300mA LDO REGULATOR with the Reverse Current Protection
NO.EA-229-111026
OUTLINE
R1191x Series are a low supply current voltage regulator with high output voltage accuracy. The maximum
operating voltage is 16V. These ICs can switch to the fast mode and the low power mode by the low power / fast
mode changer pin (ECO pin) without changing the output voltage value.
Each of these ICs consists of a voltage reference unit, an error amplifier, a resistor-net for voltage setting, a
short current limit circuit, a thermal shutdown circuit and a chip enable circuit.
Moreover, the R1191x Series has the reverse current protection function, which protects the reverse current
flow into V
DD
pin when the output pin voltage becomes higher than the V
DD
pin voltage. Thus it is suitable for the
back-up circuit.
Since the packages for these ICs are SOT-89-5, SOT-23-5 and DFN1616-6, therefore high density mounting
of the ICs on boards is possible.
