R1172x SERIES
SUPER LOW ON RESISTANCE / LOW
VOLTAGE 1A LDO

OUTLINE
The R1172x Series are
CMOS-based positive
voltage regulator ICs. The R1172x Series have features of super low dropout, 1A output current capability. Even the output
voltage is set at 1.5V, on resistance of internal FET is typically 0.32Ω. Therefore, applications that require a large current at small dropout are suitable for the R1172x series. Low input
voltage is acceptable and low output
voltage can be set. The minimum input
voltage is 1.4V, and the lowest set output
voltage is 0.8V. Each of these ICs consists of a
voltage reference unit, an error amplifier, resistor net for setting output
voltage, a current limit circuit at over-current, a chip enable circuit, a thermal-shutdown circuit, and so on. A stand-by mode with ultra low consumption current can be realized with the chip enable pin. The output
voltage of R1172 is fixed in the IC.
Since the packages for these ICs are SOT-23-5, SOT-89-5, HSON-6...
