R1173x SERIES

Super low on resistance/Low voltage LDO

NO.EA-123-080118

OUTLINE

The R1173x Series are CMOS-based positive voltage regulator ICs. The R1173x Series have features of

super low dropout, 1A output current capability, and -3mV typical load regulation at 1A. 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 R1173x 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 types of R1173 are fixed one in

the IC and adjustable one (R1173x001x).

Since the packages for these ICs are the SOT-89-5 package, HSON-6, or HSOP-6J, high density mounting of

the ICs on boards is possible.
