R1161x SERIES
3-MODE 300mA LDO REGULATOR
NO.EA-106-100218

OUTLINE
The R1161x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, low supply
current, and low ON-resistance. Each of these voltage regulator ICs consists of a voltage reference unit, an error
amplifier, resistors for setting output voltage, a current limit circuit, and a chip enable circuit.
These ICs perform with low dropout voltage and a chip enable function. To prevent the destruction by over
current, current limit circuit is included. The R1161x Series have 3-mode. One is standby mode with CE or
standby control pin. Standby mode realizes ultra small consumption current off mode. Other two modes are
realized with ECO pin. Fast Transient Mode (FT mode) and Low Power Mode (LP mode) are alternative with
ECO pin. Consumption current is reduced at Low Power Mode compared with Fast Transient Mode. Output
voltage is maintained between FT mode and LP mode.
The output voltage of these ICs is internally fixed with high accuracy. Since the packages for these ICs are
SOT-23-5, SON-6, and HSON-6, high density mounting of the ICs on boards is possible.
