＊R1116Dxx1 (SON-6) and R1116Dxx2 (HSON-6) products are the discontinued product. As of March in 2018.

R1161x SERIES

3-MODE 300mA LDO REGULATOR

NO.EA-106-140530

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.
