R1160x SERIES
3-MODE 200mA LDO REGULATOR
NO.EA-083-0511

OUTLINE
The R1160x Series consist of 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 R1160x Series have 3-mode. One is standby mode with CE or
standby control pin. 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 to 1/10 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 and SON-6 packages, high density mounting of the ICs on boards is possible.
