R1160x SERIES

3-MODE 200mA LDO REGULATOR

NO.EA-083-140530

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.
