OUTLINE

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.

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.

SOT-23-5 and SON-6 packages, high density mounting of the ICs on boards is possible.

FEATURES

APPLICATIONS

3-MODE 200mA LDO REGULATOR

The R1160x Series consist of CMOS-based voltage regulator ICs with high output voltage accuracy, low

These ICs perform with low dropout voltage and a chip enable function. To prevent the destruction by over
