R1160N Series

3-MODE 200mA LDO REGULATOR

Data Sheet / Flyer

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^TM. Fast Transient Mode (FT mode) and Low Power Mode (LP mode) are alternative with ECO pin^TM. 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 (Non-promotion) packages, high density mounting of the ICs on boards is possible.

Note : Discontinued Products
SON-6 (R1160D Series) will be discontinued at the end of January, 2014.
