SOT23-5 3-MODE 200mA LDO REGULATOR
R1160X SERIES
I
OUTLINE
The R1160X 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 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 package, high density mounting of the ICs on boards is possible.
