SOT23-5 3-MODE 200mA LDO REGULATOR

R1160N SERIES

s

OUTLINE

The R1160N Series are voltage regulator ICs with high output voltage accuracy, low supply current, and low ON-resistance by

CMOS process. 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 R1160N 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 package for these ICs is SOT-23-5 package,

high density mounting of the ICs on boards is possible.
