SOT23-5 3-MODE 200mA LDO REGULATOR
R1160N SERIES
■ 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.

■ TECHNICAL NOTES
When using these ICs, consider the following points:
Phase Compensation
In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For this purpose, be
sure to use a 2.2µF or more capacitor COUT with good frequency characteristics and ESR (Equivalent Series Resistance).
(Note: When the additional ceramic capacitors are connected to the Output Pin with Output capacitor for phase compensation,
the operation might be unstable. Because of this, test these ICs with as same external components as ones to be used on the
PCB.)
PCB Layout
Make VDD and GND line sufficient. When the impedance of these is high, it would be a cause of picking up the noise or
unstable operation. Connect a capacitor with as much as 1.0µF capacitor between VDD and GND pin as close as possible.
Set external components, especially output capacitor as close as possible to the ICs and make wiring shortest.

■ TECHNICAL NOTES
When using these ICs, consider the following points:
In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For this purpose, be
sure to use a capacitor COUT with good frequency characteristics and ESR (Equivalent Series Resistance) of which is in the
range described as follows:
The relations between IOUT (Output Current) and ESR of Output Capacitor are shown below. The conditions when the white
noise level is under 40µV(Avg.) are marked as the hatched area in the graph.
<Test conditions>
(1) Frequency band: 10Hz to 2MHz
(2) Temperature: 25°C
