OUTLINE
The R1154x is a voltage regulator (VR) featuring high output voltage accuracy and ultra-low supply current. A
peak current limit circuit, a short current limit circuit, and a thermal shutdown circuit are built in the R1154x.
The regulator output voltage is fixed in the R1154xxxxB, while adjustable type is the R1154x001C. The Output
voltage accuracy is ±2.0%.
Since the packages for these ICs are DFN1616-6, SOT-23-5, and SOT-89-5, high density mounting of the ICs
on boards is possible.

RECOMMENDED OPERATING CONDITIONS
All of electronic equipment should be designed that the mounted semiconductor devices operate within the
recommended operating conditions. The semiconductor devices cannot operate normally over the recommended

THEORY OF OPERATION
Thermal Shutdown
Thermal shutdown function is included in the R1154x, if the junction temperature is equal or more than +150C
(Typ.), the operation of regulator would stop. After that, when the junction temperature is equal or less than
+125C (Typ.), the operation of regulator would restart. Unless the cause of rising temperature would remove,
the regulator repeats on and off, and output waveform would be like consecutive pulses.

Figure 1. Adjustable Regulator (R1154x001C)
The Output Voltage of Regulator in R1154xxxxC may be adjustable for any output voltage between its
2.5 V reference and its VDD setting level. An external pair of resistors is required, as shown in Figure 1.
The complete equation for the output voltage is described step by step as follows.
I1 = IIC + I2 ................................................................................................................................ (1)
I2 = 2.5/R2 ................................................................................................................................ (2)
Thus,
I1 = IIC + 2.5/R2 ......................................................................................................................... (3)
Therefore,
VOUT = 2.5 + R1 x I1 .................................................................................................................. (4)
Put Equation (3) into Equation (4), then
VOUT = 2.5 + R1 x (IIC + 2.5/R2)
= 2.5 x (1 + R1/R2) + R1 x IIC ........................................................................................... (5)
In 2nd term, or R1 x IIC will produce an error in VOUT.
In Equation (5),
IIC = 2.5/RIC ............................................................................................................................... (6)
R1 x IIC = R1 x 2.5/RIC
= 2.5 x R1/RIC ............................................................................................................... (7)
For better accuracy, choosing R1 (<< RIC) reduces this error.
RIC of the R1154x001C is approximately Typ. 17 MΩ (Ta = 25C, guaranteed by design).
RIC could be affected by the temperature, therefore evaluate the circuit taking the actual conditions of use into
account when deciding the resistance values for R1 and R2.

TECHNICAL NOTES
Notes on Selecting Components
Capacitor CIN and COUT
Phase Compensation of the R1154x has been made internally for stable operation even though the load
current would vary. Therefore, without the capacitors, CIN and COUT, the output voltage is regulated, however,
for more stable operation, use capacitors as CIN and COUT. Especially, if the input line is long and impedance
is high, CIN is necessary, moreover, if you use COUT, transient response will be improved. Recommended
value is in the range from 0.1 F to 2.2 F. Wiring should be made as short as possible.
Connect the capacitor, CIN between VDD pin and GND pin and COUT between VOUT and GND as close as
possible.
Chip Enable Input
Do not make voltage level of chip enable pin keep floating level, or in between VIH and VIL. Unless otherwise,
Output voltage would be unstable or indefinite, or unexpected current would flow internally.
