I OUTLINE
The R1154Hxxxx series are CMOS-based voltage regulator (VR) ICs. The R1154Hxxxxx has features of 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 R1154Hxxxx series.
The regulator output voltage is fixed in the R1154HxxxB, while adjustable type is the R1154H001C. Output
voltage accuracy is 2.0%.
Since the package for these ICs is the SOT-89-5 package with which high density mounting of the ICs on
boards is possible.

I TECHNICAL NOTES
Phase Compensation
Phase Compensation of the R1154 Series has been made internally for stable operation even though the load
current would vary. Therefore, without the capacitors, C
IN
and C
OUT
, the output voltage is regulated, however, for
more stable operation, use capacitors as C
IN
and C
OUT
. Especially, if the input line is long and impedance is high,
C
IN
is necessary, moreover, if you use C
OUT
, transient response will be improved. Recommended value is in the
range from 0.1F to 2.2F. Wiring should be made as short as possible.
Connect the capacitor, C
IN
between V
DD
pin and GND pin and C
OUT
between V
OUT
and GND as close as possible.

Thermal Shutdown
Thermal shutdown function is included in the R1154 Series, 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.
Chip Enable Circuit
Do not make voltage level of chip enable pin keep floating level, or in between V
IH
and V
IL.
Unless otherwise, Output
voltage would be unstable or indefinite, or unexpected current would flow internally.
