TECHNICAL NOTES

Phase Compensation
Phase Compensation of the R1154x 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 0.1
μ
F to 2.2
μ
F. 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 R1154x Series, if the junction temperature is equal or more than
+150
°
C(Typ.), the operation of regulator would stop. After that, when the junction temperature is equal or less
than +125
°
C(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.
