TECHNICAL NOTES
Phase Compensation
Phase Compensation of the R1150H Series has been made internally for stable operation even though the
load current would vary. Therefore, without the capacitors, CIN and COUT, Output Voltage is regulated, but for
more stable operation, use 0.1F or more capacitors as CIN and COUT. Wiring should be made as short as
possible.
PCB layout
Current flows into wiring for VDD or GND, thus, if the impedance of the wiring is rather high, it may cause of
making noise or unstable operation, thus width and pattern should be enough wide to avoid such problems.
Connect the capacitor, CIN between VDD pin and GND pin as close as possible.
About the output voltage and the detector threshold setting (In case of R1150HxxxD)
When the value difference between release voltage of voltage detector and the output voltage of voltage
regulator is little, the release function may not operate after detective, due to change the output voltage of
voltage detector. Pay attention for setting of the release voltage.
