R1150H SERIES
VOLTAGE REGULATOR (with Wide Input Voltage Range) with RESET
NO.EA-081-111027
OUTLINE
The R1150H series are CMOS-based voltage regulator (VR) ICs equipped with a voltage detector (VDET). VR
function of the R1150Hxxxx has features of low dropout voltage, high output voltage accuracy, and ultra-low
supply current. Each of the R1150HxxxA series includes also a chip enable circuit. The output of built-in voltage
detector is Nch open drain type. The R1150HxxxC/D have a pin for connecting external capacitor to set a certain
reset delay time instead of chip enable control pin.
The regulator output voltage and the detector threshold voltage are fixed in the IC, Output Voltage Accuracy is
±2.0%, while Detector Threshold Accuracy is ±2.5%. The R1150HxxxA (with chip enable function) and
R1150HxxxC series can supervise input voltage by the built-in detector. R1150HxxxB can supervise SENSE pin
voltage by the built-in detector. R1150HxxxD type can supervise VOUT voltage, or Regulator Output Voltage of this
IC itself.
Since the package for these ICs is the SOT-89-5 package, high density mounting of the ICs on boards is
possible.

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 0.1µF 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.

R1150H
Refer to the following formula for setting the voltage of output and detective value.
(VOUT × 0.975) − (-VDET × 1.10) > 0.2
Thermal Shutdown
Thermal shutdown function is included in the R1150HxxxA/B/C/D Series, when 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 +120°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 VIH and VIL. Unless otherwise,
Output voltage would be unstable or indefinite, or unexpected current would flow internally.
Output Delay Time for Release VDET
In the R1150Hxx1C/D can set an output delay time for release voltage detector with connecting a capacitor to
CD pin. When an input voltage (in the case of R1150Hxx1C) or an output voltage (in the case of R1150Hxx1D)
surpasses the release voltage of its voltage detector (+VDET), the capacitor which is connected to CD pin is started
to be charged, as a result, CD pin voltage rises. When the CD pin voltage surpasses CD pin threshold voltage, the
output voltage of the voltage detector outputs “H”.

Output Delay Time (tpLH)
Output delay time for release voltage detector can be calculated with the next formula:
tPLH=1.25/200×109×CD (sec)
Input Transient Response
If the input transient speed is equal or faster than 80mV/μs and the transient level difference is equal or more
than 1.5V, the output response may be extremely worse than normal operation. In that case, add a capacitor
between VIN and GND, and make the transient speed of VIN slower than 80mV/µs.
