ETC R1150HXXXX

2002.Jul.29
VOLTAGE REGULATOR (with Wide Input Voltage Range) with RESET
R1150Hxxxx series
n OUTLINE
The R1150Hxxxx series are CMOS-based voltage regulator (VR) ICs equipped with a voltage detector (V DET ).
VR function of the R1150Hxxxx has features of low dropout voltage, high output voltage accuracy, and ultra-low
supply current. Each of the R1150HxxxA types includes also a chip enable circuit. The output of built-in voltage
detector is Nch open drain type. The R1150HxxxC/D types 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. The output voltage
accuracy is ±2.0%, while the detector threshold accuracy is ±2.5%. The R1150HxxxA (with chip enable function)
and C series can supervise input voltage by the built-in detector. R1150HxxxB type can supervise SENSE pin
voltage by the built-in detector. R1150HxxxD type can supervise VOUT voltage, or the 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.

n 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 capacitors as CIN and COUT. Recommended value is in the range from 0. 1µF to 1.0µF. 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.

R1150HxxxA Typical Application
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 V IL. 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 (+V DET ), 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”.
