VOLTAGE REGULATOR
(with Wide Input Voltage Range) with RESET
R1150Hxxxx SERIES
1
R1150H_E.doc/2003/06/24
NO. EA-081-0305
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 de-
lay 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 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 V
OUT
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 cur-
rent would vary. Therefore, without the capacitors, C
IN
and C
OUT
, Output Voltage is regulated, but for more stable op-
eration, use 0.1F or more capacitors as C
IN
and C
OUT
. Wiring should be made as short as possible.
PCB layout
Current flows into wiring for V
DD
or GND, thus, if the impedance of the wiring is rather high, it may cause of mak-
ing noise or unstable operation, thus width and pattern should be enough wide to avoid such problems. Connect the
capacitor, C
IN
between V
DD
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 +150C (Typ.), the operation of regulator would stop. After that, when the junction temperature is equal
or less than +120C (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, Out-
put voltage would be unstable or indefinite, or unexpected current would flow internally.

Output Delay Time for Release V
DET
In the R1150Hxx1C/D can set an output delay time for release voltage detector with connecting a capacitor to C
D
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 C
D
pin is started to be charged,
as a result, C
D
pin voltage rises. When the C
D
pin voltage surpasses C
D
pin threshold voltage, the output voltage of the
voltage detector outputs "H".

Input Transient Response
If input transient is 0.12V/s or faster, the output response may be extremely worse than normal operation. In that
case, add a capacitor between V
IN
and GND, and make the transient speed of V
IN
slower than 0.12V/s.
