continuation of production without notice for reasons such as improvement. Therefore, before deciding to use
the products, please refer to Ricoh sales representatives for the latest information thereon.
2. This application manual may not be copied or otherwise reproduced in whole or in part without prior written con-
sent of Ricoh.
3. Please be sure to take any necessary formalities under relevant laws or regulations before exporting or other-
wise taking out of your country the products or the technical information described herein.
4. The technical information described in this application manual shows typical characteristics of and example
application circuits for the products. The release of such information is not to be construed as a warranty of or a
grant of license under Ricoh's or any third party's intellectual property rights or any other rights.
5. The products listed in this document are intended and designed for use as general electronic components in
standard applications (office equipment, computer equipment, measuring instruments, consumer electronic
products, amusement equipment etc.). Those customers intending to use a product in an application requiring
extreme quality and reliability, for example, in a highly specific application where the failure or misoperation of
the product could result in human injury or death (aircraft, spacevehicle, nuclear reactor control system, traffic
control system, automotive and transportation equipment, combustion equipment, safety devices, life support
system etc.) should first contact us.
6. We are making our continuous effort to improve the quality and reliability of our products, but semiconductor
products are likely to fail with certain probability. In order prevent any injury to persons or damages to property
resulting from such failure, customers should be careful enough to incorporate safety measures in their design,
such as redundancy feature, fire-containment feature and fail-safe feature. We do not assume any liability or
responsibility for any loss or damage arising from misuse or inappropriate use of the products.
7. Anti-radiation design is not implemented in the products described in this application manual.
8. Please contact Ricoh sales representatives should you have any questions or comments concerning the prod-
ucts or the technical information.

OUTLINE
The R
5VL Series are voltage detector ICs with high detector threshold accuracy and ultra-low supply
current by CMOS process. Each of these ICs consists of a voltage reference unit, a comparator, resistors for
voltage detection, an output driver and a hysteresis circuit.
The detector threshold is fixed with high accuracy.
Two output Types, Nch open drain type and CMOS type, are available.
Three types of packages, TO-92, SOT-89 (Mini-power Mold), SOT-23-5 (Mini-mold), are available.
Ultra-low Supply Current................................TYP. 1.0A (V
DD
=3.0V)
Broad Operating Voltage Range......................1.5V to 10.0V
Detector Threshold...........................................Stepwise setting with a step of 0.1V in the range of
2.0V to 6.0V is possible (refer to Selection Guide).
High Accuracy Detector Threshold .................2.5%
Low Temperature-Drift Coefficient of Detector Threshold .....TYP.100ppm/C
Two Output Types ............................................Nch Open Drain and CMOS
Three Types of Packages..................................TO-92, SOT-89 (Mini-power Mold), SOT-23-5 (Mini-mold)

DET
+2.0V is applied to V
DD
is
Time A, and the time at which the output voltage reaches the voltage of (+V

Absolute Maximum ratings are threshold limit values that must not be exceeded even for an instant under any
conditions. Moreover, such values for any two items must not be reached simultaneously. Operation above
these absolute maximum ratings may cause degradation or permanent damage to the device. These are stress
ratings only and do not necessarily imply functional operation below these limits.

OPERATION
FIG. 1 Block Diagram
Operation Diagram
Step 1. Output Voltage is equal to Power Source Voltage (V
DD
).
Step 2. When Input Voltage to Comparator reaches the state of Vref
V
DD
(Rb+Rc)/(Ra+Rb+Rc)at Point A (Detected Voltage V
DET
), the output of Com-
parator is reserved, so that Output Voltage becomes GND.
Step 3. In the case of CMOS Output, Output Voltage becomes unstable when Supply Voltage (V
DD
) is smaller than Minimum Operating Voltage. In the
case of Nch Open Drain Output, a pulled-up voltage is output.
Step 4. Output Voltage becomes equal to GND.
Step 5. When Input Voltage to Comparator reaches the state of Vref
V
DD
(Rb)/(Ra+Rb) at Point B (Released Voltage +V
DET
), the output of Comparator is reserved,
so that Output Voltage becomes equal to Supply Voltage (V
DD
)

1. When R
5VL
C (CMOS Output) is used in FIG. 8, this IC may oscillate by the through-type current at the detec-
tion when impedance is connected between Power Source V
DD
and R
5VL V
DD
Pin.When R
5VL
A (Nch Open
Drain Output) is used in FIG. 8, and R becomes excessively large, Detector Threshold may be varied because of the
voltage drop of the supply current in the IC itself.
2. The connection as shown in FIG. 9 may cause the oscillation in both R
5VL
C (CMOS Output) and R
5VL
A
(Nch Open Drain Output).

TAPING SPECIFICATIONS
(Unit: mm)
TO-92
(Note) When taping is conducted, the pins of TO-92 are
subjected to a particular forming.
(Note) TZ type tape is not in the form of a reel, but is
packed in a zigzag state in a box.Therefore, the
tape can be used as either an RF type tape or an
RR type tape,depending upon the pulling out direc-
tion (B or F).
