■Directions for use
ꢀNotes on Use
1. In cases where there is no capacitance (CL), or the capacitance is small, or where a capacitor with an extremely low ESR value is used (e.g.
ceramic), please use a capacitor (CL = 1.0µF [Tantalum]) in order to stop oscillation that may occur as the phase margin becomes smaller.
2. To reduce impedance between the power supply and the IC's input pin, which in turn will stop oscillation resulting from input voltage changes,
connect a capacitor (CIN = more than 1.0µF, ESR low) to the input side of the IC. Further, operation may become unstable and oscillation may
occur shoud impedance up to the IC's input be high (a state which could be brought about by several factors including which devices are
added to the input side, the surrounding wiring and/or the input power supply.)
Stability can be improved by regulating increases in input capacitance and by reducing impedance.
3. The regulator's input pin (VIN) and power supply pin are the same. Also, the voltage detector's power supply and the voltage regulator's power
supply are the same. Therefore, to have the voltage detector operating normally, it is necessary to apply a voltage larger than the minimum
operating voltage (1.5V) to the power supply input pin (VIN).
4. With CMOS output, the detector's output voltage equals the regulator's output voltage following release. Possible changes in the regulator's
output voltage (VROUT), following regulator load changes, will be output at the detector's output pin (VDOUT).
5. As the operations of the detector will momentarily respond when steep rise and fall time voltages are input at the power supply pin (VIN),
please ensure that the VIN(VDIN) pin's input frequency's rise and fall time is more than 5µ sec/V.
6. When using with the detector input pin (VDIN) connected to the regulator output pin (VOUT), the detector will momentarily respond as a result of
transient output voltage changes brought about by the regulator's load changes. With large load currents and/or large load transitions from
1mA to 80mA for example, output voltage will momentarily drop, so please add a capacitor where CL=more than 4.7mF.

ꢀOperational Notes [Detector : CMOS Output ('High' level = VOUT)]
Timing Chart A (VIN=VDIN)
1. When a voltage greater than the release voltage (VDR) is applied to the voltage input pin (VIN, VDIN), input voltage (VIN, VDIN) will gradually fall.
When a voltage greater than the detect voltage (VDF) is applied to the voltage input pin (VIN, VDIN), the output pin(VDOUT) voltage will be equal
to the regulator's output voltage (VOUT).
* With N-ch open drain configurations a state of high impedance means that should the pin be pulled up, voltage will be equal to pull up
voltage.
2. When input voltage (VIN, VDIN) fall below detect voltage (VDF), output voltage (VDOUT) will be equal to ground level (VSS).
3. Should input voltage (VIN, VDIN) fall below the minimum operational voltage (VMIN), output will become unstable.
Should VDIN fall below VMIN, voltage at the output pin (VDOUT) will be equal to ground level (VSS) .
*With N-ch open drain configurations output will equal pull up voltage as the output pin is generally pulled up.
4. Should input voltage (VIN, VDIN) rise above ground voltage (VSS), output voltage (VDOUT) will equal ground level until the release voltage level
(VDR) is reached.
5. The output pin voltage (VDOUT) will be equal to the regulator output voltage (VOUT) when input voltage (VIN, VDIN) rises above release voltage.
*With N-ch open drain configurations it will be equal to the voltage dependent on pull up.
Timing Chart B (VIN=voltages above set-up voltage + input/output voltage differential, VDIN = sweep voltage)
Because a voltage higher than the minimum operating voltage is applied to the voltage input pin (VIN), ground voltage will be output at the
output pin (VDOUT) during stage 3. (Stages 1, 2, 4, 5 are the same as in A above).
Note : The difference between release voltage (VDR) and detect voltage (VDF) is the Hysteresis Range (6).
