*1. CIN is a capacitor for stabilizing the input.
*2. A ceramic capacitor can be used for CL besides a tantalum capacitor.
*3. In case of product with shutdown function.
Caution The above connection diagram and constant will not guarantee successful
operation.
Perform through evaluation using the actual application to set the constant.
Input capacitors(CIN): >1.0 µF.
Output capacitors(CL): >2.2 µF(tantalum capacitors) Or
>10.0 µF(aluminum capacitors).
■Technical Terms
1. Output capacitors (CL)
Output capacitors are generally used to stabilize regulation operation and to
improve transient response characteristics. But the HM53XX series can provide
stable operation without output capacitors. Capacitors are used only to improve
transient response characteristics. Output capacitors can hence be removed in
applications in which transient response can be negligible. When an output
capacitor is used, a low ESR (Equivalent Series Resistance) capacitor like ceramic
capacitor can also be used.
2. Output voltage (VOUT)
The accuracy of the output voltage is ± 2.0% guaranteed under the specified
conditions for input voltage, which differs depending upon the product items,
output current, and temperature.
Caution: If the above conditions change, the output voltage value may vary and go
out of the accuracy range of the output voltage. See the electrical
characteristics and characteristics data for details.
3. Line regulations (ΔVOUT1/ΔVIN*VOUT)
These parameters indicate the input voltage dependence on the output voltage. That
is, the values show how much the output voltage changes due to a change in the
input voltage with the output current remained unchanged.

4. Load regulation (ΔVOUT2)
This parameter indicates the output current dependence on the output voltage. That
is, the value shows how much the output voltage changes due to a change in the
output current with the input voltage remained unchanged.
5. Dropout voltage (Vdrop)
This parameter indicates the difference between the input voltage (VIN1) and the
output voltage when
output voltage falls to 98 % of VOUT(E) by gradually decreasing the input voltage
(VIN).
Vdrop = VIN1-[VOUT(E) × 0.98]
■Description of Operation
1.Basic Operation
Figure 8 shows the block diagram of the HM53XX series.The error amplifier compares
a reference voltage Vref with a part of the output voltage divided by the feedback
resistors Rs and Rf, and supplies the gate voltage to the output transistor,
necessary to ensure certain output voltage independent from change of input voltage
and temperature.

2.Output Transistor
The HM53XX Series uses a Pch MOS FET as the output transistor.
The voltage at VOUT must not exceed VIN+0.3V. When the VOUT voltage becomes higher
than that of VIN, reverse current flows and may break the regulator since a
parasitic diode between VOUT and VIN exists inevitably
3. Shutdown function (ON/OFF pin)
The ON/OFF pin controls the start and stop of the regulation operation.
When the ON/OFF pin is set to shutdown level, halting whole internal circuit and
turning off the Pch MOS FET between VIN and VOUT, current consumption is
drastically reduced. The voltage of the VOUT pin becomes VSS level due to the
internal resistance divider of several MΩ between VOUT and VSS. The ON/OFF pin
should not be left afloat since no pull-up nor pull-down is made internally as
shown in figure 9. Note also that a current will flow to the VIN side via the
parasitic diode inside the IC if a voltage of VIN + 0.3 V or more is applied. When
the shutdown function is not used, connect the pin to the VIN pin in case of
positive logic and to the VSS pin in case of negative logic.
When a regulation operation at light load less than 100 μA is halted, output
voltage may increase. If the increase of the output voltage should be avoided, pull
down the VOUT pin to the VSS level as soon as ON/OFF pin goes to the shutdown level.

4. Short-circuit protection
Installation of the short-circuit protection which protects the output transistor
against short-circuit between VOUT and VSS can be selected in the HM53XX series.
The short-circuit protection controls output current as shown in the typical
characteristics, (1) OUTPUT VOLTAGE versus OUTPUT CURRENT, and suppresses output
current at about 40 mA even if VOUT and VSS pins are short-circuited.
The short-circuit protection can not at the same time be a thermal protection.
Attention should be paid to the Input voltage and the load current under the actual
condition so as not to exceed the power dissipation of the package including the
case for short-circuit.
When the output current is large and the difference between input and output
voltage is large even if not shorted, the short-circuit protection may work and the
output current is suppressed to the specified value. Products without short-circuit
protection can provide comparatively large current by removing a short-circuit
protection.

■ Selection of External Components
Output Capacitor (CL)
The HM53XX series can provide stable operation without output capacitor (CL) since
the regulator has an internal phase compensation circuit to stabilize operation
when the load changes. The transient response of the regulator, however, changes
with the output capacitor and the magnitude of overshoot and undershoot on output
voltage accordingly changes. Please refer to CL dependence data in “Transient
Response Characteristics” to select suitable value for the capacitor.
When a tantalum or an aluminum electrolytic capacitor is used, the ESR of the
capacitor shall be 10Ω or less. When an aluminum electrolytic capacitor is used
attention should be especially paid to since the ESR of the aluminum electrolytic
capacitor increases at low temperature and possibility of oscillation becomes large.
Sufficient evaluation including temperature characteristics is indispensable.
■ Precautions:
·Design wiring patterns for VIN, VOUT and GND pins to hold low impedance.
When mounting an output capacitor between the VOUT and VSS pins (CL) and a
capacitor for stabilizing the input between VIN and VSS pins (CIN), the distance from
the capacitor to the VOUT pin and to the VSS pin should be as short as possible.
·Note that output voltage may be increased at low load current of less than 1 uA.
·To prevent oscillation, it is recommended to use the external parts under the
following conditions.
Equivalent Series Resistance (ESR): 30Ωor less
Input series resistance (RIN): 10Ωor less
·A voltage regulator may oscillate when power source impedance is high and input
capacitor is low or not connected.
·The application condition for input voltage and load current should not exceed the
package power dissipation.
·Pay attention to the operating conditions for input/output voltage and load current so
that the power loss in the IC does not exceed the power dissipation of the package.
·Do not apply an electrostatic discharge to this IC that exceeds the performance
ratings of the built-in electrostatic protection circuit.
·SII claims no responsibility for any and all disputes arising out of or in connection
with any infringement of the products including this IC upon patents owned by a third
party.
