Regulator
BD7xxL5FP-C
●General Description
The BD7xxL5FP-C Series are low quiescent regulators
featuring 50V absolute maximum voltage, and output
voltage accuracy of ±2%, 500mA output current and 6μA
(Typ.) current consumption. There regulators are
therefore ideal for applications requiring a direct
connection to the battery and a low current consumption.
Ceramic capacitors can be used for compensation of the
output capacitor phase. Furthermore, these ICs also
feature overcurrent protection to protect the device from
damage caused by short-circuiting and an integrated
thermal shutdown to protect the device from overheating
at overload conditions.

●Selection of Components Externally Connected
・VCC pin
Insert capacitors with a capacitance of 0.1μF or higher between the VCC and GND pin. Choose the capacitance
according to the line between the power smoothing circuit and the VCC pin. Selection of the capacitance also
depends on the application. Verify the application and allow for sufficient margins in the design. We recommend
using a capacitor with excellent voltage and temperature characteristics.
・Output pin capacitor
In order to prevent oscillation, a capacitor needs to be placed between the output pin and GND pin. We recommend
using a capacitor with a capacitance of 4.7μF or higher. Electrolytic, tantalum and ceramic capacitors can be used.
When selecting the capacitor ensure that the capacitance of 4.7μF or higher is maintained at the intended applied
voltage and temperature range. Due to changes in temperature the capacitor’s capacitance can fluctuate possibly
resulting in oscillation. For selection of the capacitor refer to the IOUT vs. ESR data. The stable operation range
given in the reference data is based on the standalone IC and resistive load. For actual applications the stable
operating range is influenced by the PCB impedance, input supply impedance and load impedance. Therefore
verification of the final operating environment is needed.
When selecting a ceramic type capacitor, we recommend using X5R, X7R or better with excellent temperature and
DC-biasing characteristics and high voltage tolerance.
Also, in case of rapidly changing input voltage and load current, select the capacitance in accordance with verifying
that the actual application meets with the required specification.

Refer to the heat mitigation characteristics illustrated in Figure 25. and Figure 26. when using the IC in an environment of Ta≧
25°C. The characteristics of the IC are greatly influenced by the operating temperature, and it is necessary to operate under the
maximum junction temperature Timax.
Figure 25. and Figure 26. show the power dissipation and heat mitigation characteristics of the TO252-3 package. Even if the
ambient temperature Ta is at 25°C it is possible that the junction temperature Tj reaches high temperatures. Therefore, the IC
should be operated within the power dissipation range.
The following method is used to calculate the power consumption Pc (W)
Pc=(VCC-VOUT)×IOUT+VCC×Ib
Power dissipation Pd≧Pc

The load current Lo is obtained by operating the IC within the power dissipation range.

(Refer to Figure11. and Figure21. for the Ib)
Thus, the maximum load current IOUTmax for the applied voltage VCC can be calculated during the thermal design process.
Calculation example 1) with Ta=125℃, VCC=13.5V, VOUT=3.3V (TO252-3)

(Ib:6μA)
θja=26.0℃/W → -38.4mV/℃
25℃=4.8W → 125℃=0.953W
At Ta=125℃ with Figure 26 ③ condition, the calculation shows that ca 93mA of output current is possible at 10.2V potential
difference across input and output.

(Ib:6μA)
At Ta=125℃ with Figure 26 ③ condition, the calculation shows that ca 112mA of output current is possible at 8.5V potential
difference across input and output.

●Application Examples
・Applying positive surge to the VCC pin
If the possibility exists that surges higher than 50V will be applied to the VCC pin, a zenar diode should be placed
between the VCC pin and GND pin as shown in the figure below.
TO252-3
・Applying negative surge to the VCC pin
If the possibility exists that negative surges lower than the GND are applied to the VCC pin, a Shottky diode should be
place between the VCC pin and GND pin as shown in the figure below.
TO252-3
・Implementing a protection diode
If the possibility exists that a large inductive load is connected to the output pin resulting in back-EMF at time of startup
and shutdown, a protection diode should be placed as shown in the figure below.

●Operational Notes
1) Absolute maximum ratings
Exceeding the absolute maximum rating for supply voltage, operating temperature or other parameters can result in
damages to or destruction of the chip. In this event it also becomes impossible to determine the cause of the damage
(e.g. short circuit, open circuit, etc). Therefore, if any special mode is being considered with values expected to exceed
the absolute maximum ratings, implementing physical safety measures, such as adding fuses, should be considered.
2) The electrical characteristics given in this specification may be influenced by conditions such as temperature, supply
voltage and external components. Transient characteristics should be sufficiently verified.
3) GND electric potential
Keep the GND pin potential at the lowest (minimum) level under any operating condition. Furthermore, ensure that,
including the transient, none of the pin’s voltages are less than the GND pin voltage.
4) GND wiring pattern
When both a small-signal GND and a high current GND are present, single-point grounding (at the set standard point) is
recommended. This in order to separate the small-signal and high current patterns and to ensure that voltage changes
stemming from the wiring resistance and high current do not cause any voltage change in the small-signal GND. Similarly,
care must be taken to avoid wiring pattern fluctuations in any connected external component GND.
5) Inter-pin shorting and mounting errors
Ensure that when mounting the IC on the PCB the direction and position are correct. Incorrect mounting may result in
damaging the IC. Also, shorts caused by dust entering between the output, input and GND pin may result in damaging
the IC.
6) Inspection using the set board
The IC needs to be discharged after each inspection process as, while using the set board for inspection, connecting a
capacitor to a low-impedance pin may cause stress to the IC. As a protection from static electricity, ensure that the
assembly setup is grounded and take sufficient caution with transportation and storage. Also, make sure to turn off the
power supply when connecting and disconnecting the inspection equipment.
7) Power dissipation (Pd)
Should by any chance the power dissipation rating be exceeded the rise in temperature of the chip may result in
deterioration of the properties of the chip. The absolute maximum rating of the Pd stated in this specification is when the
IC is mounted on a 70mm X 70mm X 1.6mm glass epoxy board. In case of exceeding this absolute maximum rating,
increase the board size and copper area to prevent exceeding the Pd rating.
8) Thermal design
The power dissipation under actual operating conditions should be taken into consideration and a sufficient margin
should be allowed for in the thermal design. On the reverse side of the package this product has an exposed heat pad for
improving the heat dissipation. Use both the front and reverse side of the PCB to increase the heat dissipation pattern as
far as possible. The amount of heat generated depends on the voltage difference across the input and output, load
current, and bias current. Therefore, when actually using the chip, ensure that the generated heat does not exceed the
Pd rating.

9) Rapid variation in VCC voltage and load current
In case of a rapidly changing input voltage, transients in the output voltage might occur due to the use of a MOSFET as
output transistor. Although the actual application might be the cause of the transients, the IC input voltage, output current
and temperature are also possible causes. In case problems arise within the actual operating range, use
countermeasures such as adjusting the output capacitance.
10) Minute variation in output voltage
In case of using an application susceptible to minute changes to the output voltage due to noise, changes in input and
load current, etc., use countermeasures such as implementing filters.
11) Overcurrent protection circuit
This IC incorporates an integrated overcurrent protection circuit that is activated when the load is shorted. This protection
circuit is effective in preventing damage due to sudden and unexpected incidents. However, the IC should not be used in
applications characterized by continuous operation or transitioning of the protection circuit.
12) Thermal shutdown (TSD)
This IC incorporates and integrated thermal shutdown circuit to prevent heat damage to the IC. Normal operation should
be within the power dissipation rating, if however the rating is exceeded for a continued period, the junction temperature
(Tj) will rise and the TSD circuit will be activated and turn all output pins OFF. After the Tj falls below the TSD threshold
the circuits are automatically restored to normal operation.
Note that the TSD circuit operates in a situation that exceeds the absolute maximum ratings and therefore, under no
circumstances, should the TSD circuit be used in a set design or for any purpose other than protecting the IC from heat
damage.
13) In some applications, the VCC and pin potential might be reversed, possibly resulting in circuit internal damage or
damage to the elements. For example, while the external capacitor is charged, the VCC shorts to the GND. Use a
capacitor with a capacitance with less than 1000μF. We also recommend using reverse polarity diodes in series or a
bypass between all pins and the VCC pin.
14) This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them
isolated. P/N junctions are formed at the intersection of these P layers with the N layers of other elements to create a
variety of parasitic elements.
For example, in case a resistor and a transistor are connected to the pins as shown in the figure below then:
○ The P/N junction functions as a parasitic diode when GND > pin A for the resistor, or GND > pin B for the transistor.
○ Also, when GND > pin B for the transistor (NPN), the parasitic diode described above combines with the N layer of the
other adjacent elements to operate as a parasitic NPN transistor.
Parasitic diodes inevitably occur in the structure of the IC. Their operation can result in mutual interference between
circuits and can cause malfunctions and, in turn, physical damage to or destruction of the chip. Therefore do not employ
any method in which parasitic diodes can operate such as applying a voltage to an input pin that is lower than the
(P substrate) GND.
