500-mA 3.3-V or 5.0-V Output
LDO Regulators
BD4xxM5-C Series
●General Description
●Features
The BD4xxM5 series are low quiescent regulators
featuring 45 V absolute maximum voltage, and output
voltage accuracy of ±2 % (3.3 V or 5 V: Typ.), 500 mA
output current and 38 μA (Typ.) current consumption.
These regulators are therefore ideal for applications
requiring a direct connection to the battery and a low
current consumption.
A logical “HIGH” at the CTL enables the device and
“LOW” at the CTL disables the device.
(Only W: Includes Enable Input).
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
Insert capacitors with a capacitance of 0.1 μF or higher between the VCC and the GND. Choose the capacitance
according to the line between the power smoothing circuit and the VCC. Selection of the capacitance also depends
on the application. Verify the application and allow 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. We recommend
using a capacitor with a capacitance of 10 μF (Typ.) or higher. Electrolytic, tantalum and ceramic capacitors can be
used. When selecting the capacitor ensure that the capacitance of 6 μF 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 data of Figure 41.
The stable operation range given in the data of Figure 41 and Figure 42 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 fluctuation of input voltage and load current, select the capacitance in accordance with
verifying that the actual application meets with the required specification. Mount the capacitor as much as possible
near connected pin.

●Thermal Design
This product exposes a frame on the back side of the package for thermal efficiency improvement.
Within this IC, the power consumption is decided by the dropout voltage condition, the load current and the circuit current.
Refer to power dissipation curves illustrated in Figure 44, 45 when using the IC in an environment of Ta ≥ 25 °C. Even if the
ambient temperature Ta is at 25 °C, depending on the input voltage and the load current, chip junction temperature can be
very high. Consider the design to be Tj ≤ Tjmax = 150 ℃ in all possible operating temperature range.
Should by any condition the maximum junction temperature Tjmax = 150℃ rating be exceeded by the temperature
increase of the chip, it may result in deterioration of the properties of the chip. The thermal impedance in this specification is
based on recommended PCB and measurement condition by JEDEC standard. Verify the application and allow sufficient
margins in the thermal design by the following method is used to calculate the junction temperature Tj.
Tj can be calculated by either of the two following methods.
1. The following method is used to calculate the junction temperature Tj.
Tj = Ta + PC × θJA

・Calculation Example(TO252-J5(F) / TO252-3)
If VCC = 13.5 V, VOUT = 5.0 V, IOUT = 200 mA, Icc = 38 μA, the power consumption Pc can be calculated as follows:
PC = (VCC - VOUT) × IOUT + VCC × Icc
= (13.5 V – 5.0 V) × 200 mA + 13.5 V × 38 μA
= 1.7 W
At the ambient temperature Tamax = 85°C, the thermal Impedance ( Junction to Ambient )θJA = 23 °C / W( 4-layer PCB ),
Tj = Tamax + PC × θJA
= 85 °C + 1.7 W × 23 °C / W
= 124.1 °C
When operating the IC, the top center of case’s (mold) temperature TT = 100℃、ΨJT = 17 °C / W( 1-layer PCB ),
Tj = TT + PC × ΨJT
= 100 °C + 1.7 W × 17 °C / W
= 128.9 °C
For optimum thermal performance, it is recommended to expand the copper foil area of the board, increasing the layer and
thermal via between thermal land pad.
・Calculation Example (TO263-5(F) / TO263-3(F))
If VCC = 13.5 V, VOUT = 5.0 V, IOUT = 200 mA, Icc = 38 μA, the power consumption Pc can be calculated as follows:
PC = (VCC - VOUT) × IOUT + VCC × Icc
= (13.5 V – 5.0 V) × 200 mA + 13.5 V × 38 μA
= 1.7 W
At the ambient temperature Tamax = 85°C, the thermal impedance ( Junction to Ambient )θJA = 21 °C / W( 4-layer PCB ),
Tj = Tamax + PC × θJA
= 85 °C + 1.7 W × 21 °C / W
= 120.7 °C
When operating the IC, the top center of case’s (mold) temperature TT = 100℃、ΨJT = 8 °C / W( 1-layer PCB ),
Tj = TT + PC × ΨJT
= 100 °C + 1.7 W × 8 °C / W
= 113.6 °C
For optimum thermal performance, it is recommended to expand the copper foil area of the board, increasing the layer and
thermal via between thermal land pad.

●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 potential at the lowest (minimum) level under any operating condition. Furthermore, ensure that,
including the transient, none of the pin’s voltage is less than the GND 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) CTL
Do not make voltage level of chip enable keep floating level, or in between VthH and VthL. Otherwise, the output voltage
would be unstable or indefinite.
6) 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 the GND may result in damaging
the IC.
7) 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.
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.
Should by any condition the maximum junction temperature Tjmax = 150℃ rating be exceeded by the temperature
increase of the chip, it may result in deterioration of the properties of the chip. The thermal impedance in this
specification is based on recommended PCB and measurement condition by JEDEC standard. Verify the application
and allow sufficient margins in the thermal design.
9) 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.
10) Thermal Shut Down (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.

11) In some applications, the VCC and the VOUT potential might be reversed, possibly resulting in circuit internal damage
or damage to the elements. For example, the accumulated charge in the output pin capacitor flowing backward from the
VOUT to the VCC when the VCC shorts to the GND. In order to minimize the damage in such case, use a capacitor with
a capacitance less than 1000 μF. Also by inserting a reverse polarity diode in series to the VCC, it can prevent reverse
current from reverse battery connection or the case. When the point A is short-circuited GND, if there may be any
possible case point B is short-circuited to GND, we also recommend using a bypass diode between the VCC and the
VOUT.

12) 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 the GND > pin A for the resistor, or the GND > pin B for the
transistor.
○ Also, when the 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.
