●Description
BD357XFP/HFP SERIES regulators feature a high 50 V withstand-voltage and are suitable for use with onboard vehicle
microcontrollers. They offer the output current of 500 mA while limiting the quiescent current to 30μA (TYP).With these
devices, a ceramic capacitor can be selected at the output for stable operation, the output tolerance is within ±2% over the
wide ambient temperature range (-40 to 125℃), and the short circuit protection is folded-type to minimize generation of
heat during malfunction. These devices are developed to offer most robust power-supply design under the harsh
automotive environment. The BD357XFP/HFP Series provide ideal solutions to lower the current consumption as well as to
simplify the use with battery direct-coupled systems.
●Features
1) Ultra-low quiescent current: 30μA (TYP.)
2) Low-saturation voltage type P-channel DMOS output transistors
3) High output voltage precision:  2%/Iomax = 500 mA
4) Low-ESR ceramic capacitors can be used as output capacitors.
5) Vcc power supply voltage = 50 V
6) Built-in overcurrent protection circuit and thermal shutdown circuit
7) TO252-3, TO252-5, HRP5 Package
●Applications
Onboard vehicle devices (body-control, car stereos, satellite navigation systems, etc.)

Fig. 25
Refer to the heat mitigation characteristics illustrated in Figs. 23, 24 and 25 when using the IC in an environment where Ta
≧25℃. The characteristics of the IC are greatly influenced by the operating temperature. If the temperature is in excess of
the maximum junction temperature Tjmax, the elements of the IC may be deteriorated or damaged. It is necessary to give
sufficient consideration to the heat of the IC in view of two points, i.e., the protection of the IC from instantaneous damage
and the maintenance of the reliability of the IC in long-time operation.
In order to protect the IC from thermal destruction, it is necessary to operate the IC not in excess of the maximum junction
temperature Tjmax. Fig. 23 illustrates the power dissipation/heat mitigation characteristics for the TO252 package. Operate
the IC within the power dissipation Pd. The following method is used to calculate the power consumption PC (W).
Vcc : Input voltage
Vo : Output voltage
Io : Load current
Icc : Total supply current
PC=(VCC-VO)×IO+VCC×ICC
Power dissipation Pd≦PC
The load current IO is obtained to operate the IC within the power dissipation.
Pd-VCC×ICC
Io≦
(For more information about ICC, see page 12.)
VCC-VO
The maximum load current Iomax for the applied voltage VCC can be calculated during the thermal design process.
●Calculation example
Example: BD3571FP VCC = 12 V and VO = 5 V at Ta = 85℃
IO≦
0.624-12×ICC
IO≦89mA
12-5
θja=104.2℃/W→-9.6mAW/℃
25℃=1.2W→85℃=0.624W
(ICC=30μA)
Make a thermal calculation in consideration of the above so that the whole operating temperature range will be within the
power dissipation.
The power consumption Pc of the IC in the event of shorting (i.e., if the VO and GND pins are shorted) will be obtained from
the following equation.
Pc=VCC×(ICC+Ishort)

Technical Note
●Peripheral Settings for Pins and Precautions
1) VCC pins
Insert capacitors with a capacitance of 0.33μF to 1000μF between the VCC and GND pins.
The capacitance varies with the application. Be sure to design the capacitance with a sufficient margin.
2) Capacitors for stopping oscillation for output pins
Capacitors for stopping oscillation must be placed between each output pin and the GND pin. Use a capacitor within a
capacitance range between 0.1μF and 1000μF. Since oscillation does not occur even for ESR values from 0.001Ω to
100Ω, a ceramic capacitor can be used. Abrupt input voltage and load fluctuations can affect output voltages. Output
capacitor capacitance values should be determined after sufficient testing of the actual application.
●Operation Notes
1) Absolute maximum ratings
Use of the IC in excess of absolute maximum ratings such as the applied voltage or operating temperature range may
result in IC damage. Assumptions should not be made regarding the state of the IC (short mode or open mode) when
such damage is suffered. A physical safety measure such as a fuse should be implemented when use of the IC in a
special mode where the absolute maximum ratings may be exceeded is anticipated.
2) GND potential
Ensure a minimum GND pin potential in all operating conditions.
3) Setting of heat
Use a thermal design that allows for a sufficient margin in light of the power dissipation (Pd) in actual operating conditions.
4) Pin short and mistake fitting
Use caution when orienting and positioning the IC for mounting on printed circuit boards. Improper mounting may result in
damage to the IC. Shorts between output pins or between output pins and the power supply and GND pins caused by the
presence of a foreign object may result in damage to the IC.
5) Actions in strong magnetic field
Use caution when using the IC in the presence of a strong magnetic field as doing so may cause the IC to malfunction.
6) Testing on application boards
When testing the IC on an application board, connecting a capacitor to a pin with low impedance subjects the IC to stress.
Always discharge capacitors after each process or step. Be sure to turn power off when mounting or dismounting jigs at
the inspection stage. Furthermore, for countermeasures against static electricity, ground the equipment at the assembling
stage and pay utmost attention at the time of transportation or storing the product.
7) This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them isolated.
PN junction is formed by the P layer and the N layer of each element, and a variety of parasitic elements will be
constituted.
For example, when a resistor and transistor are connected to pins as shown in Fig. 19,
 the P/N junction functions as a parasitic diode when GND>Pin A for the resistor or GND>Pin B for the transistor
(NPN).
 Similarly, when GND>Pin B for the transistor (NPN), the parasitic diode described above combines with the N
layer of other adjacent elements to operate as a parasitic NPN transistor.

Technical Note
The formation of parasitic elements as a result of the relationships of the potentials of different pins is an inevitable result of
the IC's architecture. The operation of parasitic elements can cause interference with circuit operation as well as IC
malfunction and damage. For these reasons, it is necessary to use caution so that the IC is not used in a way that will
trigger the operation of parasitic elements, such as by the application of voltages lower than the GND (P substrate) voltage
to input pins.

8) Ground wiring patterns
When using both small signal and large current GND patterns, it is recommended to isolate the two ground patterns,
placing a single ground point at the application's reference point so that the pattern wiring resistance and voltage
variations caused by large currents do not cause variations in the small signal ground voltage. Be careful not to change
the GND wiring pattern of any external parts, either.
9) SW Pin
Do not apply the voltage to SW pin when the VCC is not applied.
And when the VCC is applied, the voltage of SW pin must not exceed VCC.
10) Thermal shutdown circuit (TSD)
This IC incorporates a built-in thermal shutdown circuit for the protection from thermal destruction. The IC should be used
within the specified power dissipation range. However, in the event that the IC continues to be operated in excess of its
power dissipation limits, the attendant rise in the chip's temperature Tj will trigger the thermal shutdown circuit to turn off
all output power elements. The circuit automatically resets once the chip's temperature Tj drops.
The thermal shutdown circuit operates if the IC is under conditions in express of the absolute maximum ratings. Never
design sets on the premise of using the thermal shutdown circuit. (See Fig. 8)
11) Overcurrent protection circuit (OCP)
The IC incorporates a built-in overcurrent protection circuit that operates according to the output current capacity. This
circuit serves to protect the IC from damage when the load is shorted. The protection circuit is designed to limit current
flow by not latching in the event of a large and instantaneous current flow originating from a large capacitor or other
component. These protection circuits are effective in preventing damage due to sudden and unexpected accidents.
However, the IC should not be used in applications characterized by the continuous operation or transitioning of the
protection circuits. At the time of thermal designing, keep in mind that the current capability has negative characteristics to
temperatures. (See Fig. 3)
