Documents Flashcards Grammar checker. These 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.

High output voltage accuracy: Includes switch Integrated overcurrent protection to protect the IC from damage caused by output short-circuiting. Integrated thermal shutdown to protect the IC from overheating at overload conditions. Low ESR ceramic capacitor can be used as output capacitor. Pin Name Function Pin No. Not connected 4 N. Only includes enable input Figure 8.

In this event it also becomes impossible to determine the cause of the damage e. Bd4433, 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.

Transient characteristics should be sufficiently verified. 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. 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.

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. The absolute maximum rating of the Pd stated in this specification is when the IC is mounted on a 70mm X 70mm X 1.

In case of exceeding this absolute maximum rating, increase the board size and copper area to prevent exceeding the Pd rating. 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. 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.

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.

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 b4d33 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 datasheeg the IC from heat damage. We also recommend using reverse polarity diodes in series or a bypass between all pins and the VCC pin.

For example, in case a resistor and a transistor are connected to the pins as shown bd33 the figure below then: 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 dayasheet input pin that is lower than the P substrate GND. A customer may use this translation version only datxsheet a reference to help reading the formal version.
