Variable Output LDO Regulator
BD00D0AWHFP
No.11023EBT04
Description
The BD00D0AWHFP is low-saturation regulator. The output voltage can be arbitrarily configured using the external
resistance. This IC has a built-in over-current protection circuit that prevents the destruction of the IC due to output short
circuits and a thermal shutdown circuit that protects the IC from thermal damage due to overloading.
Features
1) Output Current : 2A
2) High Output Voltage Precision : ±1%
3) Low saturation with PDMOS output
4) Built-in over-current protection circuit that prevents the destruction of the IC due to output short circuits
5) Built-in thermal shutdown circuit for protecting the IC from thermal damage due to overloading
6) Low ESR Capacitor
7) HRP5 packaging
Applications
Audiovisual equipments, FPDs, televisions, personal computers or any other consumer device

When using at temperatures over Ta=25, please refer to the heat reducing characteristics shown in Fig.15. and Fig.16.
The IC characteristics are closely related to the temperature at which the IC is used, so it is necessary to operate the IC
at temperatures less than the maximum junction temperature Tjmax.
Fig.15 and Fig.16 shows the acceptable loss and heat reducing characteristics of the HRP5 package. Even when the
ambient temperature Ta is a normal temperature (25), the chip (junction) temperature Tj may be quite high so please
operate the IC at temperatures less than the acceptable loss Pd.
The calculation method for power consumption Pc(W) is as follows :(Fig.16)
Pc=(VccVo)×Io+Vcc×Ib
Acceptable loss PdPc
Solving this for load current Io in order to operate within the acceptable loss,
Vcc: Input voltage
Vo: Output voltage
Io: Load current
Ib: Circuit current
Ishort: Short current
IoPdVcc×Ib
VccVo
(Please refer to Fig.9 for Ib.)
It is then possible to find the maximum load current IoMax with respect to the applied voltage Vcc at the time of thermal
design.
Calculation Example)When Ta=85,Vcc=10V,Vo=5V
Io3.79610×Ib
5
Io758.2mA (Ib:0.5mA)
Fig.16:θja=17.1/W -58.4mW/
25=7.3W 85=3.796W
Please refer to the above information and keep thermal designs within the scope of acceptable loss for all operating
temperature ranges. The power consumption Pc of the IC when there is a short circuit (short between Vo and GND) is :
Pc=Vcc×(Ib+Ishort)
(Please refer to Fig. 5 for Ishort)
