Standard Variable Output LDO Regulators
2A Standard
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
●Absolute maximum ratings (Ta=25℃)
