Standard Variable Output LDO Regulators
1A Standard
Variable Output LDO Regulators
BD00C0AWFP,BD00C0AWCP-V5
No.11023EBT03
●Description
The BD00C0AW Series is low-saturation regulators. 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: 1A
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) TO252-5,TO220CP-V5 packaging
●Applications
Audiovisual equipments, FPDs, televisions, personal computers or any other consumer device
