Single-Output LDO Regulator
35V Voltage Resistance
1A LDO Regulator
BD00C0AWFPS-M
●General
Description
The BD00C0AWFPS-M is a low-saturation regulator.
The output voltage can be arbitrarily configured
depending on the external resistor combination. This IC
has a built-in over-current protection circuit that prevents
the destruction of the IC due to output short circuit and a
thermal shutdown circuit that protects the IC from
thermal damage due to overloading.
●Features
Output Current capability : 1A
High Output Voltage Precision : ±1% (Ta=25℃)
Low saturation with PDMOS output
Built-in over-current protection circuit that prevents the
destruction of the IC due to output short circuit
Built-in thermal shutdown circuit for protecting the IC
from thermal damage due to overloading
Low ESR Capacitor
AEC-Q100 Qualified
●Applications
