2A/1A Fixed Output LDO Regulators
BAxxDD0T Series BAxxCC0T Series BAxxCC0FP Series
2A/1A Fixed Output LDO Regulators
With Shutdown Swicth
BAxxDD0WT Series BAxxDD0HFP Series BAxxCC0WT Series BAxxCC0WFP Series
●General Description
Standard Fixed Output LDO Regulators are low-saturation regulators, available for output s up to 2A / 1A. ROHM has a
wide output voltage range and package lineup with and without shutdown switches. This IC has a built-in over-current
protection circuit that prevents the destruction of the IC due to output short circuits, a thermal shut-down circuit that protects
the IC from damage due to overloading and an over-voltage protection circuit that protects the IC from surges generated in
the power supply line of the IC.
●Features
±1% highly accurate output voltage (BAxxDD0xx)
Low saturation with PNP output
Built-in over-current protection circuit that prevents
the destruction of the IC due to output short circuits
Built-in thermal shutdown circuit for protecting the IC
from damage due to overloading
Built-in over- voltage protection circuit that prevents
the destruction of the IC due to power supply surges
