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

●Key Specification

 Input Power Supply Voltage: 25V (Max.)
 Output voltage type: Fixed
 Output current: BAxxDD0xx series 2A (Max.)

BAxxCC0xx series 1A (Max.)

 Shutdown current: 0μA(Typ.)
 Operating temperature range: -40℃ to +125℃

●Applications

Used in DSP power supplies for DVD and CD players,
FPDs, televisions, personal computers or any other
consumer device
