BA3259HFP-TR ROHM

Datasheet Dual-Output (Fixed/Variable) LDO Regulators BA3259HFP BA30E00WHFP General Description The BA3259HFP and BA30E00WHFP are 2-output, low-saturation regulators. These units have both a 3.3 V fixed output as well as a variable output with a voltage accuracy of 2%, and incorporate an overcurrent protection circuit to prevent IC destruction due to output shorting along with a TSD (Thermal Shut Down) circuit to protect the IC from thermal destruction caused by overloading. Features Packages W (Typ.) x D (Typ.) x H (Max.) Output voltage accuracy: 2%.
