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
„ Output voltage accuracy: ± 2%.
„ Reference voltage accuracy: ± 2%
„ Ceramic capacitor can be used to prevent output
oscillation (BA3259HFP)
„ Low dissipation with two voltage input supported
(BA30E00WHFP)
„ Built-in thermal shutdown circuit
„ Built-in overcurrent protection circuit
