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
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
