Secondary LDO Regulators for Local Power Supplies Dual-output Secondary Fixed/Variable Output LDO Regulators for Local Power Supplies BA3259HFP,BA30E00WHFP 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 1) Output voltage accuracy: ± 2%. 2) Reference voltage accuracy: ± 2% 3) Output current capacity: 1 A (BA3259HFP), 0.6 A (BA30E00WHFP) 4) Ceramic capacitor can be used to prevent output oscillation (BA3259HFP) 6) Low dissipation with two voltage input supported (BA30E00WHFP) 7) Built-in thermal shutdown circuit 8) Built-in overcurrent protection circuit Applications Available to all commercial devices, such as FPD, TV, and PC sets besides DSP power supplies for DVD and CD sets.
