Secondary Dual-Output

(Fixed/Variable) LDO Regulators

No.11026EBT02

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.
