Secondary LDO Regulators for Local Power Supplies
Dual-output Secondary
Fixed/Variable Output LDO Regulators
for Local Power Supplies
BA3259HFP,BA30E00WHFP
No.09026EAT02
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.
