Secondary Fixed Output LDO Regulator Series for Local Power Supplies Dual-output Secondary Fixed Output LDO Regulators for Local Power Supplies BA3258HFP, BA33D15HFP, BA33D18HFP Description The BA3258HFP, BA33D15HFP, BA33D18HFP are fixed 2-output low-saturation regulators with a voltage accuracy at both outputs of 2%. These series incorporate both overcurrent protection and thermal shutdown (TSD) circuits in order to prevent damage due to output short-circuiting and overloading, respectively. Features 1) Output voltage accuracy: 2%. 2) Output current capacity: 1A (BA3258HFP), 0.5A (BA33D□□ Series) 3) A ceramic capacitor can be used to prevent output oscillation (BA3258HFP). 4) High Ripple Rejection (BA33D□□ Series) 5) Built-in thermal shutdown circuit 6) Built-in overcurrent protection circuit Applications FPDs, TVs, PCs, DSPs in DVDs and CDs Product Lineup Part Number Output voltage Vo1 Output voltage Vo2 Current capability Io1 Current capability Io2 Package BA3258HFP 3.3 V 1.5 V 1 A 1 A HRP5 BA33D15HFP 3.3 V 1.5 V 0.5 A 0.5 A HRP5 BA33D18HFP 3.3 V 1.8 V 0.5 A 0.5 A HRP5 Absolute Maximum Ratings BA3258HFP BA33D□□ Series Parameter Symbol Limits Units Parameters Symbol Limits Units Applied voltage VCC 15*1 V Applied voltage VCC 18*1 V Power dissipation Pd 2300*2 mW Power dissipation Pd 2300*2 mW Operating temperature range Topr −30 to 85 ℃ Operating temperature range Topr −25 to 105 ℃ Ambient storage temperature Tstg −55 to 150 ℃ Ambient storage temperature Tstg −55 to 150 ℃ Maximum junction temperature Tjmax 150 ℃ Maximum junction temperature Tjmax 150 ℃ *1 Must not exceed Pd *2.
