1A Secondary LDO Regulators
for Local Power Supplies
BA□□BC0 Series,BA□□BC0W Series,BA00BC0W Series
No.10024EBT02
Description
The BA□□BC0 are low-saturation regulators with an output current of 1.0 A and an output voltage accuracy of 2%. A
broad output voltage range is offered, from 1.5V to 10V, and built-in overcurrent protection and thermal shutdown (TSD)
circuits prevent damage due to short-circuiting and overloading, respectively.
Features
1) Output current: 1 A (min.)
2) Output voltage accuracy: 2%
Broad output range available: 1.5 V -10 V (BA□□BC0 series)
3) Low saturation-voltage type with PNP output
4) Built-in overcurrent protection circuit
5) Built-in thermal shutdown circuit
6) Integrated shutdown switch (BA□□BC0WT, BA□□BC0WT-5, or BA□□BC0WFP Series, BA00BC0WCP-V5)
7) Operating temperature range: 40°C to +105°C
Applications
All electronic devices that use microcontrollers and logic circuits
