The SPX29300/01/02 are 3A, highly accurate voltage regulators with a low dropout voltage of 600mV (typical) at 3A.
These regulators are specifically designed for low voltage applications that require a low dropout voltage and a fast transient response. They are fully fault protected against overcurrent, reverse battery and positive and negative voltage transients. On-Chip trimming adjusts the reference voltage to 1% initial accuracy.
The SPX29300 is offered in a 3-pin TO-263 package, the SPX29301 is offered in a 5-pin TO-263 while the SPX29302 is offered in a 5-pin TO-263 and 5-pin TO-220 package.
- Adjustable output down to 1.25V
- 1% output accuracy
- Output current of 3A
- Low dropout voltage of 450mV @ 3A
- Extremely tight load and line regulation
- Extremely fast transient response
- Reverse battery protection
- Zero current shutdown (5-pin version)
- Error flag signal output for out of regulation state (5-pin version)
