300 mA very low quiescent current Linear regulator IC with automatic Green mode
Key Specifications
| Complete manufacturer part number | LD39130SJ30R |
|---|---|
| Manufacturer | STMicroelectronics |
| Description | 300 mA very low quiescent current Linear regulator IC with automatic Green mode |
| Package / case | Flip-Chip 4 |
| Product category | Linear regulators |
| Pins | 4 |
| Exact-order catalog temperature fields (manufacturer card; domain unspecified) | -40 °C to85 °C; the original card does not specify TA versus TJ. |
| Operating junction temperature (TOP; manufacturer datasheet) | -40 °C to125 °C. Own cover explicitly specifies operating temperature and Table2 identifies TOP as operating junction range. |
| Electrical-characteristics scope (manufacturer datasheet) | Typical/default conditions TJ25 °C; particular fixed-version limits separately specify -40<TJ<125 °C. Read parameter-specific VIN/load/voltage conditions; this is not a blanket production-test claim. |
| Operating temperature (manufacturer ordering record) | -40.0 °C to 85.0 °C |
| Packing type | Tape And Reel |
| RoHS compliant | Ecopack2 |
| Grade | Industrial |
