Texas Instruments TPS728 Linear Regulators
Texas Instruments TPS728 Linear Regulators are low-dropout (LDO) linear regulators with a selectable dual-voltage level output. The Texas Instruments TPS728 Linear Regulators are designed for applications that require output voltage regulation and are specified for operation over a –40°C to +125°C range. Programming fuses and memory cards, reducing leakage effects, and conserving power in nanometric processes are some application examples.
