The TPS7A19 is a low-dropout linear regulator (LDO) with a wide input voltage (VIN) range up to 40 V, capable of sourcing high output current (IOUT) up to 450 mA. This voltage regulator is ideal for generating a low-voltage supply from wide input-voltage rails. Not only does the TPS7A19 supply a well-regulated voltage rail, but the device also withstands and maintains regulation during voltage transients by acting as a simple surge protection circuit.
The TPS7A19 consumes only 15 µA of quiescent current (IQ) at light loads, thereby lowering the power consumption for always-on or battery-powered applications.
The TPS7A19 features integrated thermal shutdown and overcurrent protection. The TPS7A19 also offers a power good output (PG) with a programmable delay that indicates when the output voltage is in regulation. This feature is useful for power-rail sequencing functions.
This LDO is available in a small, 3-mm × 3-mm, thermally-enhanced, 8-pin SON package.
