3 Description
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.
