3 Description
The TPS7A20 is an ultra-small, low-dropout (LDO)
linear regulator that can source 300mA of output
current. The TPS7A20 is designed to provide low
noise, high PSRR, and excellent load and line
transient performance that can meet the requirements
of RF and other sensitive analog circuits. Using
innovative design techniques, the TPS7A20 offers an
ultra-low noise performance without the addition of a
noise bypass capacitor. The TPS7A20 also provides
the advantage of low quiescent current, which can be
ideal for battery-powered applications. With an input
voltage range of 1.6V to 6.0V and an output range of
0.8V to 5.5V, the TPS7A20 can be used for a wide
variety of applications. The device uses a precision
reference circuit to provide a maximum accuracy of
1.5% over load, line, and temperature variations.
The TPS7A20 features an internal soft-start to lower
the inrush current, thus minimizing the input voltage
drop during start up. The device is stable with
small ceramic capacitors, allowing for a small overall
solution size.
The TPS7A20 has a smart enable input circuit with an
internally controlled pulldown resistor that keeps the
LDO disabled even when the EN pin is left floating
and helps eliminate the external components used to
pulldown the EN pin.
