3 Description
The TPS7A94 is an ultra-low-noise (0.46 μVRMS), lowdropout
(LDO) voltage regulator capable of sourcing
1 A with only 150 mV of dropout. The low dropout,
in conjunction with a wide bandwidth error amplifier,
allows for very high PSRR (110 dB at 1 kHz and
50 dB at 1 MHz) under low operating headroom
(500 mV) and high output current (750 mA).
The device output is adjustable from 0 V to 5.5 V with
an external resistor. With its wide input voltage range,
the device supports operation as low as 1.7 V and up
to 5.7 V. The device includes programmable current
limit, programmable PG threshold, and precision
enable, allowing better control in the application.
With its high-accuracy reference and wide-bandwidth
topology, the device can be easily paralleled to
achieve lower noise and higher current.
With 1 output voltage accuracy (over line, load,
and temperature) and soft-start capabilities to reduce
inrush current, the device is an excellent choice for
powering sensitive analog low-voltage devices.
