The TPS7A94 is an ultra-low-noise
(0.46 µV RMS), low-dropout (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 the 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 the 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.
