Texas Instruments has introduced its first -36V low dropout regulator (LDO).
The chip has a specified power supply rejection ratio (PSRR) of just 16µVrms of output noise.
Designed for noise-sensitive applications, such as test equipment, industrial and microwave links, the two devices in the family, the TPS7A30 and the TPS7A49 have current outputs of 200mA and 150mA, respectively.
"Customers designing high-precision equipment need clean bipolar power rails for powering operational amplifiers, analogue-to-digital converters or digital-to-analog converters,” said Sami Kiriaki, senior v-p at TI’s Power Management business.
“The TPS7A30 and TPS7A49 power for precision analog LDOs help meet that requirement with wide input voltages, lowest noise and maximum amount of transient headroom,” said Kiriaki.
The regulators are designed to be stable with any output capacitance greater than 2.2µF.
The LDOs come in an adjustable version with an output voltage ranging from 1.22V to 34V.
