TI intros industry's first -36-V, 200-mA LDO

DALLAS, USA: Texas Instruments Inc. (TI) has introduced the industry's first -36-V low dropout regulators (LDO).

The TPS7A30, paired with the positive voltage TPS7A49, provides designers with a total solution for powering precision analog applications. The devices feature ultra-high power supply rejection ratio (PSRR) performance and as low as 16uVrms of output noise. The TPS7A30 generates 200 mA, while the TPS7A49 manages 150 mA.

"Customers designing high-precision equipment need clean bipolar power rails for powering operational amplifiers, analog-to-digital converters or digital-to-analog converters," said Sami Kiriaki, senior vice president and manager over TI's Power Management business unit. "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."

The TPS7A30/TPS7A49 linear regulator family is stable with any output capacitance greater than 2.2 uF. The LDOs come in an adjustable version with an output voltage ranging from 1.22 V to 34 V.

The LDOs are designed for noise-sensitive applications, such as test equipment; industrial, networking and telecom equipment; base stations; microwave and radio links; noise filtering for receive, transmit and power amplifiers; and medical applications.
