Ti lancerer unik LDO-løsning

Texas Instruments introducerer industriens første -36V, 200-mA LDO (in english).

Texas Instruments (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, says 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.
