Texas Instruments introduces industry's first -36-V, 200-mA LDO
Low dropout regulators for powering precision analog improve efficiency and accuracy in noise-sensitive applications
DALLAS, Aug. 30 -- Texas Instruments Incorporated (TI) (NYSE: TXN) today 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. For details see: http://www.ti.com/tps7A30-pr.
"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.
Key features and benefits of the TPS7A30 and TPS7A49
-- Wide input voltages for robust tolerance of high line-voltage
transients: TPS7A30, -3.0V to - 36V, TPS7A49, +3.0V to +36V.
-- 1.5 percent nominal accuracy over load, line and temperature for
better precision for VCOs, PLLs and ADCs.
-- Stable with >2-uF ceramic output capacitor for smaller size and lower
cost versus tantalums.
-- Low noise/high PSRR for improved range in RF applications, filters,
and handling of DC/DC spikes.
-- Output noise as low as 16 uVRMS
-- PSRR of 72dB at 1kHz 55dB 10kHz to 700kHz
-- These LDOs for powering precision analog join several new power
management devices designed for the industrial market, including the
TPS54260, a 60-V, 2.5-A SWIFT converter; TPS40057 wide-input
synchronous PWM buck controller; and bq24610/7, switch-mode standalone
battery charger ICs for 5-V to 28-V input applications.
