36V, 200mA LDO from TI for precision analog
applications
Texas Instruments has released the TPS7A30/TPS7A49, a 36V
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 a low 16uVrms of output noise. The
TPS7A30 generates 200mA, 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
output capacitance over 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.
The key features of TPS7A30 and TPS7A49 include:
--1.5 percent nominal accuracy over load, line and temperature
for better precision for VCOs, PLLs and ADCs.
--PSRR of 72dB at 1kHz 55dB 10kHz to 700kHz
--The TPS54260 is a 60V, 2.5A SWIFT converter.
--The TPS40057 is a wide-input synchronous PWM buck controller.
--The bq24610/7, a switch-mode standalone battery charger
ICs for 5-V to 28-V input applications.
Package: The TPS7A30 and TPS7A49 come in a MSOP-8
PowerPAD
Price:
The TPS7A30 is priced at each US$1.50 for 1000 unit quantities.
The TPS7A49 is priced at each US$1.10 for 1000 unit quantities.
The TPS7A30_49EVM-567 evaluation module is priced at US$20.
