SBVS204A –JUNE 2012–REVISED JULY 2012

36-V, 1-A, 4.17-µV , RF LDO Voltage Regulator

RMS

FEATURES

DESCRIPTION

The TPS7A47 is a positive voltage (+36 V), ultralow-

•

Input Voltage Range: +3 V to +36 V

Output Voltage Noise

noise (4.17 µV_RMS) linear regulator capable of

•

sourcing a 1-A load.

–

4.17 µV_RMS(10 Hz, 100 kHz)

In addition, the TPS7A47 output voltage is fully user-

adjustable via a printed circuit board (PCB) layout

without the need of external resistors or feed-forward

capacitors, thus reducing overall component count.

•

Power-Supply Ripple Rejection:

–

82 dB (100 Hz)

≥ 55 dB (10 Hz, 10 MHz)

The TPS7A47 is designed with bipolar technology

ANY-OUT™ (User-Adjustable Output via

PCB Layout):

primarily

for

high-accuracy,

high-precision

instrumentation applications where clean voltage rails

are critical to maximize system performance. This

feature makes the device ideal for powering

operational amplifiers, analog-to-digital converters

(ADCs), digital-to-analog converters (DACs), and

other high-performance analog circuitry in critical

applications (such as medical, RF, and test-and-

measurement).

–

No External Resistors or Feed-Forward

Capacitors Required

–

Output Voltage Range: +1.4 V to +20.5 V

•

Output Current: 1 A

Dropout Voltage: 307 mV at 1 A

CMOS Logic Level-Compatible Enable Pin

Built-In Fixed Current Limit and

Thermal Shutdown

In addition, the TPS7A47 is ideal for post dc/dc

converter regulation. By filtering out the output

voltage ripple inherent to dc/dc switching

conversions, maximum system performance is

ensured in sensitive instrumentation, test-and-

measurement, audio, and RF applications.

•

Available in High Thermal Performance

Package:

–

5-mm × 5-mm QFN

Operating Temperature Range:

–40°C to +125°C

For applications where positive and negative low-

noise rails are required, consider TI's TPS7A33 family

of negative high-voltage, ultralow-noise linear

regulators.

APPLICATIONS

•

Voltage-Controlled Oscillators (VCO)

Frequency Synthesizers

RF LDO

Test and Measurement Applications

Medical Applications

RX, TX, and PA Circuitry

Supply Rails for Operational Amplifiers,

DACs, ADCs, and Other High-Precision Analog

Circuitry

•

Audio Applications

Post DC/DC Converter Regulation and

Ripple Filtering

•

Industrial Instrumentation

Base Stations and Telecom Infrastructure

+12-V and +24-V Industrial Buses
