TPS7A4700RGWR 1 Features 3 Description

The TPS7A47 is a family of positive voltage (+36 V),

TPS7A4700RGWR 1• Input Voltage Range: +3 V to +36 V

ultralow-noise (4 μVRMS) low-dropout linear regulators

TPS7A4700RGWR • Output Voltage Noise: (LDO) capable of sourcing a 1-A load.

4 μVRMS (10 Hz, 100 kHz)

The TPS7A4700 output voltages are user- • Power-Supply Ripple Rejection: programmable (up to 20.5 V) using a printed circuit

– 82 dB (100 Hz) board (PCB) layout without the need of external

– ≥ 55 dB (10 Hz, 10 MHz) resistors or feed-forward capacitors, thus reducing

overall component count. • Two Output Voltage Modes:

– ANY-OUT™ Version (User-Programmable The TPS7A4701 output voltage can be configured

Output via PCB Layout): with a user-programmable PCB layout (up to 20.5 V),

or adjustable (up to 34 V) with external feedback

– No External Feedback Resistors or Feed- resistors. Forward Capacitors Required

The TPS7A47 is designed with bipolar technology – Output Voltage Range: +1.4 V to +20.5 V

primarily for high-accuracy, high-precision

– Adjustable Version (TPS7A4701 only): instrumentation applications where clean voltage rails

operational amplifiers, analog-to-digital converters

TPS7A4700RGWR • Dropout Voltage: 307 mV at 1 A (ADCs), digital-to-analog converters (DACs), and

ensured in sensitive instrumentation, test-andmeasurement,

audio, and RF applications. 2 Applications

For applications where positive and negative low•

Voltage-Controlled Oscillators (VCO) noise rails are required, consider TI's TPS7A33 family
