**LT3060EDC-8#TRPBF: A Comprehensive Technical Overview of the 8V Low-Noise LDO Regulator**

In the realm of power management, achieving clean, stable, and low-noise voltage rails is paramount for the performance of sensitive analog and RF circuits. The **LT3060EDC-8#TRCBF** from Analog Devices represents a pinnacle of low-dropout (LDO) regulator design, engineered specifically to meet these demanding requirements. This article provides a detailed technical examination of this high-performance 8V fixed-output LDO regulator.

The LT3060 series is built upon a core architecture that prioritizes ultra-low noise and high power supply rejection (PSR). The **LT3060EDC-8#TRPBF** variant delivers a fixed, precision 8V output from an input voltage range of 2.7V to 20V. Its standout feature is an incredibly **ultra-low output noise of just 30μVRMS** (10Hz to 100kHz), which is crucial for powering noise-sensitive components like precision analog-to-digital converters (ADCs), digital-to-analog converters (DACs), voltage-controlled oscillators (VCOs), and RF transceivers without degrading their performance.

A key to this low-noise performance is the external bypass capacitor for the reference. A single capacitor connected to the NR/SS (Noise Reduction/Soft-Start) pin **reduces output noise to the 30μVRMS level** and provides programmable soft-start functionality to control inrush current during startup. Furthermore, the regulator exhibits **exceptional power supply rejection (PSR)**, exceeding 70dB at 1kHz and maintaining over 40dB out to 1MHz. This makes it highly effective at filtering out ripple and noise from upstream switching regulators, allowing it to act as a silent, clean post-regulator.

Despite its low-noise focus, the LT3060 does not compromise on other critical parameters. It maintains a **low dropout voltage of typically 300mV at 100mA load**, enhancing efficiency and allowing operation with input voltages very close to the output level. The device can deliver a steady 100mA output current and is protected by internal current limiting and thermal shutdown features, ensuring robust operation under fault conditions.

Housed in a compact 8-lead 2mm x 2mm DFN package, the **LT3060EDC-8#TRPBF is optimized for space-constrained PCB designs**. Its minimal external component count—requiring only input, output, and noise-reduction capacitors—simplifies the design-in process and saves valuable board space. The device operates over a full -40°C to +125°C junction temperature range, making it suitable for industrial, automotive, and communications applications.

**ICGOOFind Summary**: The LT3060EDC-8#TRPBF is a superior 8V fixed-output LDO regulator that sets a high bar for low-noise power delivery. Its combination of ultra-low noise, excellent PSR, low dropout voltage, and a tiny footprint makes it an **indispensable component for designers** striving to achieve the highest possible signal integrity in noise-sensitive systems.
