Key Features
- Fixed 5V output at 500mA with only 300mV typical dropout voltage, allowing the regulator to stay in regulation from input supplies as low as 5.3V
- Ultra-low output noise performance makes it ideal for noise-sensitive analog, RF, and precision mixed-signal circuit power rails
- Wide 1.8V to 20V input range in a compact 8-pin SOIC package accommodates a broad range of supply architectures from automotive to portable electronics
Applications
The LT1763IS8-5#TRPBF is suited for powering noise-sensitive analog and RF circuitry in handheld instruments, communications modules, and data acquisition systems where a clean, stable 5V rail is required. Its 300mV dropout enables efficient post-regulation from a 6V or 7V intermediate bus, reducing heat dissipation compared with higher-dropout alternatives. The wide input range up to 20V also makes it useful in industrial and automotive accessory designs where supply voltages can vary significantly.

Frequently Asked Questions
What is the dropout voltage of the LT1763IS8-5#TRPBF, and how does this affect minimum input supply requirements?
The LT1763IS8-5#TRPBF has a typical dropout voltage of 300mV and a maximum of 450mV at full 500mA load. For a fixed 5V output, this means the input supply must be at least 5.3V (typical) to 5.45V (worst case) to keep the regulator in regulation. This low dropout allows efficient use of a 6V or 7.2V supply rail common in industrial and battery-backed systems without requiring a higher-voltage input stage.
What input voltage range does the LT1763IS8-5#TRPBF accept, and which supply architectures benefit from this wide range?
The LT1763IS8-5#TRPBF accepts input voltages from 1.8V minimum to 20V maximum absolute. This wide range is beneficial in automotive accessories operating from a 12V to 14.4V vehicle battery, industrial equipment using unregulated 12V or 15V DC bus rails, and multi-supply embedded systems where the upstream regulator output can vary. A single LT1763IS8-5 design can cover all these architectures without component changes.
Why is the LT1763IS8-5#TRPBF preferred over a standard LDO for powering precision analog circuits?
Standard LDO regulators often exhibit output noise levels of 100µV RMS or more, which can degrade the SNR of 16-bit or 24-bit ADCs and sensitive RF front-ends. The LT1763 series is specifically designed for low-noise output, with spectral noise density optimized for analog supply applications. Powering an ADC reference or an op-amp supply from a low-noise LDO like the LT1763IS8-5 rather than a switching regulator or noisy linear regulator can improve measurement accuracy by 10dB or more in high-resolution acquisition systems.
What package does the LT1763IS8-5#TRPBF come in, and how does this affect thermal management at 500mA output current?
The LT1763IS8-5#TRPBF is housed in an 8-pin SOIC package. At 500mA with a 10V input to 5V output, the device dissipates 2.5W, which exceeds what a standard SOIC-8 can handle without thermal management. Designers must use a PCB copper pour or thermal relief pad under the package and derate output current at elevated ambient temperatures above 25°C to keep the junction below 125°C and maintain reliable long-term operation.
