LT1129CS8-5#TRPBF

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The LT1129CS8-5#TRPBF is a micropower low dropout regulator with shutdown, manufactured by Analog Devices Inc. It provides a fixed 5V output and supports up to 700mA of load current. The device operates within an input voltage range of 3.8V to 20V and maintains a typical dropout voltage of 400mV at maximum output. Quiescent current is 50μA during operation and reduces to 16μA in shutdown mode. It functions reliably across a temperature range of 0°C to 125°C and utilizes an 8-lead plastic SOIC package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

Integrated shutdown control for extended battery life
Reverse input protection without external diodes
Stable with small ceramic or tantalum output capacitors
Thermal limiting for overload protection

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Applications

Battery-powered systems
Post-regulator for switching supplies
5V to 3.3V logic level translation
Backup power circuits

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the C-grade designation aligns with the required 0°C to 125°C operating temperature range for your application environment. Ensure compatibility with the 8-lead SOIC footprint during PCB layout review.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component for designs requiring low quiescent current and reverse input tolerance. The fixed 5V output simplifies biasing compared to adjustable variants. Consider thermal resistance characteristics of the SOIC package if high ambient temperatures or continuous heavy loads are expected.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the LT1129 family of micropower LDO regulators. It shares architectural similarities with the LT1129-3.3 and standard adjustable LT1129 models. The primary distinction lies in the internal resistor network setting the output voltage to 5V rather than 3.3V or an adjustable range.
