LT1761IS5-1.8#TRPBF

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

The LT1761IS5-1.8#TRPBF is a micropower, low noise, low dropout regulator manufactured by Analog Devices Inc. It provides a fixed regulated output voltage of 1.8V with a maximum output current capability of 100mA. The device operates within an input voltage range of 1.8V to 20V and features a typical dropout voltage of 300mV at full load. Quiescent current is maintained at 20μA during operation and drops below 0.1μA in shutdown mode. The unit includes internal protection against overcurrent, overtemperature, reverse battery conditions, and reverse output current.

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

Verify the specific suffix IS5-1.8 corresponds to the Industrial temperature grade (-40°C to 125°C) and the fixed 1.8V output configuration. Confirm the #TRPBF designation indicates lead-free finish and tape-and-reel packaging. Ensure compatibility with the required 5-lead TSOT-23 footprint and pinout before integration.

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

Select this component when a fixed 1.8V rail is required from inputs up to 20V. The industrial grade ensures reliability across wider temperature ranges compared to commercial variants. Consider the low noise specification if powering RF or precision analog sections. Verify that the 100mA current limit meets peak load demands without triggering thermal shutdown.

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

This part belongs to the LT1761 series of low dropout regulators. The series offers various fixed output voltages and adjustable versions in the compact TSOT-23 package. The 'I' grade denotes industrial operating temperature specifications, while the 'S5' indicates the specific 5-lead plastic TSOT-23 package type used for surface mount applications.
