Overview
The LT1766EGN-5#TR is a micropower low-dropout (LDO) linear regulator manufactured by Linear Technology, now part of Analog Devices. It provides a fixed 5V output with a maximum load current of 100mA. The device operates from an input voltage range of 2.7V to 20V and features a typical quiescent current of 35µA. It is housed in a 16-pin SSOP package and is designed for battery-powered applications requiring high efficiency and low noise performance.
Feature Summary
- Micropower operation with ultra-low quiescent current to extend battery life
- Low-noise LDO architecture suitable for sensitive analog circuits
- Fixed 5V output option ensuring stable voltage regulation
- Wide input voltage range supporting various power supply configurations
Applications
- Battery-powered portable electronic devices
- RF and communication modules requiring clean power supplies
- Microcontroller system voltage regulation
- Sensor interface circuits demanding low noise
Procurement Notes
Verify the manufacturer designation as Analog Devices Inc., reflecting the acquisition of Linear Technology. Confirm the specific suffix #TRPBF indicates tape-and-reel packaging and RoHS compliance. Ensure the order matches the exact pinout and thermal characteristics required for the target PCB layout.
Selection Notes
Select this component when a fixed 5V output is required with minimal static power consumption. It is appropriate for designs where input voltages vary significantly above the output level. Consider the thermal dissipation capabilities of the SSOP package under full load conditions relative to ambient temperature constraints.
Part Context
This part belongs to the LT1766 family of micropower LDO regulators. These devices are engineered for applications prioritizing energy efficiency without compromising output stability. The family includes various fixed voltage options and adjustable versions, all sharing similar low-noise and low-quiescent-current characteristics.
Replacement Considerations
Check for direct equivalents such as the LT1766ES5-5#PBF if leaded packaging is acceptable instead of surface mount. Verify compatibility with other micropower LDOs offering 100mA output and 5V fixed regulation, ensuring pin-to-pin compatibility and matching electrical specifications.
