XC6705B311GR-G

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

The XC6705B311GR-G is a positive fixed linear voltage regulator from Torex Semiconductor, designed for high-speed operation with low quiescent current. It provides a fixed output voltage of 3.1 V with a maximum output current of 200 mA. The device operates within an input voltage range of 1.6 V to 20 V and features a typical power supply rejection ratio (PSRR) of 70 dB at 1 kHz. It maintains a low dropout voltage of 200 mV at full load. The component supports surface-mount installation in a USP-4 package and functions reliably across an operating temperature range of -40°C to +85°C.

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

Verify the specific suffix GR-G against official Torex documentation to confirm package type and tape/reel specifications. Ensure compatibility with your PCB footprint for the USP-4 package. Cross-reference the 3.1 V output tolerance and thermal performance requirements with your system design constraints before finalizing procurement decisions.

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

Select this component when a fixed 3.1 V rail is required with minimal static current draw. It is suitable for applications where input voltages vary significantly between 1.6 V and 20 V. Consider the 200 mA current limit and 200 mV dropout voltage for headroom calculations. The USP-4 package is ideal for compact layouts compared to larger LDO options.

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