XC6210D29AMR-G

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

The XC6210D29AMR-G is a positive voltage low dropout regulator from Torex Semiconductor, fabricated using CMOS process. It provides a fixed output voltage of 2.9V with an accuracy of ±2%. The device supports a maximum output current exceeding 700mA and operates within an input voltage range of 1.50V to 6.00V. Key electrical characteristics include a typical supply current of 35μA, a ripple rejection rate of 60dB at 1kHz, and a dropout voltage of 50mV at 100mA. It features CE pin control for standby mode operation and includes built-in current limit and short circuit protection.

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

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

Verify the specific ordering suffix 'MR-G' confirms the SOT-25 package format and Halogen/Antimony-free compliance. Ensure the 'D' series designation matches the requirement for Low Active CE logic without pull-up resistors. Confirm the '29' code corresponds to the 2.9V output voltage setting. Cross-reference the datasheet version to ensure all absolute maximum ratings are current.

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

Select this component when a fixed 2.9V output is required with high current capability up to 700mA. The D-series type is appropriate for systems requiring Low Active CE control signals without external pull-up components. Verify that the application load does not exceed the thermal dissipation limits for the SOT-25 package under expected ambient temperatures and input-output differentials.

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

What is the function of the CE pin on the XC6210D29AMR-G?

The CE pin controls the ON/OFF state of the regulator. For the D-series, the device is active when the CE pin is Low and enters standby mode when the CE pin is High or Open.

How does the current limiter operate in this regulator?

The IC features a fixed current limiter and a foldback circuit. When the output current reaches the limit level, the output voltage drops, causing the foldback circuit to further reduce the output current to protect the device.
