XC6217B212MR-G

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

The XC6217B212MR-G is a fixed-output low dropout regulator from Torex Semiconductor, providing a nominal output voltage of 2.1 V with a maximum continuous output current of 200 mA. It operates within an input voltage range of 1.6 V to 6.0 V and features a typical dropout voltage of 115 mV at 100 mA load. The device incorporates Green Operation technology, maintaining a supply current of 4.5 uA in power save mode and 25 uA in high speed mode. It offers a ripple rejection rate of 70 dB at 1 kHz and includes internal 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 package marking and date code against the manufacturer's latest production data sheet before integration. Confirm that the input capacitor meets the minimum capacitance requirements for stability under all operating temperature conditions. Ensure the GO pin logic levels are correctly configured for the desired operational mode.

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

Select this variant for applications requiring a precise 2.1 V rail with minimal static power consumption. The B-type designation ensures the inclusion of the output discharge resistor, which is critical for systems requiring rapid output voltage decay upon shutdown. Consider the SOT-25 package thermal characteristics relative to the expected power dissipation in the target enclosure.

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

This component belongs to the XC6217 series of high-speed LDO regulators designed for portable electronics. The series distinguishes itself through the integration of a Green Operation function, allowing dynamic adjustment of supply current to optimize battery life. The B-type specifically adds an auto-discharge feature not present in the A-type variants.
