XC6217A172NR-G

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

The XC6217A172NR-G is a fixed-output low dropout regulator from Torex Semiconductor, providing a nominal output voltage of 1.7V with a maximum continuous output current of 200mA. It operates within an input voltage range of 1.6V to 6.0V and features a typical dropout voltage of 80mV at 100mA load. The device incorporates Green Operation (GO) technology for automatic switching between high-speed and power-save modes, achieving a standby current of 0.01μA. It utilizes the SSOT-24 package and maintains stability with low ESR ceramic capacitors.

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

Verify the specific suffix NR-G corresponds to the SSOT-24 package configuration required for your design. Confirm that the A-type designation matches the need for a GO pin control interface rather than the C/D types which lack this pin. Ensure compliance with RoHS standards by checking the -G suffix documentation. Validate thermal dissipation requirements against the 150mW power rating in the selected enclosure.

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

Select this component when a fixed 1.7V rail is required with minimal quiescent current draw during light loads. The A-type variant is suitable for designs requiring external mode selection via the GO pin. Verify that the application load profile stays within the 200mA limit and that the input voltage remains above the minimum threshold of 1.6V. Consider the SSOT-24 footprint constraints during PCB layout planning.

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

This part belongs to the XC6217 series of 200mA High Speed Green Operation LDOs fabricated using CMOS process. The series offers precise output voltages selectable in 0.05V increments. The A-type specifically includes a GO pin for mode control but lacks the internal CL discharge resistor found in B-types. It is designed for portable electronics requiring efficient power management.

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

How does the Green Operation function affect performance?

The Green Operation function automatically switches between High-Speed mode for heavy loads and Power-Save mode for light loads, optimizing efficiency and reducing supply current.

What is the purpose of the GO pin on the A-type?

The GO pin allows the user to fix the operation in High-Speed mode by applying a high-level signal, overriding the automatic Green Operation switching behavior.
