XC6221A37ANR-G

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

The XC6221A37ANR-G is a fixed-output low dropout regulator from Torex Semiconductor, providing a nominal output voltage of 3.70V with standard accuracy. It delivers a maximum output current of 200mA within an operating input voltage range of 1.6V to 6.0V. The device features a typical dropout voltage of 80mV at 100mA and maintains a low supply current of 25μA. It includes a CE control pin for active-high enable functionality and operates reliably across an ambient temperature range of -40℃ to +85℃.

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

• Integrates a high-speed CMOS architecture with internal reference voltage source, error amplifier, and phase compensation circuitry.
• Features a fold-back current limiter that functions as both an output current limiter and short-circuit protection mechanism.
• Supports stable operation using low ESR ceramic capacitors for both input and output phase compensation.
• Includes an ON/OFF control function via the CE pin to place the entire circuit into a stand-by state.

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

Verify the specific package type against the ordering suffix NR-G, which corresponds to SSOT-24. Confirm the output voltage designation matches the required 3.70V specification. Ensure environmental compliance requirements align with the Halogen and Antimony-free status indicated by the -G suffix. Cross-reference the manufacturer's datasheet for absolute maximum ratings before integration.

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

Select this component when a fixed 3.70V rail is required with minimal footprint constraints. The SSOT-24 package offers a small surface-mount solution suitable for space-limited designs. Consider the standard accuracy tolerance if precise voltage regulation above 1.50V is sufficient. Verify that the load current does not exceed the 200mA limit under worst-case thermal conditions.

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

This part belongs to the XC6221 series of single LDO voltage regulators designed for portable electronic applications. The series utilizes laser trimming technology to set output voltages in increments. The 'A' designator indicates the absence of an internal pull-down resistor on the CE pin and lacks capacitor auto-discharge capabilities, distinguishing it from B, C, and D variants.
