XC6221A192MR-G

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

The XC6221A192MR-G is a fixed-output low dropout regulator from Torex Semiconductor, providing a nominal output voltage of 1.90V with standard accuracy (+/- 2% for VOUT > 1.50V). It operates within an input voltage range of 1.6V to 6.0V and delivers a maximum output current of 200mA. The device features a typical dropout voltage of 80mV at 100mA load and maintains a low supply current of 25μA. It includes a CE control pin without an internal pull-down resistor and utilizes SOT-25-5 packaging.

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

Verify the specific package type (SOT-25) and output voltage tolerance against project requirements. Confirm that the absence of an internal CE pull-down resistor aligns with the system's shutdown logic design. Ensure compliance with environmental standards such as RoHS and lead-free specifications before finalizing procurement.

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

Select this component when a stable 1.9V rail is required with minimal quiescent current. The lack of an internal pull-down on the CE pin necessitates external biasing or connection management to prevent undefined states. Verify that the load current does not exceed the 200mA limit and that the input voltage remains within the specified operational range.

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

This part belongs to the XC6221 series of CMOS LDO regulators designed for portable electronics. The 'A' designation indicates the variant lacks an internal CE pull-down resistor and CL auto-discharge function. The '192' suffix specifies the factory-set laser-trimmed output voltage of 1.90V in 0.05V increments.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Other XC6221 variants with different output voltages or package types may serve as functional substitutes if electrical parameters match. Variants ending in B, C, or D differ by the inclusion of CE pull-down resistors or auto-discharge circuits.
