XC6221D292GR-G

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

The XC6221D292GR-G is a fixed-output low dropout voltage regulator manufactured by Torex Semiconductor. It provides a stable 2.9 V output with a maximum load current of 200 mA. The device operates within an input voltage range of 1.6 V to 6 V and maintains a typical dropout voltage of 95 mV at full load. Quiescent current is specified at 25 uA, ensuring efficient power management. The unit features a typical power supply rejection ratio (PSRR) of 70 dB and offers line regulation of 0.01 %/V with load regulation of 10 mV. It is housed in a USP-4 surface-mount package and supports an operating temperature range from -40°C to +85°C.

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

Verify the specific suffix GR-G corresponds to the USP-4 package and tape-and-reel or cut-tape availability as listed by authorized distributors. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure input voltage does not exceed the 6 V maximum rating during operation. Check for updated datasheet revisions that may affect electrical characteristics or pinout definitions.

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

Select this component when a fixed 2.9 V rail is required with minimal static power draw. The USP-4 package suits space-constrained designs compared to larger SOT packages. Consider the 200 mA current limit for load requirements; higher currents necessitate alternative models. Verify thermal dissipation capabilities within the target enclosure environment given the 120 mW power dissipation rating.

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

This part belongs to the XC6221 series of high-speed LDO regulators from Torex Semiconductor. The series utilizes P-channel driver FETs for fast response times. The 'D' prefix typically indicates a specific output voltage binning or internal reference configuration within the product family. These regulators are designed for applications demanding low noise and high stability in compact form factors.

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

Direct substitutes include other XC6221 variants with identical 2.9 V output and USP-4 packaging, such as XC6221B292GR-G if pin compatibility and electrical specs align. Cross-reference with XC6221D292MR-G only if SOT-25-5 packaging is acceptable. Verify that any replacement maintains the same 200 mA output current and 25 uA quiescent current specifications.
