IXD1209F302MR-G

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

The IXD1209F302MR-G is a high-speed low-dropout linear regulator manufactured by Zilog. It provides an adjustable output voltage of 3.0 V with ±2% accuracy, incrementable in 0.05 V steps across a 0.9 V to 6.0 V range. The device supports up to 300 mA output current and operates within a 2 V to 10 V input voltage window. Key electrical characteristics include a typical standby current below 0.1 µA, 70 dB ripple rejection at 10 kHz, and an operating temperature range from -40°C to +85°C. It utilizes a SOT-25 package.

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

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

Verify the specific suffix 'MR-G' corresponds to the SOT-25 package configuration and RoHS compliance status as defined in the official ordering information. Confirm the CE pin logic matches the Type F designation (Active High, No Pull-down). Ensure the required output voltage tolerance aligns with the ±2% specification provided in the datasheet before finalizing procurement specifications.

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

Select this component when a stable 3.0 V rail is required with a maximum load current of 300 mA. The Type F designation indicates an active-high enable signal without internal pull-down resistors, necessitating external drive or connection to VIN/VSS. Verify that the input voltage remains above the dropout threshold plus headroom requirements for the expected load current to maintain regulation.
