LM2772SD Equivalent & Substitute Parts Reference

Part Overview

The LM2772SD is a power management integrated circuit (PMIC) manufactured by Texas Instruments, designed as a charge pump switching regulator. It offers a positive fixed output voltage of 1.2V, supports up to 150mA output current, and is housed in a 10-WFDFN Exposed Pad package. Its core function is step-down voltage regulation utilizing charge pump topology, with 1 output channel. The LM2772SD is currently listed as obsolete, making it necessary to identify direct alternatives with matching electrical, mechanical, and regulatory properties for continued production, service, and inventory management.

Substitute Part Grouping Explanation

Substitute relationships are established solely where parts match on all critical electrical and mechanical specifications relevant to charge pump PMICs: input voltage range, output voltage, output current, output configuration, number of outputs, topology, switching frequency, mounting type, package/case, and temperature range. Regulatory fields such as RoHS, MSL, and REACH status must also closely correspond. Only those parts that adhere to these provided parameters are included as equivalent substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection between LM2772SD and LM2772SD/NOPB is determined by product status, compliance, and inventory. The LM2772SD is obsolete and RoHS non-compliant, while LM2772SD/NOPB is active and ROHS3 compliant. Both versions share identical electrical, mechanical, and packaging parameters. For applications requiring ongoing regulatory compliance, use LM2772SD/NOPB. Inventory availability and regulatory status must be considered according to project requirements and organizational compliance mandates.
