Supplier device package PG-TO252-5

Compliance RoHS3 compliant

Lifecycle

Status Active production for automotive OPTIREG family as of current information

Not near discontinuation based on typical availability for Infineon automotive LDOs

Exact quiescent current listed in provided parameters as 220 A and should be verified in the official datasheet; typical values for this class are in the microamp range

True drop‑in equivalents require matching pinout, package, and performance; due to package-specific pin mapping and protections, there may not be a direct 1:1 cross
