AP2112R5-1.2TR-G1

Diodes Incorporated

AP2112R5-1.2TR-G1 is a Diodes Incorporated AP2112 fixed 1.2 V low-dropout regulator — 600 mA output, CMOS design with enable pin and auto-discharge, 55 µA quiescent current, in SOT-89-5, tape-and-reel packing (TR), -40 to +85 °C. The SOT-89-5 package is the selection point: more copper and power dissipation headroom than the SOT-25 version for the full 600 mA rating without throttling. Selection advice: the R5 code is the SOT-89-5 package — the K code is the smaller SOT-25, so match the full AP2112R5-1.2TR-G1 code for package, voltage and packing. The enable pin with discharge resistor simplifies power sequencing; tie it high only if you never need shutdown. Evidence: Diodes/BCD AP2112 datasheet (ordering table) and distributor listings confirm 600 mA, 1.2 V fixed, SOT-89-5 and reel packing. Match the full AP2112R5-1.2TR-G1 code.
