AP2112M-1.8TR-G1

Diodes Incorporated

AP2112M-1.8TR-G1 is a Diodes Incorporated AP2112 fixed 1.8 V low-dropout regulator — 600 mA output, CMOS design with enable pin and auto-discharge, 55 µA quiescent current, in SO-8, tape-and-reel packing (TR), -40 to +85 °C. The SO-8 package is the selection point: the highest thermal mass of the AP2112 family for the full 600 mA rating with margin in always-on rails. Selection advice: the M code is the SO-8 package — the K code is the smaller SOT-25 and R5 is SOT-89-5, so match the full AP2112M-1.8TR-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, 1.8 V fixed, SO-8 and reel packing. Match the full AP2112M-1.8TR-G1 code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

COMMON QUESTIONS

AP2112M-1.8TR-G1 FAQ

What is the difference between AP2112M-1.8TR-G1 and AP2112K-1.2TR-G1, AP2112K-1.8TRG1, AP2112K-2.5TRG1?

Same Diodes Incorporated die family, different orderable SKUs: AP2112K-1.2TR-G1: Compared with AP2112K-3.3TRG1, this code has a 1.2 V fixed output and SOT25 package. A voltage or package change is not a drop-in replacement without electrical and PCB review.; AP2112K-1.8TRG1: Fixed 1.8 V output; AP2112K-2.5TRG1: Fixed 2.5 V output. The trailing characters of the part number are what you actually buy — AP2112M-1.8TR-G1 designates the SO8 build. Never substitute a near-identical code on assumption; confirm every character against the BOM line.

What operating conditions must AP2112M-1.8TR-G1 be checked against?

For this AP2112 device (SO8), the checks that matter are input/output voltage and current, thermal design at your load, and the package/packing suffix on the ordering code. Confirm all four against the Diodes Incorporated datasheet for your operating point before purchase.

What is the difference between package and packing for AP2112M-1.8TR-G1?

Package and packing answer different questions for AP2112M-1.8TR-G1: the package (SO8) is what gets soldered to your board, while packing is how the parts arrive at your line — reel, tube, tray or cut tape. Lots vary, so name the packing format you need in the RFQ and we confirm it against the offered lot.

How do I request a quotation for AP2112M-1.8TR-G1?

Tell us the full AP2112M-1.8TR-G1 order code, the maker (Diodes Incorporated), how many you need, reel or tray preference and acceptable date codes — one message is enough. Expect our quotation back within 24 hours.
