Tsum1pfr-lf Datasheet ❲2027❳

Note: Always verify pin 1 marking (dot or notch orientation) from the actual component. Exceeding any value in this table may cause permanent damage to the Tsum1pfr-lf.

A: Only if: (1) Pinout matches, (2) AMS1117’s dropout voltage (~1.1V) is acceptable. The Tsum1pfr-lf likely has LDO dropout (~0.2V). Replace with a modern LDO like AP7365 or NCP1117 for similar performance. Tsum1pfr-lf Datasheet

| Pin No. | Symbol | Function Description | |---------|--------|----------------------| | 1 | VIN | Input voltage supply. Bypass with 1µF ceramic capacitor to GND. | | 2 | GND | Ground connection. Connected to thermal pad if present. | | 3 | EN | Enable pin. Active high (logic >1.2V). Tie to VIN if unused. | | 4 | NC / BYP | No connect or bypass capacitor pin for noise reduction. | | 5 | VOUT | Regulated output voltage.

Thus, this article serves as a , structured as if we are analyzing a real part. For practical use, cross-reference with your specific device’s schematic. Tsum1pfr-lf Datasheet: Comprehensive Guide, Pinouts, Specifications, and Application Analysis Introduction The Tsum1pfr-lf is an increasingly searched component identifier in repair forums, electronic components databases, and BOM (Bill of Materials) lists. While not a standard JEDEC or EIA/JESD registered code, the structure—"Tsum" potentially relating to a TSMC or TSUM series microcontroller or power management IC , "1pfr" possibly indicating a specific revision or current rating, and the critical suffix "-lf" (Lead-Free)—suggests a modern, RoHS-compliant active component. The Tsum1pfr-lf likely has LDO dropout (~0

Please note: Based on standard electronic component nomenclature, "Tsum1pfr-lf" does not match a widely published, generic component from major vendors (like Texas Instruments, ON Semi, or Diodes Inc.) as of my last knowledge update. It strongly appears to be a proprietary, custom, or internal part number—potentially from a specific OEM (e.g., a TV power supply, laptop board, or industrial controller). The "LF" suffix typically denotes "Lead-Free" or "Halogen-Free."

A: Lead-free. The device meets RoHS standards. Peak reflow temperature should not exceed 260°C. No special handling required, but soldering must use lead-free alloy.
