Detailed Description

LP3986TLX-2818 is a dual, low-noise, high-PSRR, low-dropout (LDO) linear regulator in a tiny micro SMD/DSBGA package. The “2818” code indicates factory-set outputs of 2.8 V and 1.8 V. It is designed for noise‑sensitive, space‑constrained portable electronics. It uses few external parts, supports small ceramic capacitors, and includes protection features for robust operation.

Key Features

Dual fixed-output LDO rails: 2.8 V and 1.8 V (code 2818)

Low dropout for better battery life

High PSRR for clean power to RF/analog circuits

Low output noise; suitable for sensitive blocks

Very low quiescent current; very low shutdown current

Fast transient response; soft-start behavior

Current limit and thermal shutdown protections

Small external capacitors (ceramic) for stability

Tiny DSBGA/micro SMD footprint for dense layouts

Enable control (variant dependent) for power sequencing

Key Advantages

Two clean rails in one chip reduce footprint and BOM

Stable, low-noise outputs improve RF, audio, and sensor performance

Battery-friendly operation extends runtime

Built-in protections improve system reliability

Ideal for handheld and wearable designs with tight space

Packaging

Package type: Micro SMD / DSBGA (TI TLX family), customer noted as 2520BGA; case code provided as 4850

Body size: approximately 2.5 mm × 2.0 mm class (refer to the mechanical drawing in the datasheet for exact X/Y/Z dimensions and tolerances)

Bump configuration: fine‑pitch micro ball grid array; dedicated bumps for VIN, VOUT1 (2.8 V), VOUT2 (1.8 V), grounds, and control pins (see datasheet bump map and pin functions)

Materials and finish: lead‑free, RoHS‑compliant SnAgCu solder bumps; organic mold compound body

Mounting: surface mount; reflow compatible; observe device MSL handling on the label

Thermal characteristics: heat is dissipated primarily through PCB copper; use adequate copper area and thermal vias; consult datasheet for θJA/θJC guidance and recommended PCB layout for best thermal performance

Electrical interface and stability: designed to be stable with small ceramic input/output capacitors; follow datasheet ESR and capacitance requirements; verify start‑up and load transient behavior with your exact capacitor selection

Shipping: tape‑and‑reel for automated placement; “TLX” orderable code commonly indicates reel packaging (confirm reel width and quantity on the datasheet/orderable table)

Lifecycle

Status: Mature Texas Instruments device (originated from National Semiconductor). Not indicated as near end‑of‑life in public sources at the time of writing, but availability can vary by voltage option and package.

Alternatives and comparable TI families (verify specs, footprint, and pinout; not guaranteed drop‑in):

- LP3992 dual LDO family (similar concept; different options and pinout)

- LP3985 single LDO family (if only one rail is needed)

- TPS7A20/TPS7A21 low‑noise single LDOs (modern, very low Iq options)

- TLV702/TLV704 families (cost‑effective, low‑Iq LDOs; single/dual options)

- TPS7A26 dual LDO family (where available; check voltage options and package)
