Detailed Description

3.0 V fixed-output low-dropout linear regulator in a 5-ball DSBGA package, delivers up to 150 mA with only 0.1 V max dropout at full load. Wide input up to 6 V, enable control, solid PSRR, and full protection set. Ultra-small wafer-level package for dense, battery-powered designs.

Key Features

Fixed 3.0 V output

Output current up to 150 mA

Very low dropout 0.1 V max at 150 mA

Wide input voltage up to 6 V

Positive regulator with single channel

Enable pin for shutdown control

PSRR 50 dB at 1 kHz, 40 dB at 10 kHz

Protections: overcurrent, thermal shutdown, short-circuit

Operating temperature range −40°C to +125°C

RoHS3 compliant

Surface-mount wafer-level package for minimum footprint

Base product family LP3985

Key Advantages

High efficiency at the point of load thanks to low dropout at full current

Tiny 5-ball DSBGA saves board space in wearables and compact modules

Clean 3.0 V rail with useful PSRR for MCUs, sensors, and radios

Robust reliability with full protection suite

Simple design-in: fixed output, minimal external components

Works from a broad range of sources up to 6 V input

Packaging

Type: 5-ball DSBGA wafer-level chip-scale package, tape and reel

Material: wafer-level die with solder balls, no molded body

Size: 1.41 mm x 1.08 mm nominal footprint (very thin profile)

Pin configuration: 5-ball array, WFBGA/DSBGA style; orientation dot for Ball A1; check datasheet for ball map and enable/output/input pin locations

Mounting: surface-mount, lead-free balls

Thermal characteristics: very small thermal mass; ensure copper pour and thermal vias to manage power dissipation P = (VIN − VOUT) × IOUT; see datasheet thermal data for θJA/derating on your board stack-up

Electrical interconnect: low package inductance suited for fast transient decoupling close to the load

Reel packaging: Tape and Reel (TR) for automated pick-and-place

Compliance: RoHS3

Lifecycle

Status: Active and in production per Texas Instruments public listings; not near discontinuation as of this writing

Family continuity: multiple voltage options exist within the LP3985 family

Datasheet

Y-IC hosts the most authoritative datasheet for this product from Texas Instruments on our product page. We recommend downloading the datasheet here for full electrical characteristics, ball map, thermal data, and application notes.

Additional Electrical Notes

Quiescent current and supply current values in some summaries are often listed in microamps. If you see “150 A” or “250 A” in third-party tables, the intended units are typically µA for this class of LDO. Please verify exact Iq and ISUPPLY in the datasheet.
