Detailed Description

Ultra-small, fixed 5V low-dropout (LDO) linear regulator in a 5-ball DSBGA package. Delivers up to 150 mA with very low dropout (about 100 mV at full load), good PSRR at audio-band frequencies, and robust protections. Designed for space-constrained, battery-powered systems needing a clean, stable 5V rail.

Key Features

Output voltage: fixed 5V

Output current: up to 150 mA

Very low dropout: 0.1 V max at 150 mA

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

Input voltage: up to 6 V

Control: Enable pin for on/off control

Protections: over-current, over-temperature, short-circuit

One regulator channel

Package: 5-DSBGA (WFBGA/DSBGA), 1.41 mm x 1.08 mm nominal footprint

Mounting: surface mount

Operating temperature: -40°C to +125°C

RoHS: ROHS3 compliant

Base product number: LP3985

Shipment format: Tape & Reel (TR)

Key Advantages

Tiny footprint enables high-density layouts and ultra-compact designs

Low dropout reduces wasted power and improves battery life

Simple design: minimal external components and easy enable control

Solid line regulation and load regulation for stable 5V rails

Built-in protections improve reliability in harsh or variable loads

Wide operating temperature range supports industrial and automotive environments

Packaging

Type: 5-DSBGA (Wafer-Level/Die-Size BGA), also referenced as 5-WFBGA, DSBGA

Material: silicon die with lead-free solder balls; RoHS3 compliant construction

Size: 1.41 mm x 1.08 mm nominal footprint; ultra low-profile

Pin configuration: 5-ball array; refer to the datasheet for the exact ball map and pin functions

Mounting type: surface mount (SMT), suitable for automated assembly

Shipment: Tape & Reel (TR) for high-volume manufacturing

Thermal characteristics: designed for -40°C to +125°C operation; thermal performance depends on PCB copper area and layout; follow datasheet derating and layout guidance for best heat spreading

Electrical properties: fixed 5V output, up to 150 mA load, max input 6 V, typ. quiescent current ~150 µA and max supply current ~250 µA (confirm exact values in the datasheet), dropout 0.1 V at 150 mA, PSRR ~50 dB at 1 kHz, ~40 dB at 10 kHz, integrated enable and comprehensive protections

Lifecycle

Status: Active in Texas Instruments’ portfolio based on the latest available information; not announced as nearing discontinuation
