Detailed Description

Dual-channel low-dropout linear regulator, fixed 2.5V outputs, 150 mA per rail, high PSRR, enable control, protection against over-current, over-temperature, and short-circuit, in an ultra-compact 8-ball DSBGA package (1.56 x 1.56 mm). RoHS3 compliant. Base product family: LP3986. Suitable for -40°C to +125°C operation, surface-mount assembly. Inventory available: 2531 units. Tape & Reel.

Key Features

Dual positive LDO regulators (2 outputs)

Fixed output voltage: 2.5V (each rail)

Output current: up to 150 mA per channel

Low dropout: max 100 mV at 150 mA

High PSRR: ~60 dB at 1 kHz, ~50 dB at 10 kHz

Enable pin for simple on/off control

Wide input voltage: up to 6V

Low operating quiescent current: approx 130 µA; max supply current ~320 µA

Integrated protections: over-current, over-temperature, short-circuit

Small footprint 8-DSBGA (1.56 x 1.56 mm), wafer-level BGA

RoHS3 compliant

Surface-mount, industrial temperature range (-40°C to +125°C)

Key Advantages

Saves board space with tiny 8-ball DSBGA while providing two regulated rails

Extends battery life thanks to low dropout and low quiescent current

Clean power for sensitive circuits due to strong PSRR

Robust operation with built-in protections, reducing external components and design risk

Simple system control via enable pin

Broad input range supports battery and adapter-powered designs

Packaging

Type: Tape & Reel for automated pick-and-place

Package/Case: 8-DSBGA, also described as 8-WFBGA/DSBGA

Dimensions: 1.56 mm x 1.56 mm body

Material: Wafer-level BGA (silicon die with solder balls), lead-free, RoHS3 compliant

Pin/Ball configuration: 8 balls total; typical ball assignments include VIN, VOUT1, VOUT2, EN, GND, and bypass/sense connections (refer to datasheet for exact ball map)

Mounting: Surface Mount (SMT)

Thermal characteristics: Very small thermal mass; ensure good copper plane for heat spreading and stable operation across -40°C to +125°C

Electrical properties: Dual 2.5V fixed outputs, 150 mA per channel, max 6V input, ~100 mV dropout at 150 mA, PSRR ~60 dB (1 kHz), ~50 dB (10 kHz), low IQ (~130 µA), protections for OCP/OTP/SC

Lifecycle

Status: Active and widely used; not indicated as nearing discontinuation based on available information

Same-series options: LP3986 family variants with different fixed voltages (e.g., other suffixes providing 1.8V, 3.0V, 3.3V outputs). Contact us to confirm exact suffix codes and availability
