Detailed Description

Dual low-dropout linear regulator with two fixed outputs: 2.5 V and 1.8 V, 150 mA per rail. Compact 8-ball DSBGA package (approx. 1.56 mm x 1.56 mm). Wide input up to 6 V, low dropout around 100 mV at 150 mA, high PSRR, low quiescent current, enable control, and full protection (overcurrent, overtemperature, short-circuit). RoHS3 compliant. Operating temperature −40°C to 125°C. Base product number LP3986. Supplied in Tape & Reel for automated SMT assembly.

Key Features

Dual LDO regulators in one chip

Fixed outputs: 2.5 V and 1.8 V

Output current: up to 150 mA per channel

Input voltage: up to 6 V

Maximum dropout: about 0.1 V at 150 mA

PSRR: about 60 dB at 1 kHz, about 50 dB at 10 kHz

Low quiescent current around 130 µA typical, supply current up to about 320 µA

Enable pin for easy on/off control

Protection built in: overcurrent, thermal shutdown, short-circuit

Tiny 8-DSBGA package (1.56 mm x 1.56 mm) for space-constrained designs

Wide temperature operation: −40°C to 125°C

RoHS3 compliant, lead-free

Key Advantages

Two clean, regulated rails in one device simplifies your power tree and BOM

High PSRR helps keep noise off sensitive analog, RF, and digital rails

Low dropout allows longer battery life and efficient operation with low headroom

Small footprint frees PCB space in portable and wearable designs

Built-in protections improve reliability and reduce external component count

Enable pin supports power sequencing and low-power modes

Tape & Reel packaging supports high-volume, automated production

Packaging

Shipment type: Tape & Reel (TR) for automated pick-and-place

Device package: 8-DSBGA / 8-WFBGA, approx. 1.56 mm x 1.56 mm body size

Material: Lead-free, RoHS3 compliant

Mounting: Surface-mount technology

Ball/pin configuration: 8-ball array (compact layout); refer to the datasheet for ball map and exact pin functions

Thermal characteristics: Small BGA relies on PCB copper and layout for heat spreading; operates −40°C to 125°C; consult datasheet for thermal impedance and derating

Electrical properties summary: dual fixed positive regulators, 2.5 V and 1.8 V outputs, up to 150 mA each, 6 V max input, ~0.1 V dropout @ 150 mA, high PSRR, low Iq, integrated protections, enable control

Lifecycle

Current status: Active based on the latest available data; not near discontinuation as of our last update

Direct family alternatives (same LP3986 platform, same package/pinout, different fixed voltage pairs): LP3986TL variants with outputs such as 1.8 V/1.8 V, 1.8 V/2.5 V, 1.8 V/3.3 V, 2.5 V/2.5 V, 2.5 V/3.3 V, 3.0 V/3.0 V, 3.3 V/3.3 V (exact MPN suffixes depend on voltage combination)

Comparable dual LDO options to consider for similar use cases: TI TPS720 series (dual LDO), Analog Devices ADP223 (dual LDO), Maxim MAX8887 (dual LDO). Pinouts and specs differ; verify compatibility
