Detailed Description

Dual-channel, fixed 3.3 V low-dropout (LDO) linear regulator in an ultra-small 8-DSBGA package (1.56 x 1.56 mm). Each channel supports up to 150 mA with low dropout (100 mV at 150 mA), high PSRR (about 60 dB at 1 kHz), and robust protections (over-current, over-temperature, short-circuit). Wide input range up to 6 V, enable control, and RoHS3 compliance. Designed for tight PCB spaces and battery-powered designs needing clean, stable rails.

Key Features

Output: 3.3 V fixed, dual outputs, positive configuration

Channel count: 2 independent LDO regulators

Output current: 150 mA per channel

Dropout: 0.1 V max at 150 mA

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

Input voltage: up to 6 V

Enable control for power gating

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

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

Mounting: surface mount

Package: 8-DSBGA, 1.56 x 1.56 mm footprint

RoHS: ROHS3 compliant

Base product number: LP3986

Output type: fixed

Typical quiescent current: ~130 µA; typical supply current: ~320 µA (datasheet dependent)

Key Advantages

Saves board space with a tiny chip-scale package

Dual rails in one device reduce BOM count and simplify design

High PSRR and low dropout improve noise performance and battery efficiency

Built-in protections boost reliability and fault tolerance

Simple enable pin control for low-power states

Broad input range suits single-cell Li-ion and 5 V systems

Stable performance with small ceramic capacitors (see datasheet guidance)

Packaging

Type: 8-DSBGA / 8-WFBGA chip-scale package

Size: 1.56 mm x 1.56 mm nominal

Pins/Balls: 8-ball grid, compact ball layout

Material: lead-free, RoHS3-compliant solder balls; chip-scale construction

Mounting: surface mount, compatible with automated pick-and-place

Delivery: Tape & Reel (TR) for high-volume assembly

Thermal characteristics: designed for -40°C to +125°C operation; thermal performance depends on PCB copper and layout (consult datasheet for power dissipation guidelines)

Electrical properties: dual LDO, 3.3 V fixed outputs, 150 mA per channel, low dropout, high PSRR, enable, integrated protections

Supplier device package: 8-DSBGA (1.56 x 1.56)

Lifecycle

Status: Generally active in mainstream distribution for TI low-noise dual LDOs

Not nearing discontinuation based on current market data; verify with our team for latest status

Equivalent or alternative options (evaluate pinout, package, and exact specs):

- Texas Instruments LP3992 family (dual low-noise LDO, similar output currents and features; various fixed voltages)

- Microchip MIC5322-3.3 (dual 150 mA LDO, low-noise, small footprint)

- Analog Devices ADP223 family (dual LDO, higher current options; check package compatibility)

- Single-channel near-equivalents if two regulators are acceptable on board: TI TLV702-33, TPS732-33, LP5907-3.3 (use two devices to mimic dual rails)
