Detailed Description

Dual low-dropout (LDO) linear regulator with fixed outputs at 2.8V and 1.8V, up to 150 mA per regulator

Ultra-compact 8-ball DSBGA package, 1.56 x 1.56 mm footprint, surface mount

Wide input range up to 6V, positive output configuration

Enable control for simple on/off power management

Robust protection: over-current, over-temperature, and short-circuit

RoHS3 compliant, NOPB (lead-free) finishing

Main Category: Integrated Circuits (ICs) | Small Classification: PMIC – Voltage Regulators – Linear, LDO Regulators

Base Product Number: LP3986

Stock available: 2517 pieces (Tape & Reel)

Key Features

Two fixed output rails: 2.8V and 1.8V

Output current: up to 150 mA per regulator

Low dropout: 0.1V at 150 mA (typical operating point)

Input voltage: up to 6V

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

Quiescent current: about 130 µA typical

Supply current: up to about 320 µA max

Enable pin for power sequencing and low standby power

Operating temperature: -40°C to +125°C (industrial grade)

Surface-mount DSBGA for smallest footprint designs

Positive output configuration

Short-circuit, over-current, and thermal shutdown protection

Key Advantages

Saves board space with ultra-small 8-ball DSBGA (1.56 x 1.56 mm)

Supports common dual rails (2.8V analog/I/O and 1.8V core) for modern MCUs, RF, and sensors

Low dropout at full load helps extend battery life

Good PSRR improves supply cleanliness for sensitive analog/RF blocks

Simple design-in with fixed voltages and enable control

Industrial temperature range for reliable operation in harsh environments

Low quiescent current helps minimize standby drain

Packaging

Type: 8-ball DSBGA (wafer-level chip-scale BGA), supplier device package 8-DSBGA

Material: silicon die with lead-free solder balls (NOPB), designed for RoHS3 compliance

Size: 1.56 mm x 1.56 mm body, ultra-low profile

Pin configuration: 8-ball array; ball map defined in the datasheet for VIN, VOUT1, VOUT2, GND, EN, and internal nodes

Mounting: surface mount; follow TI reflow profile for WLCSP/DSBGA

Thermal characteristics: thermal performance depends on PCB copper area and layout; use solid ground planes and thermal vias to improve heat spreading

Electrical properties: dual fixed LDO outputs (2.8V and 1.8V), up to 150 mA each; max VIN 6V; dropout ~100 mV at 150 mA; PSRR ~60 dB @ 1 kHz; protections include OCP/OTP/short-circuit

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

Lifecycle

Current status: Generally active in production; no end-of-life notice known at this time

Not nearing discontinuation based on current information; confirm with Y-IC for latest lifecycle updates

Equivalent or alternative models (selection depends on required voltages, noise, current, and footprint)

TI LP3986 family variants (LP3986TL-xxxx/NOPB) with other fixed voltage pairs; typically pin-compatible within the DSBGA family

TI TLV702xx dual LDO (higher current options; different packages, not pin-compatible)

TI TLV704xx dual LDO (low IQ options; different packages, not pin-compatible)

TI TPS7A05 single LDO (low-noise, 200 mA; use two for dual-rail replacement; not pin-compatible)

TI TPS7A24 single LDO (low IQ, wide VIN; use two for dual-rail replacement; not pin-compatible)
