Detailed Description

Dual-channel low-dropout (LDO) linear regulator with fixed 3.1 V outputs, up to 150 mA per channel, in an ultra-small 8-DSBGA package. Wide input up to 6 V, high PSRR, enable control, and full protection. Ideal for space-constrained, noise-sensitive systems. RoHS3 compliant. Stock available: 2560 pieces.

Key Features

Dual LDO regulators, two outputs at 3.1 V fixed

Output current 150 mA per regulator

Very low dropout 0.1 V at 150 mA

Input voltage up to 6 V

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

Low quiescent current (typical around 130 µA per datasheet)

Enable control for power savings

Protections include overcurrent, overtemperature, short-circuit

Industrial temperature range -40°C to +125°C

Ultra-small footprint 8-DSBGA 1.56 x 1.56 mm

Positive output configuration, fixed output type

RoHS3 compliant, lead-free balls

Key Advantages

Saves board space with tiny DSBGA package while delivering two regulated rails

Extends battery life with low quiescent current and efficient low dropout

Reduces ripple and noise on sensitive rails with strong PSRR

Improves system safety and reliability with comprehensive protections

Simple power sequencing and shutdown via enable pins

Broad 6 V input capability supports varied sources and post-regulation needs

Packaging

Type: Wafer-level fine-pitch BGA, 8-DSBGA and 8-WFBGA variants

Material: Molded package with lead-free SnAgCu solder balls, RoHS3 compliant

Size: 1.56 mm x 1.56 mm footprint (supplier device package 8-DSBGA 1.56x1.56)

Mounting: Surface mount, tape and reel (TR) for automated assembly

Pin configuration: 8-ball grid, dual regulators with enables (see datasheet for exact ball map)

Thermal characteristics: Designed for -40°C to +125°C operation. Use adequate copper area for heat spreading and derating at high ambient.

Electrical properties: Fixed 3.1 V outputs, 150 mA per channel, max input 6 V, dropout 0.1 V at 150 mA, PSRR 60–50 dB (1 kHz to 10 kHz), low quiescent current (typ ~130 µA), enable control, protections for OC/OT/SC

Compliance: RoHS3 compliant

Handling: Standard tape-and-reel for pick-and-place, lead-free reflow per JEDEC profile
