Detailed Description

Automotive-grade AEC-Q100 low-dropout (LDO) linear regulator. Fixed 3.3 V output, up to 1 A load current, positive output configuration, enable control, strong PSRR, and robust protections in a tiny 6-WSON 2 x 2 mm package with exposed thermal pad. Ideal for space-constrained, noise-sensitive automotive and industrial rails.

Key Features

Fixed 3.3 V output, single regulator channel

Up to 1 A output current

Low dropout: 160 mV at 1 A (max)

Wide input range: up to 6 V

PSRR: ~53 dB at 1 kHz, ~30 dB at 1 MHz (typ)

Enable pin for simple on/off control

Protection: over-current and over-temperature

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

AEC-Q100 qualified (Automotive series)

RoHS3 compliant

Mounting: surface mount (SMD)

Compact package: 6-WSON (2 x 2 mm) with exposed pad

Key Advantages

Low dropout minimizes heat and improves efficiency on 3.3 V rails

Clean output with strong PSRR helps reduce ripple and noise for analog, RF, and precision sensors

Tiny 2 x 2 mm footprint saves PCB area in dense automotive modules

Robust protections enhance reliability in harsh environments

Enable pin simplifies power sequencing and low-power states

Automotive qualification supports use in safety-critical and long-life applications

Packaging

Type: Tape & Reel (TR) for automated assembly

Package / Case: 6-WSON (2 x 2 mm), also known as 6-WDFN with exposed pad

Material: epoxy molding compound body, copper leadframe; lead-free, RoHS3 compliant

Size: 2.0 mm x 2.0 mm body; low-profile height

Pin configuration: 6 leads plus exposed thermal pad (typical functions include VIN, VOUT, EN, GND, sense/NR or NC; refer to datasheet pinout)

Thermal characteristics: exposed pad significantly improves heat dissipation; solder EP to a solid ground plane with multiple thermal vias for lower thermal resistance

Electrical properties linked to package: low dropout (160 mV @ 1 A), strong PSRR (53 dB at 1 kHz), stable operation across -40°C to +125°C TJ

Supplier Device Package: 6-WSON (2 x 2)

Mounting: surface mount

Lifecycle

Status: Active and widely used in automotive designs; not near discontinuation based on current industry status

Equivalent or alternative models (choose based on required output voltage, current, noise, and input range):

- Same family, different fixed outputs: TPS746xxPQWDRVRQ1 (other fixed voltages in the TPS746-Q1 series)

- Lower current, similar features: TPS745-Q1 (0.5 A, AEC-Q100)

- Higher current, similar class: TPS748-Q1 (up to ~1.5 A, AEC-Q100)

- Cost-focused automotive LDOs: TLV767-Q1 (1 A class), TLV761-Q1 (lower current)

- Legacy automotive options: LM2940, LM2937 (check specs and performance differences)
