Product details

Overview

TLV70230QDBVRQ1 from Texas Instruments is an automotive-grade, 300-mA, low-quiescent-current LDO linear regulator with fixed 3.0 V output, 2% accuracy over –40°C to +125°C, 35 µA IQ, and 220 mV dropout at 300 mA - used for powering image sensors and microprocessor rails in automotive camera modules.

For engineers reviewing the TLV70230QDBVRQ1 datasheet, TLV70230QDBVRQ1 pinout, TLV70230QDBVRQ1 application, or TLV70230QDBVRQ1 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, stability with ≥0.1 µF ceramic output capacitance, thermal shutdown/overcurrent protection, and compatibility with space-constrained SOT-23-5 layouts.

Technical Context

The TLV70230QDBVRQ1 employs a PMOS pass transistor architecture enabling ultra-low dropout voltage scaling with load current, while maintaining high PSRR (68 dB at 1 kHz) and low output noise (48 µV_RMS). Its internal bandgap reference and error amplifier deliver 2% DC output accuracy across temperature and line/load conditions.

Functional modes include normal regulation (VIN > VOUT + VDO), dropout operation (VIN < VOUT + VDO), and protected states: current limit (ICL = 320–860 mA), thermal shutdown (T_SD = 165°C), and undervoltage lockout (UVLO = 1.9 V). Enable logic is active-high with 0.9 V turn-on and 0.4 V shutdown thresholds.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 3.0 V ±2% over –40°C to +125°C ambient - ensures stable core rail for automotive SoCs without external feedback.
Max Output Current	300 mA continuous - supports dual-core image sensor processors and low-power MCU subsystems.
Quiescent Current	35 µA typical - enables always-on functionality in battery-backed ADAS modules with minimal standby drain.
Dropout Voltage	220 mV at 300 mA, 3.0 V output - allows operation from degraded 3.3 V supply rails down to 3.22 V under full load.
PSRR	68 dB at 1 kHz - suppresses switching noise from adjacent DC/DC converters feeding camera sensor analog blocks.
Stability Capacitance	Stable with ≥0.1 µF effective ceramic output capacitance - permits use of small 0402/0603 X5R/X7R caps in tight PCB footprints.
ESD Rating	HBM ±2000 V, CDM ±750 V - meets AEC-Q100 stress requirements for automotive harness-connected modules.

Pinout & Package

TLV70230QDBVRQ1 uses the 5-pin SOT-23-5 (DBV) package, 2.90 mm × 1.60 mm body size, with exposed pad for thermal enhancement. Pin 4 (NC) must be tied to GND to improve thermal dissipation.

Pin/Terminal	Circuit Role	Design Meaning
1 - IN	Input power supply connection	Accepts 2.0–5.5 V input; requires 0.1–1 µF low-ESR ceramic capacitor to GND for transient immunity.
2 - GND	Power ground reference	Single-point ground tie for IN and OUT capacitors; critical for PSRR and noise performance.
3 - EN	Enable control input	Active-high logic: ≥0.9 V enables regulation; ≤0.4 V reduces ground current to 1 µA (shutdown mode).
4 - NC	No-connect terminal	Internally unconnected; must be soldered to GND plane to enhance thermal conduction and reliability.
5 - OUT	Regulated output voltage	Delivers 3.0 V ±2%; requires ≥0.1 µF ceramic capacitor to GND - stable even with bias-derated caps.

Key Features

Feature	Design Value
AEC-Q100 Grade 1	Qualified for –40°C to +125°C ambient operation - suitable for under-hood and cabin-mounted camera ECUs.
Low-noise regulation	48 µV_RMS output noise (100 Hz–100 kHz) - preserves SNR in analog signal chains of CMOS image sensors.
Fast start-up time	100 µs typical from EN assertion to 98% VOUT - enables rapid wake-up in event-triggered vision systems.
Thermal & current protection	Integrated thermal shutdown (165°C trip) and foldback current limit - prevents damage during sustained overload or poor heatsinking.
UVLO circuit	1.9 V input undervoltage lockout - avoids erratic behavior during cold-crank or brownout conditions in 12 V automotive systems.

Equivalent & Alternatives

The following parts are listed as comparable options for similar LDO regulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV70030QDBVRQ1	Higher IQ (120 µA), same 300 mA rating and 2% accuracy; lacks UVLO and has lower PSRR (55 dB @ 1 kHz)	Not qualified for Grade 1 temp range; limited to cabin-only infotainment, not under-hood cameras	Select only if lower cost is prioritized over automotive safety compliance and noise rejection.
TLS850F3BTTV50	Integrated watchdog, enable, reset outputs; higher IQ (60 µA); 500 mA rating; 3.3 V fixed output	Designed for ASIL-B system monitoring; includes fail-safe signaling not present in TLV70230QDBVRQ1	Choose when functional safety features (reset generation, window watchdog) are required alongside regulation.

Compared with TLV70230QDBVRQ1, TLV70030QDBVRQ1 trades AEC-Q100 Grade 1 compliance and PSRR for lower BOM cost, while TLS850F3BTTV50 adds safety monitoring at the expense of pin count and design complexity - neither is pin-compatible, requiring layout revision.

FAQ

What is the maximum input voltage rating for TLV70230QDBVRQ1?

The absolute maximum input voltage for TLV70230QDBVRQ1 is 6.0 V, per the Absolute Maximum Ratings table. Operation above this level risks permanent damage. The recommended operating range is 2.0 V to 5.5 V, ensuring reliable regulation and thermal performance within AEC-Q100 Grade 1 specifications.

Does TLV70230QDBVRQ1 require an input capacitor?

While not strictly required for stability, TLV70230QDBVRQ1 benefits from a 0.1–1 µF low-ESR ceramic capacitor between IN and GND. This improves transient response, reduces input ripple coupling, and mitigates voltage excursions caused by source impedance - especially critical in automotive environments with noisy 12 V-derived supplies.

Can TLV70230QDBVRQ1 operate with a 0.1 µF output capacitor?

Yes - TLV70230QDBVRQ1 is explicitly designed to be stable with an effective output capacitance of ≥0.1 µF, including bias- and temperature-derated values. This enables use of small-footprint 0402/0603 X5R/X7R ceramics, reducing board area versus traditional 1 µF solutions.

What is the shutdown current of TLV70230QDBVRQ1?

In shutdown mode (EN ≤ 0.4 V), TLV70230QDBVRQ1 draws 400 nA typical ground current at VIN = 2 V, rising to 1–2.5 µA across 2–4.5 V input range. This ultra-low shutdown current supports long-term battery retention in always-on automotive vision systems.

Is TLV70230QDBVRQ1 pin-compatible with other TLV702-Q1 variants?

Yes - all TLV702-Q1 devices in the DBV (SOT-23-5) package share identical pinout and footprint, including TLV70230QDBVRQ1, TLV70212QDBVRQ1, and TLV70248QDBVRQ1. Only the fixed output voltage differs; no PCB redesign is needed when changing output voltage variants.
