Product details
Overview
TLV70229QDSERQ1 from Texas Instruments is an automotive-grade, 300-mA, low-quiescent-current LDO linear regulator with fixed 2.9-V output, 2% accuracy over temperature, 35-µA IQ, and 220-mV dropout at 300 mA - used to power image sensor rails and microprocessor I/O in automotive camera modules.
For engineers reviewing the TLV70229QDSERQ1 datasheet, TLV70229QDSERQ1 pinout, TLV70229QDSERQ1 application, or TLV70229QDSERQ1 equivalent, this page delivers verified technical context, package-specific pin mapping, real-world application constraints, and validated alternative options for AEC-Q100-compliant designs.
Technical Context
The TLV70229QDSERQ1 employs a PMOS pass transistor architecture enabling ultra-low dropout (37 mV @ 50 mA) and stable operation with ≥0.1 µF ceramic output capacitance. Its precision bandgap reference and error amplifier deliver 2% DC output accuracy across –40°C to +125°C ambient.
It integrates active-high enable (EN), thermal shutdown (165°C trip), current limiting (≥320 mA), and undervoltage lockout (1.9 V). PSRR reaches 68 dB at 1 kHz, and output noise is 48 µVRMS (100 Hz–100 kHz), supporting noise-sensitive analog and RF loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.9 V ±2% - ensures stable bias for 2.8-V nominal image sensor cores without external feedback. |
| Max Output Current | 300 mA - supports dual-lane MIPI CSI-2 camera sensors and low-power MCU I/O rails. |
| Quiescent Current | 35 µA - enables always-on functionality in automotive body electronics with minimal battery drain. |
| Dropout Voltage | 220 mV @ 300 mA - allows operation from 3.12-V minimum input, compatible with degraded 3.3-V supply rails. |
| PSRR | 68 dB @ 1 kHz - suppresses switching noise from adjacent DC/DC converters in infotainment head units. |
| Operating Temp | –40°C to +125°C ambient - qualified per AEC-Q100 Grade 1 for under-hood and ADAS camera placement. |
| ESD Rating | HBM ±2000 V, CDM ±750 V - meets automotive ESD robustness requirements for production assembly. |
Pinout & Package
TLV70229QDSERQ1 is packaged in a 6-pin WSON (DSE) with 1.5 mm × 1.5 mm body size and wettable flank terminals for automated optical inspection (AOI). Thermal pad on underside requires solder connection to PCB ground plane for optimal RθJB = 281.5°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Input voltage supply | Accepts 2.0–5.5 V; requires 0.1–1 µF ceramic capacitor to GND for transient stability and noise filtering. |
| GND (Pin 2) | Power ground reference | Single-point connection for IN and OUT capacitors; must tie thermal pad to same ground plane. |
| OUT (Pin 3) | Regulated output | Delivers 2.9 V ±2%; stable with ≥0.1 µF effective ceramic capacitance (bias + temp derated). |
| NC (Pin 4) | No connection | Internally unconnected; recommended to solder to GND for improved thermal dissipation. |
| NC (Pin 5) | No connection | Internally unconnected; recommended to solder to GND for improved thermal dissipation. |
| EN (Pin 6) | Enable control input | Active-high logic: >0.9 V enables regulation; <0.4 V reduces ground current to ≤2.5 µA in shutdown. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 (–40°C to +125°C ambient), HBM ±2 kV, CDM ±750 V - certified for safety-critical vision systems. |
| Ultra-low IQ | 35 µA operating current - extends battery life in always-on parking camera modules during vehicle sleep mode. |
| Low-noise regulation | 48 µVRMS output noise (100 Hz–100 kHz) - prevents spurious artifacts in high-resolution CMOS image sensor outputs. |
| Small-output-capacitor stability | Stable with ≥0.1 µF effective output capacitance - enables use of compact 0402/0201 X5R/X7R ceramics in space-constrained camera PCBs. |
| Integrated protection | Thermal shutdown (165°C), current limit (≥320 mA), and UVLO (1.9 V) - eliminates need for external fault management circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV70029QDSERQ1 | Higher IQ (120 µA), same 2.9-V output, identical WSON-6 package - lacks 0.1-µF stability guarantee. | Less suitable for ultra-low-power always-on camera modes due to 3.4× higher quiescent current. | Select TLV70229QDSERQ1 when <50-µA IQ and 0.1-µF capacitor compatibility are mandatory. |
| TLS850F29TAV50 | Integrated watchdog, reset, and window comparator; 2.9-V output; SOIC-8 package - larger footprint, higher cost. | Targets full-system power management (e.g., radar ECU), not discrete sensor biasing. | Choose TLV70229QDSERQ1 for cost-optimized, space-constrained single-rail image sensor applications. |
Compared with TLV70029QDSERQ1, TLV70229QDSERQ1 delivers 3.4× lower IQ and guaranteed 0.1-µF stability - critical for battery-backed camera modules. Against TLS850F29TAV50, it offers 60% smaller footprint and 45% lower BOM cost where system supervision is unnecessary.

FAQ
What is the maximum input voltage rating for TLV70229QDSERQ1?
The absolute maximum input voltage for TLV70229QDSERQ1 is 6.0 V, as specified in the Absolute Maximum Ratings table. Operation above this level risks permanent damage. For reliable long-term performance, TI recommends staying within the Recommended Operating Conditions range of 2.0 V to 5.5 V input voltage.
Does TLV70229QDSERQ1 require an input capacitor?
While TLV70229QDSERQ1 does not require an input capacitor for stability, TI strongly recommends a 0.1–1 µF low-ESR ceramic capacitor between IN and GND. This improves transient response, reduces noise coupling, and mitigates voltage excursions caused by inductive source impedance - especially critical in automotive wiring harness environments.
Can TLV70229QDSERQ1 operate with zero load current?
Yes, TLV70229QDSERQ1 regulates to its specified 2.9 V ±2% accuracy even with no output load. Ground current remains at 35 µA typical under no-load conditions, and the device maintains stability with ≥0.1 µF effective output capacitance - making it suitable for standby and wake-on-event automotive subsystems.
What is the thermal shutdown behavior of TLV70229QDSERQ1?
TLV70229QDSERQ1 activates thermal shutdown at approximately 165°C junction temperature and resets at ~145°C. During sustained overload, it cycles between regulation and shutdown to prevent damage. For reliable operation, TI specifies a maximum junction temperature of 125°C - requiring proper PCB copper area and thermal pad soldering per the DSE package layout guidelines.
Is TLV70229QDSERQ1 pin-compatible with other TLV702-Q1 variants?
Yes, all TLV702-Q1 devices in the WSON-6 (DSE) package share identical pinout and footprint, including TLV70229QDSERQ1. This allows drop-in replacement across output voltages (1.2 V to 4.8 V) without PCB redesign - provided input/output capacitor values and layout meet the specific variant's stability and transient requirements.
