Product details
Overview
TLV70229QDBVRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified low-dropout (LDO) linear regulator delivering 300 mA output current with 2% output voltage accuracy, 35 µA quiescent current, and 220 mV dropout at full load (300 mA, VOUT = 2.9 V). It operates from –40°C to +125°C ambient and is used in power rails for image sensors and infotainment head units.
For engineers reviewing the TLV70229QDBVRQ1 datasheet, TLV70229QDBVRQ1 pinout, TLV70229QDBVRQ1 application, or TLV70229QDBVRQ1 equivalent, key selection criteria include automotive-grade thermal robustness (165°C shutdown), ultra-low IQ for always-on domains, PSRR of 68 dB at 1 kHz, stability with ≥0.1 µF ceramic output capacitance, and enable-controlled sequencing in camera modules.
Technical Context
The TLV70229QDBVRQ1 employs a PMOS pass transistor architecture enabling low dropout and inherent reverse-voltage protection via its body diode. Its precision bandgap reference and error amplifier deliver 2% DC accuracy across temperature and line/load conditions.
Functional modes include normal regulation (VIN > VOUT + VDO), dropout operation (VIN < VOUT + VDO), and current-limit protection (ICL = 320–860 mA), with integrated thermal shutdown (165°C trip, 145°C reset) and undervoltage lockout (UVLO = 1.9 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.9 V ±2% - tightly regulated rail for 2.8–3.0 V logic or sensor biasing without external feedback. |
| Max Output Current | 300 mA continuous - supports mid-power imaging sensors and microcontroller I/O domains. |
| Quiescent Current | 35 µA - enables >10-year battery life in automotive always-on wake-up circuits. |
| Dropout Voltage | 220 mV at 300 mA - allows operation from 3.11 V input when VOUT = 2.9 V, maximizing battery utilization. |
| PSRR | 68 dB at 1 kHz - suppresses switching noise from upstream DC/DC converters feeding sensitive analog circuitry. |
| Output Noise | 48 µVRMS (100 Hz–100 kHz) - suitable for low-noise analog signal chains in camera ISPs. |
| Enable Threshold | VEN(HI) = 0.9 V, VEN(LO) = 0.4 V - compatible with 1.8 V and 3.3 V GPIOs for precise power sequencing. |
Pinout & Package
TLV70229QDBVRQ1 uses the 5-pin SOT-23 (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 |
|---|---|---|
| IN (Pin 1) | Input supply connection | Accepts 2.0–5.5 V input; requires ≥0.1 µF ceramic capacitor to GND for stability and transient response. |
| GND (Pin 2) | Power ground reference | Single-point ground tie for IN and OUT capacitors; critical for PSRR and noise performance. |
| EN (Pin 3) | Active-high enable control | Drives ON above 0.9 V; reduces ground current to 1 µA in shutdown - enables system-level power gating. |
| NC (Pin 4) | No-connect terminal | Internally unconnected; must be soldered to PCB ground plane to lower θJA and improve thermal margin. |
| OUT (Pin 5) | Regulated output | Delivers stable 2.9 V; stable with ≥0.1 µF effective ceramic capacitance - supports small-footprint, high-bias-capacitors. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation - meets automotive body electronics and ADAS module requirements. |
| Thermal shutdown & current limit | 165°C shutdown with 20°C hysteresis and 320–860 mA current limit - prevents damage during short-circuit or overload faults. |
| Ultra-low noise & high PSRR | 48 µVRMS noise + 68 dB PSRR at 1 kHz - preserves SNR in analog front-ends of automotive cameras. |
| Stable with minimal output capacitance | Guaranteed stability with ≥0.1 µF effective COUT - enables use of 0402/0201 X5R/X7R caps in space-constrained modules. |
| Low dropout with PMOS pass element | 37 mV dropout at 50 mA - maintains regulation even under weak battery conditions in parked-mode systems. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV70029QDBVRQ1 | Higher IQ (120 µA), same 2.9 V output and 300 mA rating; lacks 0.1 µF stability guarantee. | Suitable for non-always-on subsystems where noise and ultra-low IQ are less critical. | Choose TLV70229QDBVRQ1 when <50 µA IQ and 0.1 µF COUT support are mandatory. |
| TLS850F2ELVSA1 | Integrated watchdog, higher current (500 mA), wider input (3–40 V); IQ = 40 µA. | Targeted at system power management ICs with supervision, not pure LDO replacement. | Choose TLV70229QDBVRQ1 for discrete, low-noise, low-IQ point-of-load regulation without supervision overhead. |
Compared with TLV70029QDBVRQ1 and TLS850F2ELVSA1, TLV70229QDBVRQ1 uniquely balances ultra-low IQ (35 µA), 0.1 µF stability, and automotive Grade 1 qualification - making it optimal for space- and power-constrained camera and sensor rails where noise and standby current dominate design trade-offs.

FAQ
What is the output voltage tolerance of TLV70229QDBVRQ1 over temperature and load?
The TLV70229QDBVRQ1 maintains ±2% output voltage accuracy across the full AEC-Q100 Grade 1 temperature range (–40°C to +125°C ambient), at all loads from 0 to 300 mA and input voltages from 2.0 V to 5.5 V. This specification is guaranteed in production testing and confirmed in the Electrical Characteristics table of the SLVSC35D datasheet.
Can TLV70229QDBVRQ1 operate with a 0.1 µF output capacitor?
Yes, TLV70229QDBVRQ1 is explicitly designed to be stable with an effective output capacitance of ≥0.1 µF, as stated in the datasheet's Features and Application Information sections. This applies to ceramic capacitors (X5R/X7R) derated for bias and temperature - enabling compact, cost-effective designs in automotive camera modules.
What is the maximum junction temperature and thermal protection behavior of TLV70229QDBVRQ1?
TLV70229QDBVRQ1 triggers thermal shutdown at TJ ≈ 165°C and resets at ≈145°C. Its RθJA is 249.2°C/W in the DBV package. For reliable operation, TI recommends limiting steady-state junction temperature to ≤125°C using appropriate PCB copper area and thermal vias - verified in the Thermal Information section of SLVSC35D.
Does TLV70229QDBVRQ1 support reverse-voltage protection?
TLV70229QDBVRQ1 incorporates a PMOS pass transistor with an intrinsic body diode that conducts when VOUT > VIN. While this provides passive reverse-current path, the diode is not current-limited. TI advises externally limiting reverse current to ≤5% of rated IOUT (≤15 mA) if sustained reverse voltage is expected - per Section 7.3.1 of SLVSC35D.
How does the enable pin (EN) function on TLV70229QDBVRQ1?
The EN pin on TLV70229QDBVRQ1 is active-high: the device regulates when EN ≥ 0.9 V and enters shutdown (IQ ≈ 1 µA) when EN ≤ 0.4 V. If enable functionality is unused, TI recommends connecting EN directly to IN. The EN pin draws only 0.04 µA typical current - confirmed in the Electrical Characteristics table of SLVSC35D.
