Product details
Overview
TLV70227QDBVRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified 2.7 V fixed-output LDO linear regulator in 5-pin SOT-23 (DBV) package, delivering up to 300 mA with 35 µA quiescent current, 2% output accuracy over –40°C to +125°C, and 220 mV dropout at full load - used for powering image sensors and microprocessor rails in automotive camera modules.
For engineers reviewing the TLV70227QDBVRQ1 datasheet, TLV70227QDBVRQ1 pinout, TLV70227QDBVRQ1 application, or TLV70227QDBVRQ1 equivalent, key selection criteria include low-IQ operation under light load, stability with ≥0.1 µF ceramic output capacitance, thermal shutdown behavior, and enable-controlled sequencing in safety-critical automotive subsystems.
Technical Context
The TLV70227QDBVRQ1 employs a PMOS pass transistor architecture enabling ultra-low dropout voltage scaling with load current, while maintaining high PSRR (68 dB @ 1 kHz) and low output noise (48 µVRMS). Its internal bandgap reference and error amplifier ensure 2% DC accuracy across temperature and line/load conditions.
Functional modes include normal regulation, dropout operation (where VOUT = VIN – VDO), current limiting (320–860 mA), and thermal shutdown (trip at 165°C, reset at 145°C). Enable logic is active-high with 0.9 V turn-on threshold and 0.4 V shutdown threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.7 V ±2% - ensures stable bias for 2.7 V–tolerant image sensor analog blocks and I/O domains. |
| Max Output Current | 300 mA - supports peak transient loads of automotive camera ISPs without dropout. |
| Quiescent Current | 35 µA - enables always-on functionality in vehicle wake-up circuits with minimal battery drain. |
| Dropout Voltage | 220 mV @ 300 mA - allows operation from 2.92 V input, critical for degraded 3.3 V rail scenarios. |
| PSRR | 68 dB @ 1 kHz - suppresses switching noise from adjacent DC/DC converters feeding camera power trees. |
| Output Noise | 48 µVRMS (100 Hz–100 kHz) - preserves SNR in analog signal chains of CMOS image sensors. |
| Enable Threshold | VEN(HI) = 0.9 V, VEN(LO) = 0.4 V - compatible with 1.8 V/3.3 V GPIO control without level-shifting. |
| Thermal Shutdown | 165°C trip / 145°C reset - provides fail-safe protection during sustained overload or poor PCB thermal design. |
Pinout & Package
TLV70227QDBVRQ1 uses the 5-pin SOT-23 (DBV) package (2.90 mm × 1.60 mm), optimized for space-constrained automotive camera modules. Thermal performance: RθJA = 249.2°C/W, RθJB = 85.9°C/W.
| 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 connection for IN and OUT capacitors; separates VIN and VOUT ground planes per layout guidelines. |
| EN (Pin 3) | Active-high enable control | Drives regulator ON when ≥0.9 V; reduces ground current to 1 µA nominal in shutdown mode. |
| NC (Pin 4) | No-connect terminal | Internally unconnected; tie to GND to improve thermal dissipation via PCB copper area. |
| OUT (Pin 5) | Regulated output | Delivers 2.7 V ±2%; stable with ≥0.1 µF effective output capacitance (bias + temp derated). |
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 sensor reliability requirements. |
| Stability with 0.1 µF COUT | Enables use of small-footprint, low-cost X5R/X7R ceramics - reduces BOM cost and board area vs legacy LDOs requiring ≥1 µF. |
| Low-noise, high-PSRR regulation | 48 µVRMS noise + 68 dB PSRR @ 1 kHz - prevents switching ripple from DC/DC stages from corrupting image sensor analog outputs. |
| Integrated protection suite | Thermal shutdown, current limit (320–860 mA), and UVLO (1.9 V) - eliminates need for external fault management circuitry. |
| Ultra-low IQ in shutdown | 400 nA to 2.5 µA shutdown current - extends battery life in always-monitoring automotive vision systems during sleep mode. |
Applications
| Automotive Camera Module Power | Image Sensor Bias Rail |
|---|---|
Use Scenario: Powers rolling-shutter CMOS image sensors in rear-view and surround-view cameras with strict EMI and noise budgets. IC Role / Device Role / Timing Role: Primary 2.7 V analog supply regulator; provides clean, low-noise bias independent of main SoC rail. Use Value: 48 µVRMS output noise prevents fixed-pattern noise in captured images; 68 dB PSRR rejects noise from nearby buck converters. | Use Scenario: Supplies analog front-end (AFE) and PLL circuits in high-resolution automotive image sensors requiring tight voltage tolerance. IC Role / Device Role / Timing Role: Precision voltage reference source; maintains 2% accuracy across –40°C to +125°C junction temperature range. Use Value: 2% DC accuracy ensures consistent pixel response and color fidelity across full automotive temperature envelope. |
| Microprocessor Core Rail | Automotive Infotainment Head Unit |
Use Scenario: Delivers 2.7 V to low-power MCU cores or DSP peripherals in telematics control units with intermittent activity. IC Role / Device Role / Timing Role: Standby power regulator; enabled only during wake events to minimize quiescent drain. Use Value: 35 µA IQ and 400 nA shutdown current extend battery hold-up time during vehicle ignition-off periods. | Use Scenario: Supplies auxiliary logic and interface circuitry (e.g., LVDS serializers, MIPI D-PHY) in head unit display modules. IC Role / Device Role / Timing Role: Secondary regulated rail; sequenced via EN pin to coordinate power-up with main SoC and display controller. Use Value: Active-high EN with 0.9 V threshold integrates directly with 1.8 V FPGA or ASIC GPIOs - no level shifter required. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV70233QDBVRQ1 | Fixed 3.3 V output; identical package, pinout, and specs otherwise - same 35 µA IQ, 300 mA rating, and AEC-Q100 Grade 1 qualification. | Used where system requires 3.3 V logic rail instead of 2.7 V analog rail - not interchangeable without schematic revision. | Select when target load requires 3.3 V; verify compatibility with downstream voltage tolerances and sequencing timing. |
| TPS78027QDBVRQ1 | Lower IQ (500 nA typical), same 2.7 V output and AEC-Q100 Grade 1, but 200 mA max output and different enable threshold (0.6 V). | Better suited for ultra-low-power always-on monitoring functions (e.g., CAN wake detection), not high-transient camera loads. | Choose for battery-sensitive wake-up circuits; avoid for camera ISP peak loads due to 200 mA limit and reduced PSRR. |
Compared with TLV70233QDBVRQ1, TLV70227QDBVRQ1 delivers precise 2.7 V for analog sensor bias rather than digital logic; versus TPS78027QDBVRQ1, it trades ultra-low shutdown current for higher output capability and better transient response - making it optimal for automotive imaging power delivery.

FAQ
What is the maximum input voltage rating for TLV70227QDBVRQ1?
The absolute maximum input voltage for TLV70227QDBVRQ1 is 6.0 V, as specified in the Absolute Maximum Ratings table. Operation above this voltage risks permanent damage. For reliable continuous operation, the recommended input voltage range is 2.0 V to 5.5 V per the Recommended Operating Conditions section of the datasheet.
Does TLV70227QDBVRQ1 require an input capacitor?
While TLV70227QDBVRQ1 is stable without an input capacitor, TI recommends a 0.1 µF to 1 µF low-ESR ceramic capacitor between IN and GND to improve transient response, reduce noise coupling, and counteract reactive source impedances - especially when the device is located >2 cm from the power source or drives fast-switching loads.
Can TLV70227QDBVRQ1 be used with tantalum output capacitors?
TLV70227QDBVRQ1 is optimized for ceramic capacitors and is guaranteed stable with ≥0.1 µF effective ceramic output capacitance. Tantalum capacitors are not recommended due to higher ESR (typically >1 Ω), which may degrade PSRR and transient response; if used, ESR must remain <200 mΩ and effective capacitance ≥0.1 µF under bias and temperature.
What is the thermal shutdown behavior of TLV70227QDBVRQ1?
TLV70227QDBVRQ1 activates thermal shutdown at approximately 165°C junction temperature and resets at ~145°C. During sustained overload, it cycles between shutdown and regulation. This protects against permanent damage but indicates inadequate thermal design - continuous cycling degrades reliability, so PCB copper area and airflow must keep TJ ≤125°C under worst-case load.
Is TLV70227QDBVRQ1 pin-compatible with other TLV702-Q1 variants?
Yes - all TLV702-Q1 variants in the DBV (SOT-23) package, including TLV70227QDBVRQ1, share identical pin configuration (IN, GND, EN, NC, OUT), footprint, and thermal characteristics. Output voltage is the only functional difference; no PCB changes are needed when substituting between fixed-voltage versions in the same package.
