Product details
Overview
TLV70212QDBVRQ1 from Texas Instruments is an automotive-grade, 300-mA, low-quiescent-current LDO linear regulator with fixed 1.2 V output, 35 µA IQ, 2% output accuracy over –40°C to +125°C, and 260 mV dropout at 300 mA - used for powering image sensor rails and microprocessor I/O in automotive camera modules.
For engineers reviewing the TLV70212QDBVRQ1 datasheet, TLV70212QDBVRQ1 pinout, TLV70212QDBVRQ1 application, or TLV70212QDBVRQ1 equivalent, key selection considerations include AEC-Q100 Grade 1 qualification, 0.1 µF minimum stable output capacitance, thermal shutdown/overcurrent protection, and SOT-23-5 (DBV) package compatibility with space-constrained automotive PCB layouts.
Technical Context
The TLV70212QDBVRQ1 employs a PMOS pass transistor architecture enabling ultra-low dropout voltage scaling with load current and maintaining regulation down to VIN = VOUT + VDO. Its precision bandgap reference and error amplifier deliver 2% DC accuracy across temperature and line/load conditions.
It integrates active-high enable logic (VEN(H) ≥ 0.9 V), undervoltage lockout (UVLO at 1.9 V), and internal current limiting (320–860 mA). Stability is ensured with ≥0.1 µF effective ceramic output capacitance, supporting compact, bias-voltage-derated capacitors in high-density automotive designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2 V ±2% over –40°C to +125°C - ensures stable core voltage for low-power MCUs and image sensor analog blocks. |
| Max Output Current | 300 mA continuous - supports dual-rail power delivery for CMOS image sensors with burst-mode pixel readout. |
| Quiescent Current | 35 µA typical at zero load - enables always-on operation in automotive body electronics without battery drain. |
| Dropout Voltage | 260 mV at 300 mA - allows operation from 1.46 V input, extending usable range of partially discharged 12-V battery-derived rails. |
| PSRR | 68 dB at 1 kHz - suppresses switching noise from upstream DC/DC converters feeding camera module power trees. |
| Output Noise | 48 µVRMS (100 Hz–100 kHz) - minimizes jitter and SNR degradation in high-resolution image sensor ADC front-ends. |
| Enable Threshold | VEN(H) ≥ 0.9 V, VEN(L) ≤ 0.4 V - compatible with 1.8-V and 3.3-V logic-level microcontrollers for sequenced power-up control. |
Pinout & Package
TLV70212QDBVRQ1 is packaged in a 5-pin SOT-23 (DBV) case measuring 2.90 mm × 1.60 mm × 1.45 mm, optimized for automated placement and thermal performance on 2-layer automotive PCBs.
| 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 return path for IN, OUT, and EN; must connect directly to low-impedance ground plane. |
| EN (Pin 3) | Active-high enable control | Drives regulator ON when ≥0.9 V; reduces ground current to 400 nA in shutdown - enables system-level power gating. |
| NC (Pin 4) | No-connect terminal | Internally unconnected; tie to GND to improve thermal dissipation in high-power-density layouts. |
| OUT (Pin 5) | Regulated output | Delivers 1.2 V ±2%; requires ≥0.1 µF ceramic capacitor to GND - stable with X5R/X7R dielectrics under bias/temperature derating. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation - meets functional safety requirements for ASIL-B camera systems. |

| Thermal shutdown & current limit | Shuts down at ~165°C junction temp; restarts at ~145°C - protects against sustained overload during ECU boot or sensor initialization faults. |
| High PSRR (68 dB @ 1 kHz) | Rejects ripple from buck converters powering adjacent RF/analog sections - preserves signal integrity in multi-rail camera SoMs. |
| Low-noise 48 µVRMS output | Minimizes clock jitter and quantization noise in image sensor analog signal chains - critical for >12-bit dynamic range applications. |
Applications
| Automotive Camera Modules | Image Sensor Power |
|---|---|
Use Scenario: Front-facing ADAS camera with rolling-shutter CMOS sensor requiring clean, sequenced 1.2-V core rail. IC Role / Device Role / Timing Role: Primary LDO supplying sensor digital core and PLL voltage domain; enabled synchronously with MCU GPIO after power-on reset. Use Value: 35 µA quiescent current prevents parasitic battery drain during vehicle sleep mode; 2% accuracy maintains sensor timing margin across temperature. |
Use Scenario: Rear-view camera PCB with space-constrained layout and shared 3.3-V intermediate rail. IC Role / Device Role / Timing Role: Local point-of-load regulator converting 3.3 V to 1.2 V for image sensor I/O interface and ADC reference buffer. Use Value: 0.1 µF stable output capacitance allows 0402 ceramic placement adjacent to sensor - eliminates routing inductance that degrades PSRR. |
| Microprocessor Rails | Automotive Infotainment Head Units |
Use Scenario: Low-power automotive MCU (e.g., TI TDA3xx) requiring isolated 1.2-V core supply independent of main SoC domain. IC Role / Device Role / Timing Role: Secondary LDO providing regulated core voltage during MCU deep-sleep states where main PMIC is disabled. Use Value: 260 mV dropout enables operation from weak 1.46-V input - extends functional uptime during cold-crank battery sag events. |
Use Scenario: In-dash infotainment unit with multiple display interfaces (LVDS, MIPI DSI) sharing a common 1.2-V auxiliary rail. IC Role / Device Role / Timing Role: High-PSRR LDO decoupling noise from display timing controllers and video processors. Use Value: 68 dB PSRR at 1 kHz suppresses switching noise from display backlight boost converters - prevents visible banding artifacts on LCD panels. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV70212QDCKRQ1 | Same electrical specs; uses 5-pin SC70 (DCK) package (2.0 mm × 1.25 mm), 0.3 mm thinner than DBV. | Better suited for ultra-thin camera modules where height < 1.1 mm is mandatory; lower thermal resistance (RθJA = 262.8°C/W vs 249.2°C/W) but smaller copper pad area. | Select TLV70212QDCKRQ1 only when board height budget is < 1.1 mm and thermal load is ≤150 mA; otherwise TLV70212QDBVRQ1 offers superior thermal margin in SOT-23. |
| TPS7A0512PDBVR | Lower IQ (25 µA), same 1.2 V output, but not AEC-Q100 qualified; RθJA = 290°C/W; no UVLO or thermal cycling hysteresis. | Restricted to non-safety-critical consumer or industrial applications; lacks automotive fault diagnostics and temperature hysteresis for reliable thermal recovery. | Choose TPS7A0512PDBVR only for cost-sensitive, non-automotive designs where AEC-Q100 compliance is unnecessary and thermal load is light (<100 mA). |
Compared with TLV70212QDCKRQ1, TLV70212QDBVRQ1 provides higher thermal robustness in high-current automotive environments; compared with TPS7A0512PDBVR, it delivers certified functional safety features essential for camera-based ADAS systems.

FAQ
What is the maximum input voltage rating for TLV70212QDBVRQ1?
The absolute maximum input voltage for TLV70212QDBVRQ1 is 6.0 V, as specified in the Absolute Maximum Ratings table. Operation above this level 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 TLV70212QDBVRQ1 require an input capacitor?
While TLV70212QDBVRQ1 is stable without an input capacitor, Texas Instruments recommends a 0.1–1 µF low-ESR ceramic capacitor between IN and GND to improve transient response, reduce noise coupling, and counteract reactive source impedances. This is especially critical when the device is located >2 cm from the power source or drives fast-switching loads.
How does the enable pin (EN) function on TLV70212QDBVRQ1?
The EN pin on TLV70212QDBVRQ1 is active-high: the regulator turns on when EN voltage exceeds 0.9 V and enters shutdown mode when EN falls below 0.4 V. In shutdown, ground current drops to 400 nA (typical), making TLV70212QDBVRQ1 suitable for low-power sequencing. If enable functionality is unused, connect EN directly to IN.
Is TLV70212QDBVRQ1 compatible with 0.1 µF output capacitors?
Yes - TLV70212QDBVRQ1 is explicitly designed to be stable with an effective output capacitance of ≥0.1 µF, including derated values under operating bias and temperature. This enables use of compact 0402/0603 X5R/X7R ceramics, reducing board area and cost in space-constrained automotive camera modules.
What protection features are integrated into TLV70212QDBVRQ1?
TLV70212QDBVRQ1 integrates thermal shutdown (trips at ~165°C, resets at ~145°C), output current limiting (320–860 mA), and undervoltage lockout (UVLO activates below 1.9 V). These protections ensure safe operation during fault conditions such as short circuits, excessive ambient temperature, or brownout events in automotive environments.
