Product details
Overview
TLV70212QDSERQ1 from Texas Instruments is an AEC-Q100 Grade 1 qualified automotive LDO linear regulator delivering 1.2 V fixed output at up to 300 mA, with 35 µA quiescent current, 2% output accuracy over –40°C to +125°C, and 37 mV dropout at 50 mA - used in image sensor power rails and microprocessor core supplies.
For engineers reviewing the TLV70212QDSERQ1 datasheet, TLV70212QDSERQ1 pinout, TLV70212QDSERQ1 application, or TLV70212QDSERQ1 equivalent, key selection criteria include automotive-grade thermal shutdown (165°C), ultra-low IQ for always-on domains, PSRR of 68 dB at 1 kHz, and stability with only 0.1 µF effective output capacitance.
Technical Context
The TLV70212QDSERQ1 uses a PMOS pass transistor architecture enabling low dropout voltage and high PSRR. Its precision bandgap reference and error amplifier deliver 2% DC accuracy across temperature and load, while integrated undervoltage lockout (UVLO) ensures startup only above 1.9 V input.
Functional modes include normal regulation, dropout operation (where VOUT = VIN – VDO), and current-limit protection (320–860 mA). Enable logic is active-high with 0.9 V turn-on threshold and 0.4 V shutdown threshold, reducing ground current to 400 nA in shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2 V ±2% over –40°C to +125°C - enables direct powering of low-voltage logic cores without external feedback. |
| Max Output Current | 300 mA continuous - supports single-core MCUs and small image sensors in automotive camera modules. |
| Quiescent Current | 35 µA typical at no load - minimizes standby power loss in battery-backed systems like ADAS domain controllers. |
| Dropout Voltage | 37 mV at 50 mA, 220 mV at 300 mA (VOUT = 2.8 V); for 1.2 V version, VDO ≤ 260 mV at 300 mA - allows operation from weak or aged 3.3 V rails. |
| PSRR | 68 dB at 1 kHz - suppresses switching noise from upstream DC/DC converters feeding camera sensor analog blocks. |
| Output Noise | 48 µVRMS (100 Hz–100 kHz) - meets low-noise requirements for analog pixel readout circuits in CMOS image sensors. |
| Enable Threshold | VEN(HI) = 0.9 V, VEN(LO) = 0.4 V - compatible with 1.2 V GPIOs and supports controlled sequencing with microcontroller wake-up signals. |
Pinout & Package
TLV70212QDSERQ1 is packaged in a 6-pin WSON (DSE) package measuring 1.5 mm × 1.5 mm with 0.5 mm pitch. The exposed thermal pad enhances thermal performance in space-constrained automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Input supply connection | Accepts 2 V to 5.5 V input; requires ≥0.1 µF ceramic capacitor to GND for stability and transient response. |
| GND | Power ground reference | Single-point ground connection for both input and output return paths; ties to thermal pad for improved θJA. |
| EN | Active-high enable control | Pull high ≥0.9 V to activate regulator; pull low ≤0.4 V to reduce ground current to 400 nA - enables system-level power gating. |
| OUT | Regulated output | Delivers stable 1.2 V; requires ≥0.1 µF effective capacitance (bias + temp derated) for guaranteed stability. |
| NC | No-connect terminal | Pins 4 and 5 are unconnected; TI recommends tying to GND to improve thermal dissipation and EMI performance. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation - suitable for under-hood and infotainment head unit applications. |
| Stable with 0.1 µF effective COUT | Enables use of compact, cost-effective X5R/X7R ceramics with high bias derating - reduces BOM count and board area. |
| Thermal shutdown & current limit | Shuts down at 165°C junction; restarts at 145°C - protects against sustained overload without external circuitry. |
| Low-noise, high-PSRR regulation | 48 µVRMS noise + 68 dB PSRR at 1 kHz - preserves signal integrity in analog front-ends of automotive cameras. |
| Ultra-low IQ (35 µA) | Reduces standby current in always-on domains - extends battery life in parking-mode vision 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 |
|---|---|---|---|
| TLV70212QDBVRQ1 | SOT-23-5 package (2.9 mm × 1.6 mm); same electrical specs but higher RθJA (249°C/W vs 321°C/W for WSON). | Better suited for lower-power applications (<150 mA) where PCB area is less constrained than thermal budget. | Select TLV70212QDBVRQ1 when legacy SOT layout reuse is required and thermal margin exceeds 20°C. |
| TPS7A0512PDBVR | Lower IQ (25 µA), smaller 1.2 mm × 1.2 mm X2SON package, but not AEC-Q100 qualified; max IOUT = 200 mA. | Limited to cabin interior applications without under-hood temperature or qualification requirements. | Choose TPS7A0512PDBVR only for non-safety-critical consumer-grade infotainment accessories. |
Compared with TLV70212QDSERQ1, TLV70212QDBVRQ1 offers identical regulation performance in a larger, thermally less efficient package, while TPS7A0512PDBVR trades automotive qualification and output current for lower IQ and smaller footprint - making TLV70212QDSERQ1 the sole option meeting full AEC-Q100 Grade 1 + 300 mA + 1.2 V requirements in WSON.

FAQ
What is the maximum input voltage rating for TLV70212QDSERQ1?
The absolute maximum input voltage for TLV70212QDSERQ1 is 6.0 V, as specified in the Absolute Maximum Ratings table. Operation above this level risks permanent damage. Recommended operating input range is 2.0 V to 5.5 V, ensuring proper regulation and thermal safety across automotive temperature extremes.
Does TLV70212QDSERQ1 require an input capacitor for stability?
No, TLV70212QDSERQ1 does not require an input capacitor for stability, but TI strongly recommends a 0.1 µF to 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 TLV70212QDSERQ1 be used with output capacitors smaller than 1 µF?
Yes - TLV70212QDSERQ1 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 compact, high-voltage-rated X5R/X7R ceramics, reducing PCB area and cost versus traditional 1 µF solutions - confirmed in Section 8.2.2.1 of the datasheet.
What is the thermal shutdown behavior of TLV70212QDSERQ1?
TLV70212QDSERQ1 activates thermal shutdown at approximately 165°C junction temperature and resumes regulation when junction cools to ~145°C. This hysteresis prevents oscillation during overload. Continuous cycling indicates insufficient heatsinking or excessive power dissipation - design must limit TJ to ≤125°C for reliable operation per AEC-Q100 Grade 1 requirements.
Is TLV70212QDSERQ1 pin-compatible with other TLV702-Q1 variants?
TLV70212QDSERQ1 shares the same 6-pin WSON (DSE) pinout and footprint with all TLV702-Q1 variants in the DSE package, including TLV70215QDSERQ1 and TLV70218QDSERQ1. Pin functions (IN, GND, EN, OUT, NC, NC) and recommended layout guidelines are identical - enabling voltage-scaling flexibility within the same PCB design.
