Product details
Overview
TLV70225QDSERQ1 from Texas Instruments is an automotive-grade, 2.5 V fixed-output, 300-mA low-dropout (LDO) linear regulator in a 6-pin WSON package. It delivers 2% output voltage accuracy over –40°C to +125°C, features 35 µA quiescent current, 260 mV dropout at 300 mA, and 68 dB PSRR at 1 kHz - enabling reliable power for image sensor rails in automotive camera modules.
For engineers reviewing the TLV70225QDSERQ1 datasheet, TLV70225QDSERQ1 pinout, TLV70225QDSERQ1 application, or TLV70225QDSERQ1 equivalent, key selection considerations include AEC-Q100 Grade 1 qualification, thermal shutdown/overcurrent protection, stability with ≥0.1 µF ceramic output capacitance, and enable-controlled shutdown with 1 µA quiescent current in disabled state.
Technical Context
The TLV70225QDSERQ1 employs a PMOS pass transistor architecture to achieve ultra-low dropout and high PSRR. Its precision bandgap reference and error amplifier maintain ±2% regulation across temperature and load, while integrated UVLO ensures startup only above 1.9 V input.
Functional modes include normal regulation (VIN > VOUT + VDO), dropout operation (VIN < VOUT + VDO), and current-limit protection (IOUT > 320 mA). Thermal shutdown activates at 165°C junction temperature and resets at 145°C, with cycling behavior under sustained overload.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5 V ±2% over –40°C to +125°C - supports stable core supply for 2.5 V logic and analog sensors. |
| Max Output Current | 300 mA continuous - sufficient for powering single CMOS image sensors or microcontroller I/O rails. |
| Dropout Voltage | 260 mV at 300 mA - enables operation from 2.75 V input while maintaining 2.5 V output, critical for battery-sag conditions. |
| Quiescent Current | 35 µA at no load - minimizes standby power in always-on automotive subsystems like ADAS cameras. |
| PSRR | 68 dB at 1 kHz - suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Enable Threshold | EN high = ≥0.9 V; EN low = ≤0.4 V - compatible with standard automotive GPIOs and allows clean sequencing control. |
| Stability Capacitance | Stable with ≥0.1 µF effective ceramic output capacitance - permits use of small, low-cost 0402/0603 X5R/X7R caps in space-constrained modules. |
Pinout & Package
TLV70225QDSERQ1 is housed in a 1.5 mm × 1.5 mm, 6-pin WSON (DSE) package with wettable flanks, optimized for automated optical inspection (AOI) and thermal performance in automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Input voltage supply | Accepts 2.0–5.5 V input; requires 0.1–1 µF low-ESR ceramic capacitor to GND for transient immunity and stability. |
| GND (Pin 2) | Power ground reference | Single-point connection for IN and OUT return paths; must tie NC pins to GND to improve thermal dissipation. |
| EN (Pin 6) | Active-high enable control | Drives regulator ON when ≥0.9 V; reduces ground current to 1 µA nominal when ≤0.4 V - enables system-level power gating. |
| OUT (Pin 3) | Regulated output | Delivers 2.5 V ±2%; requires ≥0.1 µF ceramic cap to GND; output impedance remains low up to 100 kHz for dynamic load support. |
| NC (Pins 4, 5) | No-connect terminals | Internally unconnected; must be tied to GND on PCB to enhance thermal conduction from die to board. |
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 environmental requirements. |
| Ultra-low IQ (35 µA) | Enables >10-year battery life in always-on parking surveillance systems powered by coin cells or backup batteries. |
| High PSRR (68 dB @ 1 kHz) | Rejects ripple from buck converter switching frequencies, preserving signal integrity in analog front-ends of image sensors. |
| Thermal shutdown + current limit | Protects against short-circuit faults and PCB overheating without external circuitry - reduces BOM count and design validation effort. |
| UVLO (1.9 V turn-on) | Prevents erratic startup during cold-cranking or brownout events - ensures deterministic power-up sequence in vehicle ECUs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV70225QDBVRQ1 | Same electrical specs but in 5-pin SOT-23 (DBV) package; 2.9 mm × 1.6 mm footprint vs. WSON's 1.5 mm × 1.5 mm. | Larger thermal resistance (RθJA = 249.2°C/W vs. 321.3°C/W) - less suitable for high-power-density modules with limited airflow. | Select TLV70225QDBVRQ1 only when legacy SOT-23 assembly lines or manual rework constraints prohibit WSON adoption. |
| TPS7A0525PDBVR | Lower IQ (25 µA), same 2.5 V output, but not AEC-Q100 qualified; RθJA = 277°C/W in SOT-23. | Lacks automotive qualification and thermal shutdown hysteresis - unsuitable for safety-critical vision systems per ISO 26262. | Consider TPS7A0525PDBVR only for non-automotive industrial or consumer applications where cost and IQ are prioritized over qualification. |
Compared with TLV70225QDBVRQ1 and TPS7A0525PDBVR, TLV70225QDSERQ1 uniquely combines AEC-Q100 Grade 1 compliance, WSON thermal efficiency, and guaranteed 2% accuracy across full automotive temperature range - making it the only drop-in option for space-constrained, safety-aware camera power designs.

FAQ
What is the maximum input voltage rating for TLV70225QDSERQ1?
The absolute maximum input voltage for TLV70225QDSERQ1 is 6.0 V, as specified in the Absolute Maximum Ratings table. Operation above this level risks permanent damage. For reliable long-term use, the recommended input range is 2.0 V to 5.5 V - ensuring proper regulation, thermal margin, and compatibility with common automotive supply rails including post-boost and pre-LDO stages.
Does TLV70225QDSERQ1 require an input capacitor for stability?
TLV70225QDSERQ1 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 input ripple coupling, and prevents oscillation when source impedance exceeds 2 Ω - especially critical in automotive environments with long harness runs and noisy alternator outputs.
Can TLV70225QDSERQ1 operate with a 0.1 µF output capacitor?
Yes, TLV70225QDSERQ1 is explicitly designed to be stable with an effective output capacitance of ≥0.1 µF, provided the capacitor maintains that value under operating bias voltage and temperature. This enables use of compact 0402/0603 X5R/X7R ceramics - though actual rated capacitance must be derated for DC bias and temperature to ensure ≥0.1 µF effective value at the OUT pin.
What is the shutdown current of TLV70225QDSERQ1 when EN is pulled low?
When EN is held ≤0.4 V, TLV70225QDSERQ1 enters shutdown mode with ground pin current (ISHDN) of 1 µA typical and ≤2.5 µA maximum over 2 V ≤ VIN ≤ 4.5 V. This ultra-low shutdown current preserves battery energy in always-on automotive vision systems, such as parking assist cameras that remain partially active during vehicle sleep states.
Is TLV70225QDSERQ1 pin-compatible with other TLV702-Q1 variants?
No - TLV70225QDSERQ1 uses the 6-pin WSON (DSE) package with pin 1=IN, pin 2=GND, pin 3=OUT, pin 4=NC, pin 5=NC, pin 6=EN. This differs from the 5-pin SOT-23 (DBV/DDC) variants, which have no NC pins and assign EN to pin 3. PCB layout and footprint must be redesigned when migrating between WSON and SOT packages, despite identical electrical functionality.
