Product details
Overview
TLV70230QDSERQ1 from Texas Instruments is an automotive-grade, 300-mA, fixed-output 3.0 V 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, 220 mV dropout at 300 mA, and 68 dB PSRR at 1 kHz - enabling reliable power for image sensor rails and microprocessor I/O supplies in automotive camera modules.
For engineers reviewing the TLV70230QDSERQ1 datasheet, TLV70230QDSERQ1 pinout, TLV70230QDSERQ1 application, or TLV70230QDSERQ1 equivalent, key selection criteria 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 TLV70230QDSERQ1 uses a PMOS pass transistor architecture to achieve low dropout and high PSRR. Its precision bandgap reference and error amplifier maintain 2% DC accuracy across temperature and load, while internal UVLO prevents startup below 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

Pinout & Package
TLV70230QDSERQ1 is packaged 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 modules.
| 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 suppression and stability. |
| GND (Pin 2) | Power ground reference | Single-point connection for IN and OUT return paths; critical for PSRR and noise performance - must tie directly to output capacitor ground. |
| 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 sequencing. |
| OUT (Pin 3) | Regulated 3.0 V output | Delivers up to 300 mA; requires ≥0.1 µF effective ceramic capacitance to GND; sensitive to layout-induced ESR/inductance. |
| NC (Pins 4 & 5) | No-connect thermal pads | Internally tied to die paddle; must be soldered to PCB thermal pad for optimal RθJB (281.5°C/W) and reliability in automotive duty cycles. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV70230QDBVRQ1 | Same electrical specs, but in 5-pin SOT-23 (DBV) package (2.9 mm × 1.6 mm); higher RθJA (249.2°C/W) vs WSON's 321.3°C/W. | Suitable for less thermally demanding layouts where board area is less constrained than height; lacks wettable flanks for AOI. | Select TLV70230QDBVRQ1 only if SOT-23 footprint compatibility or legacy design reuse is required; WSON preferred for new automotive modules. |
| TPS7A0530PDBVR | Non-automotive grade (no AEC-Q100); 200 mA max output; 25 µA IQ; 170 mV dropout at 200 mA; same 3.0 V fixed output. | Limited to industrial or consumer applications; not qualified for under-hood or camera module use per ISO 26262 functional safety requirements. | Use TPS7A0530PDBVR only in non-safety-critical designs; TLV70230QDSERQ1 remains mandatory for AEC-Q100-compliant automotive systems. |

FAQ
What is the maximum input voltage rating for TLV70230QDSERQ1?
The absolute maximum input voltage for TLV70230QDSERQ1 is 6.0 V, as specified in the Absolute Maximum Ratings table. Operation above this voltage risks permanent damage. For reliable functionality, the recommended input range is 2.0 V to 5.5 V - ensuring proper regulation across automotive battery variations including cold-crank (down to ~6.5 V transient) when used with appropriate input filtering.
Does TLV70230QDSERQ1 require an input capacitor?
While TLV70230QDSERQ1 is stable without an input capacitor, TI 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 mitigates voltage excursions caused by source impedance - especially critical in automotive environments with noisy battery lines and long harness runs feeding the regulator.
How does the enable pin (EN) function on TLV70230QDSERQ1?
The EN pin on TLV70230QDSERQ1 is active-high: the regulator turns on when EN ≥ 0.9 V and enters ultra-low-power shutdown (1 µA typical ground current) when EN ≤ 0.4 V. It is compatible with 1.8 V and 3.3 V logic levels. If enable functionality is unused, TI recommends tying EN directly to IN to ensure always-on operation - avoiding floating inputs that could cause erratic behavior.
Can TLV70230QDSERQ1 operate with a 0.1 µF output capacitor?
Yes - TLV70230QDSERQ1 is explicitly designed to be stable with an effective output capacitance of ≥0.1 µF, provided the capacitor's bias- and temperature-derated value meets this threshold. This enables use of compact 0402/0603 X5R/X7R ceramics, reducing PCB area and BOM cost in space-constrained automotive camera modules where TLV70230QDSERQ1 is commonly deployed.
What thermal protection behavior does TLV70230QDSERQ1 exhibit under overload?
TLV70230QDSERQ1 activates thermal shutdown at approximately 165°C junction temperature and resets at ~145°C. Under sustained overload, it cycles between regulation and shutdown - limiting average power dissipation and preventing catastrophic failure. For reliable operation, design must keep steady-state TJ ≤ 125°C using the WSON package's NC pins soldered to a thermal pad and adequate copper area per TI's layout guidelines.
