Texas Instruments TLV70227QDSERQ1

Overview

TLV70227QDSERQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified 300-mA low-dropout linear regulator with fixed 2.7 V output, 35 µA quiescent current, 2% output accuracy over –40°C to +125°C, and 68 dB PSRR at 1 kHz - designed for image sensor power rails and microprocessor core supplies in camera modules and infotainment head units.

For engineers reviewing the TLV70227QDSERQ1 datasheet, TLV70227QDSERQ1 pinout, TLV70227QDSERQ1 application, or TLV70227QDSERQ1 equivalent, key selection criteria include dropout voltage at 300 mA (260–375 mV), thermal shutdown threshold (165°C), enable pin logic (active-high, 0.9 V turn-on), stability with ≥0.1 µF ceramic output capacitance, and WSON-6 package thermal resistance (R_θJA = 321.3°C/W).

Technical Context

The TLV70227QDSERQ1 uses a PMOS pass transistor architecture enabling ultra-low dropout voltage scaling with load current - 260 mV typical at 300 mA - while maintaining regulation down to 1.2 V input for 2.7 V output. Its precision bandgap reference and error amplifier deliver ±2% DC accuracy across temperature and line/load conditions.

Integrated protections include thermal shutdown (trip at 165°C, reset at 145°C), current limiting (320–860 mA), undervoltage lockout (1.9 V), and active-high enable with <0.04 µA leakage. It achieves 48 µV_RMS output noise (100 Hz–100 kHz) and stable operation with 0.1 µF effective output capacitance under bias and temperature derating.

FAQ

What is the maximum input voltage rating for TLV70227QDSERQ1?

The absolute maximum input voltage for TLV70227QDSERQ1 is 6.0 V, as specified in the Absolute Maximum Ratings table. Operation above this voltage risks permanent damage. The recommended operating range is 2.0 V to 5.5 V, ensuring reliable regulation and thermal performance within AEC-Q100 Grade 1 limits.

Does TLV70227QDSERQ1 require an input capacitor?

While not strictly required for stability, TLV70227QDSERQ1 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 rails.

What is the thermal shutdown behavior of TLV70227QDSERQ1?

TLV70227QDSERQ1 activates thermal shutdown at approximately 165°C junction temperature and resets at ~145°C. During sustained overload, it cycles between shutdown and regulation. Continuous cycling degrades reliability; proper PCB copper area and NC pin grounding are essential to maintain T_J ≤125°C under full 300 mA load.

Can TLV70227QDSERQ1 operate with zero load current?

Yes, TLV70227QDSERQ1 regulates to specified 2.7 V ±2% accuracy even with no output load (I_OUT = 0 mA). Ground current remains at 35 µA typical, confirming stable no-load operation - a key requirement for always-on automotive subsystems like parking camera wake-up circuits.

Is TLV70227QDSERQ1 pin-compatible with other TLV702-Q1 variants?

TLV70227QDSERQ1 shares the same 6-pin WSON (DSE) package and pinout as all TLV702-Q1 devices in that package - including TLV70212QDSERQ1 through TLV70248QDSERQ1. Pin functions (IN, GND, EN, OUT, NC, NC) and layout are identical; only output voltage differs per variant.
