Texas Instruments TLV70213QDSERQ1

Overview

TLV70213QDSERQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified 300-mA low-dropout linear regulator with fixed 1.3-V output, 2% accuracy over –40°C to +125°C, 35 µA quiescent current, and 220 mV dropout at 300 mA. It delivers stable power to image sensor rails and microprocessor cores in space-constrained automotive camera modules.

For engineers reviewing the TLV70213QDSERQ1 datasheet, TLV70213QDSERQ1 pinout, TLV70213QDSERQ1 application, or TLV70213QDSERQ1 equivalent, key selection criteria include dropout performance at full load, PSRR above 1 kHz, thermal shutdown behavior, and compatibility with 0.1 µF ceramic output capacitors in high-temperature environments.

Technical Context

The TLV70213QDSERQ1 uses a PMOS pass transistor architecture enabling ultra-low dropout voltage scaling with load current. Its precision bandgap reference and error amplifier maintain ±2% output regulation across temperature and line/load variations.

Functional modes include normal regulation (VIN > VOUT + VDO), dropout operation (VIN < VOUT + VDO), and current-limit protection triggered at ≥320 mA. Integrated undervoltage lockout activates below 1.9 V input, and thermal shutdown engages at 165°C junction temperature with hysteresis reset at 145°C.

Key Specifications

Pinout & Package

TLV70213QDSERQ1 is packaged in a 6-pin WSON (DSE) package measuring 1.5 mm × 1.5 mm with 0.5-mm pitch and wettable flank terminations for automated optical inspection. The exposed thermal pad is electrically connected to GND and must be soldered to a thermal land on the PCB.

FAQ

What is the maximum input voltage rating for TLV70213QDSERQ1?

The absolute maximum input voltage for TLV70213QDSERQ1 is 6.0 V, as specified in the Absolute Maximum Ratings table. Operation above this voltage risks permanent damage. For reliable long-term use, TI recommends staying within the recommended operating range of 2.0 V to 5.5 V, especially under high-temperature conditions where thermal stress increases.

Does TLV70213QDSERQ1 require an input capacitor?

While TLV70213QDSERQ1 does not require an input capacitor for stability, TI strongly recommends using a 0.1–1 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 - particularly important in automotive wiring harnesses with inductive characteristics.

Can TLV70213QDSERQ1 operate with a 0.1 µF output capacitor?

Yes, TLV70213QDSERQ1 is explicitly designed to be stable with an effective output capacitance of 0.1 µF or greater. This includes X5R/X7R ceramic capacitors in 0201 or 0402 packages, provided their bias- and temperature-derated capacitance remains ≥0.1 µF at the operating voltage and temperature - enabling significant BOM and footprint reduction.

What is the shutdown current of TLV70213QDSERQ1 when EN is low?

When the EN pin is held ≤0.4 V, TLV70213QDSERQ1 enters shutdown mode with a typical ground current of 1 µA at 2 V input, rising to 2.5 µA maximum across 2–4.5 V input range. This ultra-low shutdown current supports energy harvesting and battery-backed systems where leakage must remain below 5 µA.

Is TLV70213QDSERQ1 pin-compatible with other TLV702-Q1 variants?

Yes, all TLV702-Q1 devices in the 6-pin WSON (DSE) package - including TLV70213QDSERQ1 - share identical pinout, footprint, and thermal pad layout. Fixed-output versions from 1.2 V to 4.8 V are mechanically and electrically interchangeable, differing only in output voltage setting and minor electrical tolerances.
