Texas Instruments TLV70215QDSERQ1

Overview

TLV70215QDSERQ1 from Texas Instruments is an automotive-grade, 300-mA, fixed 1.5-V output 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 use in power-sensitive automotive camera modules and image sensor rails.

For engineers reviewing the TLV70215QDSERQ1 datasheet, TLV70215QDSERQ1 pinout, TLV70215QDSERQ1 application, or TLV70215QDSERQ1 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 TLV70215QDSERQ1 employs a PMOS pass transistor architecture to achieve ultra-low dropout voltage that scales with load current - 260 mV at 300 mA and 37 mV at 50 mA for VOUT = 2.8 V (typical). Its precision bandgap reference and error amplifier ensure ±2% DC accuracy across temperature and line/load conditions.

Functional modes include normal regulation, dropout operation (where VOUT = VIN − VDO), and current-limit protection triggered above 320 mA. Integrated undervoltage lockout (UVLO) activates below 1.9 V input, while thermal shutdown engages at 165°C junction temperature and resets at 145°C.

FAQ

What is the maximum input voltage rating for TLV70215QDSERQ1?

The absolute maximum input voltage for TLV70215QDSERQ1 is 6.0 V, as specified in the Absolute Maximum Ratings table. Operation above this level risks permanent device damage. For reliable continuous operation, TI specifies a recommended maximum input of 5.5 V across the full temperature range - ensuring safe margin against transients and maintaining 2% output accuracy.

Does TLV70215QDSERQ1 require an input capacitor?

While TLV70215QDSERQ1 is stable without an input capacitor, TI strongly recommends a 0.1–1 µF low-ESR ceramic capacitor between IN and GND. This improves transient response, reduces input ripple coupling, and prevents instability when source impedance exceeds 2 Ω - especially critical in automotive wiring harness environments with inductive parasitics.

Can TLV70215QDSERQ1 be used with output capacitance less than 1 µF?

Yes - TLV70215QDSERQ1 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 X5R/X7R ceramics rated at 0.1 µF/6.3 V, reducing board area and cost versus traditional 1–2.2 µF solutions - provided ESR remains below 200 mΩ.

What is the thermal shutdown behavior of TLV70215QDSERQ1?

TLV70215QDSERQ1 activates thermal shutdown at approximately 165°C junction temperature and resets at ~145°C. During sustained overload, it cycles between regulation and shutdown - a protective mechanism that prevents permanent damage. Continuous cycling indicates inadequate PCB copper area or excessive power dissipation; TI recommends limiting steady-state T_J to ≤125°C for reliability.

Is TLV70215QDSERQ1 pin-compatible with other TLV702-Q1 variants?

TLV70215QDSERQ1 shares the same 6-pin WSON (DSE) package and pinout with all TLV702-Q1 devices in that package - including TLV70218QDSERQ1 and TLV70233QDSERQ1. Pin functions (IN, GND, EN, OUT, NC, NC) are identical; only the internal feedback network differs to set the fixed output voltage - enabling drop-in replacement across output voltages within the same package.
