Texas Instruments TLV71210DSET

Overview

TLV71210DSET from Texas Instruments is a 1.0-V fixed-output, 300-mA sub-bandgap low-dropout (LDO) regulator in a 1.5-mm × 1.5-mm SON-6 package. It delivers 2% DC output accuracy, 35 µA quiescent current, and operates from 2.0 V to 5.5 V input with stable regulation down to 0.7 V output-enabling direct power for ultra-low-voltage processors in space-constrained portable devices.

For engineers reviewing the TLV71210DSET datasheet, TLV71210DSET pinout, TLV71210DSET application, or TLV71210DSET equivalent, this page provides verified electrical specifications, thermal performance data, EN-controlled shutdown behavior, output stability with 0.1 µF ceramic capacitors, and validated alternative options for battery-powered RF and embedded systems requiring sub-1.2-V supply rails.

Technical Context

The TLV71210DSET uses a PMOS pass transistor to achieve low dropout across its 0.7–1.15 V output range, with undervoltage lockout (UVLO) activating at 1.9 V to prevent erratic startup. Its internal bandgap reference and error amplifier deliver ±20 mV DC accuracy over –40°C to +125°C junction temperature.

It integrates thermal shutdown (trip at +165°C, reset at +145°C) and current limiting (320–860 mA), supports active-high enable with 0.9 V logic threshold, and maintains 68 dB PSRR at 1 kHz-critical for noise-sensitive RF baseband and sensor signal chains powered from shared Li-ion rails.

Key Specifications

Pinout & Package

TLV71210DSET is housed in a thermally enhanced 1.5-mm × 1.5-mm, 0.75-mm height WSON-6 (DSE) package with exposed thermal pad. The package supports high-density PCB layouts and offers 180°C/W junction-to-ambient thermal resistance on a standard 2-layer board.

FAQ

What is the maximum output current supported by the TLV71210DSET?

The TLV71210DSET supports up to 300 mA continuous output current. Its internal current limit is specified from 320 mA to 860 mA depending on input voltage and temperature, ensuring safe operation during short-term transients without external current-sense circuitry. This rating holds across the full –40°C to +125°C junction temperature range with proper PCB thermal design.

Does the TLV71210DSET require an input capacitor for stability?

The TLV71210DSET does not require an input capacitor for basic stability, but Texas Instruments recommends a 0.1–1.0 µF low-ESR ceramic capacitor between IN and GND. This improves line transient response, suppresses input ripple from upstream switching regulators, and mitigates source impedance effects-especially critical when the device is located >2 cm from the power source or when source impedance exceeds 2 Ω.

Can the TLV71210DSET operate with a 1.8-V input supply?

No-the TLV71210DSET has a minimum input voltage of 2.0 V per its absolute maximum ratings and electrical characteristics table. At 1.8 V input, the device enters undervoltage lockout (UVLO) and disables regulation. It is designed for use with single-cell Li-ion (3.0–4.2 V), NiMH, or regulated 2.5/3.3/5.0 V rails-not 1.8-V sources.

What is the thermal performance of the TLV71210DSET in its DSE package?

On a standard 2-layer PCB with 2 oz copper, the TLV71210DSET (DSE package) has a junction-to-ambient thermal resistance (R_θJA) of 180°C/W. This enables 555 mW power dissipation at +25°C ambient, derating to 222 mW at +85°C ambient. For reliable operation, the junction temperature must remain ≤+125°C-requiring appropriate copper area, thermal vias, and layout per TI's recommended land pattern in Figure 24.

Is the TLV71210DSET pin-compatible with other members of the TLV712xx family?

Yes-within the same package type. All TLV712xx devices in the SON-6 (DSE) package-including TLV71209DSET, TLV71210DSET, and TLV71211DSET-share identical pinout, footprint, and terminal functions. Only the output voltage differs (0.9 V, 1.0 V, 1.1 V respectively), allowing drop-in replacement in designs where voltage tolerance permits.
