Texas Instruments TLV70726DQNT

Overview

TLV70726DQNT from Texas Instruments is a 200-mA, low-quiescent-current (25 µA), low-noise LDO regulator with 2.6 V fixed output voltage, 0.5% DC accuracy, and 70 dB PSRR at 100 Hz - designed for power-sensitive portable electronics such as wearables and smartphone subsystems.

For engineers reviewing the TLV70726DQNT datasheet, TLV70726DQNT pinout, TLV70726DQNT application, or TLV70726DQNT equivalent, key selection criteria include dropout voltage (325 mV @ 150 mA), thermal shutdown/overcurrent protection, stability with ≥0.1 µF output capacitance, and compatibility with low-voltage GPIO enable logic (VIH = 0.9 V).

Technical Context

The TLV70726DQNT implements a PMOS pass transistor architecture enabling ultra-low dropout and fast load transient response. Its internal bandgap reference and error amplifier deliver 0.5% output accuracy across –40°C to +125°C junction temperature and 0–200 mA load range.

It features active-high enable with 0.9 V VIH threshold, 1 µA shutdown current, and integrated thermal shutdown plus current limiting. The TLV70726DQNT variant belongs to the TLV707 series (not TLV707P), so it lacks the 120-Ω active pulldown circuit - confirmed by absence of RPULLDOWN specification in its electrical characteristics table.

Key Specifications

Pinout & Package

TLV70726DQNT uses the DQN (X2SON) 4-pin package: 1.00 mm × 1.00 mm body with exposed thermal pad. This ultra-compact, leadless package supports high-density layouts in space-constrained portable designs.

FAQ

What is the maximum input voltage rating for TLV70726DQNT?

The absolute maximum input voltage for TLV70726DQNT is 6.0 V. Operation beyond this risks permanent damage. For reliable continuous use, TI specifies 2.0 V to 5.5 V as the recommended input range - sufficient to cover single-cell Li-ion (2.7–4.2 V), USB (5.0 V), and boosted rails. Always observe derating guidelines per the Absolute Maximum Ratings table in the SBVS153G datasheet.

Does TLV70726DQNT include an active pulldown circuit on the output?

No, TLV70726DQNT does not include an active pulldown circuit. It belongs to the standard TLV707 family (not TLV707P), and the datasheet confirms RPULLDOWN = N/A for this variant. Only TLV707P parts feature the 120-Ω internal discharge path. For rapid output discharge in TLV70726DQNT designs, an external pulldown resistor or MOSFET switch is required.

Can TLV70726DQNT operate with no load connected to the output?

Yes, TLV70726DQNT maintains its specified 0.5% output voltage accuracy even with zero load current. This is explicitly confirmed in the datasheet description and electrical characteristics table. No minimum load is required - simplifying designs for intermittent-use subsystems like wake-on-motion sensors or low-duty-cycle telemetry.

What is the thermal resistance (RθJA) of TLV70726DQNT in its DQN package?

The junction-to-ambient thermal resistance (RθJA) for TLV70726DQNT in the DQN (X2SON) 4-pin package is 208.1°C/W, as measured per JEDEC JESD51 standards on a 2-layer board with 1-in² copper. This value assumes standard layout practices - including proper thermal pad soldering and adequate copper pour. Higher ambient temperatures require derating output current per the Thermal Information table.

Is TLV70726DQNT RoHS-compliant and REACH-conformant?

Yes, TLV70726DQNT is RoHS-compliant (lead-free, halogen-free) and meets REACH SVHC requirements. Texas Instruments certifies this part under its corporate environmental compliance program, with full material declarations available via TI's Quality & Environmental Data portal. The DQN package uses matte tin terminal finish and green molding compound.
