Texas Instruments TLV70726DQNR

Overview

TLV70726DQNR 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 smartphones and wearables.

For engineers reviewing the TLV70726DQNR datasheet, TLV70726DQNR pinout, TLV70726DQNR application, or TLV70726DQNR equivalent, key selection criteria include dropout voltage (325 mV @ 150 mA), stability with 0.1 µF output capacitance, thermal/overcurrent protection, and compatibility with low-voltage enable logic (VIH = 0.9 V).

Technical Context

The TLV70726DQNR 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 TLV70726DQNR variant belongs to the TLV707 series and does not include the pulldown circuit found in TLV707P devices.

FAQ

What is the output voltage tolerance of TLV70726DQNR over temperature and load?

The TLV70726DQNR maintains ±0.5% DC output accuracy across –40°C to +125°C junction temperature and 0–200 mA load range. This is confirmed in the Electrical Characteristics table under "DC output accuracy" with test conditions specifying TJ = –40°C to +85°C and IOUT = 1 mA, and validated by load regulation curves (e.g., Figure 6-2 shows <20 mV deviation from 2.8 V up to 200 mA).

Does TLV70726DQNR include an active pulldown circuit on the output?

No, TLV70726DQNR does not include an active pulldown circuit. That feature is exclusive to the TLV707P variant (e.g., TLV70726P). The TLV70726DQNR datasheet specifies no pulldown resistance parameter, and its functional block diagram lacks the 120-Ω discharge path shown in Figure 7-2 for TLV707P devices.

What is the minimum output capacitance required for TLV70726DQNR stability?

TLV70726DQNR is stable with an effective output capacitance of 0.1 µF or greater - defined as the capacitance value under actual operating bias voltage and temperature. This enables use of small-case ceramics (e.g., 0402 X5R) and reduces BOM cost and board area versus traditional 1 µF requirements.

Can TLV70726DQNR operate from a single Li-ion cell?

Yes. With a 2.6 V output and 325 mV dropout at 150 mA, TLV70726DQNR regulates down to VIN = 2.925 V - well within the 3.0–4.2 V discharge range of a standard Li-ion cell. Its 2.0 V minimum input rating further supports operation down to near-end-of-life cell voltage.

What protection features are integrated into TLV70726DQNR?

TLV70726DQNR integrates thermal shutdown and overcurrent protection. When junction temperature exceeds safe limits or output current exceeds ~240–450 mA (depending on VIN), the device enters foldback current limit and cycles between shutdown and restart until fault clears - preventing permanent damage during sustained overload or high-ambient conditions.
