Texas Instruments TLV707115DQNT

Overview

TLV707115DQNT from Texas Instruments is a 200-mA, low-quiescent-current (25 μA), low-noise LDO regulator with 1.15-V fixed output voltage, 0.5% DC accuracy, and stable operation with only 0.1-μF output capacitance. It features thermal shutdown, overcurrent protection, and high PSRR (70 dB at 100 Hz), designed for power-sensitive portable electronics such as wearable sensors and wireless handsets.

For engineers reviewing the TLV707115DQNT datasheet, TLV707115DQNT pinout, TLV707115DQNT application, or TLV707115DQNT equivalent, key selection criteria include dropout voltage at 150 mA (220–270 mV for 1.15-V output), enable-pin logic thresholds (VIH = 0.9 V, VIL = 0.4 V), shutdown current (1 μA), and compatibility with space-constrained 1-mm × 1-mm X2SON packaging.

Technical Context

The TLV707115DQNT employs a PMOS pass transistor architecture enabling ultra-low dropout and minimal ground current variation across load and input voltage. Its internal bandgap reference and error amplifier deliver tight regulation (±1.5% over temperature and line/load) without requiring an output load to maintain accuracy.

Unlike standard LDOs, it achieves stability with 0.1-μF effective output capacitance-enabling use of small-footprint, bias-voltage-derated ceramics-and integrates active-high enable control with sub-1-μA shutdown current, supporting dynamic power sequencing in battery-powered systems.

FAQ

What is the minimum input voltage required for TLV707115DQNT to regulate 1.15 V at 150 mA?

The TLV707115DQNT requires a minimum input voltage of 1.37 V (1.15 V + 220 mV dropout) to maintain regulation at 150 mA. Per datasheet Section 6.5, dropout is 220–270 mV under those conditions, so VIN must exceed VOUT + dropout to avoid foldback. Operation below this threshold results in unregulated output.

Does TLV707115DQNT include an active pulldown circuit on the output pin?

No, TLV707115DQNT does not include an active pulldown circuit. That feature is exclusive to the TLV707P variant (e.g., TLV707115PDQNT). The TLV707115DQNT relies on external discharge paths or natural load decay during shutdown, with only 1 μA typical shutdown current.

Can TLV707115DQNT operate without any load connected to the OUT pin?

Yes, TLV707115DQNT regulates to specified accuracy (±1.5%) even with zero output load. This is explicitly confirmed in the datasheet Description section: "These devices also regulate to the specified accuracy with no output load," making it suitable for standby-biased circuits.

What is the maximum allowable input voltage for TLV707115DQNT?

The absolute maximum input voltage for TLV707115DQNT is 6.0 V, per Absolute Maximum Ratings (Section 6.1). However, the recommended operating range is 2.0 V to 5.5 V. Exceeding 5.5 V may cause permanent damage or accelerated aging, even if within absolute limits.

Is TLV707115DQNT compatible with 0.1-μF X5R ceramic capacitors rated at 6.3 V?

Yes, TLV707115DQNT is stable with 0.1-μF X5R ceramics rated at 6.3 V, provided their effective capacitance remains ≥0.1 μF under actual bias and temperature conditions. The datasheet confirms stability with "effective capacitance of 0.1 μF" - meaning post-derating value - not nominal rating.
