Texas Instruments TLV70736DQNR

Overview

TLV70736DQNR from Texas Instruments is a 200-mA, low-quiescent-current (25 µA), low-noise LDO regulator with 3.6-V fixed output voltage, 0.5% DC accuracy, and 70 dB PSRR at 100 Hz - designed for power-sensitive portable electronics requiring stable low-voltage rail generation.

For engineers reviewing the TLV70736DQNR datasheet, TLV70736DQNR pinout, TLV70736DQNR application, or TLV70736DQNR equivalent, key selection criteria include dropout voltage (220 mV at 150 mA), thermal shutdown/overcurrent protection, stability with 0.1-µF output capacitance, and compatibility with low-voltage GPIO enable signals (VIH = 0.9 V).

Technical Context

The TLV70736DQNR employs a PMOS pass transistor architecture enabling ultra-low dropout and high PSRR across 100 Hz–1 MHz. Its internal bandgap reference and error amplifier deliver 0.5% output accuracy over –40°C to +125°C junction temperature, with load regulation of ≤20 mV from 0–150 mA.

It features active-high enable logic (VIH = 0.9 V, VIL = 0.4 V), 1-µA shutdown current, and integrated thermal shutdown + current limiting. The device operates with input voltages from 2.0 V to 5.5 V and regulates accurately even at zero load.

FAQ

What is the minimum input voltage required for TLV70736DQNR to maintain regulation at full load?

The TLV70736DQNR requires VIN ≥ VOUT + V(DO). At 150 mA output, its dropout voltage is 220 mV, so minimum input is 3.6 V + 0.22 V = 3.82 V. With 200 mA load, dropout rises to 270 mV, requiring ≥3.87 V. For reliable operation across temperature, design for ≥4.0 V input minimum.

Does TLV70736DQNR require an external pull-up resistor on the EN pin?

No - TLV70736DQNR has no internal pull-up on EN. To ensure reliable startup, connect EN to IN via a 100-kΩ resistor or drive it actively from a GPIO. Leaving EN floating may cause erratic enable behavior due to noise coupling.

Can TLV70736DQNR be used with a 0.1-µF X5R ceramic capacitor for stability?

Yes - TLV70736DQNR is explicitly characterized for stability with ≥0.1-µF effective output capacitance. A 0.1-µF, 6.3-V X5R 0201 capacitor provides sufficient effective capacitance after bias and temperature derating, enabling ultra-compact layout.

How does TLV70736DQNR behave during thermal shutdown?

When junction temperature exceeds ~150°C, TLV70736DQNR disables the pass transistor and enters thermal shutdown. It remains off until temperature drops ~20°C below trip point, then automatically recovers. During sustained overload, it cycles between regulation and shutdown - visible as output voltage pulsing.

Is TLV70736DQNR pin-compatible with other devices in the TLV707 family?

Yes - all TLV707x and TLV707Px variants (including TLV70736DQNR) share identical DQN-4 pinout and package dimensions. Voltage variants differ only in internal feedback network; no PCB changes are needed when substituting within the same package option.
