Product details
Overview
TLV70729DQNR from Texas Instruments is a 200-mA, low-quiescent-current (25 µA), low-noise LDO regulator with 2.9-V fixed output voltage, 0.5% DC accuracy, and 70 dB PSRR at 100 Hz - designed for power-sensitive portable electronics such as smartphones, wearables, and WLAN add-on cards.
For engineers reviewing the TLV70729DQNR datasheet, TLV70729DQNR pinout, TLV70729DQNR application, or TLV70729DQNR equivalent, key selection criteria include dropout voltage (325 mV at 150 mA), stability with 0.1-µF output capacitance, thermal/overcurrent protection, and enable-pin logic thresholds (VIH = 0.9 V, VIL = 0.4 V).
Technical Context
The TLV70729DQNR uses 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 no load regulation capability.
It integrates active-high enable logic with shutdown current of 1 µA and supports stable operation with ceramic capacitors as small as 0.1 µF - eliminating need for ESR-tuned tantalum or aluminum electrolytics in space-constrained designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.9 V ±0.5% - ensures precise rail generation for 2.8–3.0 V logic domains without external feedback. |
| Max Output Current | 200 mA - supports moderate-power RF ICs, sensors, and microcontrollers in portable systems. |
| Quiescent Current | 25 µA - enables multi-week battery life in always-on wearable and IoT sensor nodes. |
| PSRR | 70 dB at 100 Hz, 50 dB at 1 MHz - suppresses switching noise from adjacent DC/DC converters feeding shared input rails. |
| Dropout Voltage | 325 mV at 150 mA - allows operation from 3.225 V input, compatible with single-cell Li-ion (3.0–3.6 V) under load. |
| Stability Capacitance | 0.1 µF min effective COUT - permits use of 0402/0201 X5R/X7R ceramics, reducing PCB area by >50% vs legacy 1-µF solutions. |
| Enable Threshold | VIH = 0.9 V, VIL = 0.4 V - interoperable with low-voltage GPIOs (e.g., 1.8-V I/O banks) without level-shifting. |
Pinout & Package
TLV70729DQNR is housed in a 1.0 mm × 1.0 mm DQN (X2SON-4) package with wettable flank terminals for automated optical inspection (AOI). Thermal pad on bottom enhances heat dissipation in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Regulated output | Delivers stable 2.9 V; requires ≥0.1 µF ceramic capacitor to GND for stability and transient response. |
| GND (Pin 2) | Power ground | Reference node for regulation and enable logic; must be low-impedance connection to system ground plane. |
| EN (Pin 3) | Enable control input | Active-high logic: device enabled when ≥0.9 V applied; shutdown draws only 1 µA when ≤0.4 V. |
| IN (Pin 4) | Input supply | Accepts 2.0–5.5 V input; requires local 1-µF ceramic bypass capacitor to minimize high-frequency noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise operation | 45 µVRMS (100 Hz–100 kHz) - preserves signal integrity in analog front-ends and RF receivers. |
| Thermal shutdown | Activates at ~150°C junction temperature - prevents permanent damage during sustained overload or poor heatsinking. |
| Overcurrent protection | 240–450 mA current limit - safeguards against short-circuit faults while maintaining predictable foldback behavior. |
| Wide input range | 2.0–5.5 V operation - accommodates single-cell Li-ion, USB-powered, and multi-rail intermediate bus architectures. |
| No-load regulation | Maintains 0.5% accuracy with zero output current - critical for standby-mode power sequencing in battery-backed systems. |

FAQ
What is the maximum input voltage rating for TLV70729DQNR?
The absolute maximum input voltage for TLV70729DQNR is 6.0 V. However, the recommended operating range is 2.0 V to 5.5 V. Exceeding 6.0 V risks permanent damage, and operation above 5.5 V voids guaranteed specifications including dropout, accuracy, and PSRR performance.
Does TLV70729DQNR require an external pull-up resistor on the EN pin?
No, TLV70729DQNR does not require an external pull-up resistor on the EN pin. The device operates correctly with EN directly tied to IN for always-on operation, or driven by a low-voltage GPIO (≥0.9 V logic high). Internal circuitry ensures reliable enable/disable without external biasing components.
Can TLV70729DQNR be used with a 0.1-µF output capacitor in production designs?
Yes, TLV70729DQNR is explicitly characterized and guaranteed stable with a minimum effective output capacitance of 0.1 µF - verified across temperature, input voltage, and load conditions. This applies to X5R/X7R ceramics derated for bias and temperature, enabling smaller, lower-cost capacitor selections.
What is the thermal resistance (RθJA) of TLV70729DQNR in its DQN package?
The junction-to-ambient thermal resistance (RθJA) of TLV70729DQNR in the 1-mm × 1-mm DQN (X2SON-4) package is 208.1°C/W under standard JEDEC test conditions (JESD51-2). Actual thermal performance improves significantly with PCB copper pour connected to the thermal pad.
Is TLV70729DQNR pin-compatible with other TLV707x variants?
Yes, TLV70729DQNR is pin-compatible with all TLV707x DQN-4 variants (e.g., TLV70712DQNR, TLV70733DQNR), sharing identical pinout (IN, GND, EN, OUT), package dimensions, and thermal pad layout - enabling voltage-scaling flexibility without PCB redesign.
