Product details
Overview
TLV70730ADQNR from Texas Instruments is a 200-mA, low-quiescent-current (25 µA), low-noise LDO regulator with 3.0 V fixed output voltage in a 1-mm × 1-mm X2SON (DQN) package. It delivers ±0.5% DC accuracy, 70 dB PSRR at 100 Hz, and stable operation with only 0.1 µF output capacitance-enabling compact, cost-effective power delivery for battery-powered RF subsystems in portable electronics.
For engineers reviewing the TLV70730ADQNR datasheet, TLV70730ADQNR pinout, TLV70730ADQNR application, or TLV70730ADQNR equivalent, key selection criteria include dropout voltage (≤250 mV at 150 mA for 3.0 V output), shutdown current (1 µA), EN pin logic thresholds (VIH = 0.9 V, VIL = 0.4 V), thermal protection, and compatibility with space-constrained layouts requiring minimal external components.
Technical Context
The TLV70730ADQNR uses a PMOS pass transistor architecture enabling ultra-low dropout and fast transient response without requiring external compensation. Its internal bandgap reference and error amplifier maintain tight regulation across –40°C to +125°C junction temperature while supporting load currents up to 200 mA.
It integrates active-high enable logic with hysteresis-free thresholding, thermal shutdown, and foldback current limiting. Unlike the TLV707P variant, TLV70730ADQNR lacks an internal pulldown resistor-confirming it is the standard TLV707 (not TLV707P) family member per device nomenclature and functional block diagram.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 3.0 V ±0.5% - ensures precise biasing for 3.0-V logic, RF ICs, and sensors without external feedback. |
| Max output current | 200 mA - supports moderate-power peripherals like Bluetooth radios, display drivers, or MCU cores in handheld devices. |
| Quiescent current | 25 µA - extends battery life in always-on or low-duty-cycle applications such as wearables and remote controls. |
| PSRR | 70 dB at 100 Hz - suppresses low-frequency supply noise from switching converters feeding the LDO input. |
| Stable with COUT | 0.1 µF ceramic - allows use of small, low-cost capacitors with high bias/temperature derating, reducing PCB area and BOM cost. |
| Dropout voltage | 250 mV at 150 mA (3.0 V output) - enables operation down to VIN = 3.25 V, critical for single-cell Li-ion or Li-poly systems under load. |
| Shutdown current | 1 µA - minimizes leakage during system sleep modes without requiring external discharge circuitry. |
Pinout & Package
TLV70730ADQNR is housed in a 4-pin, 1.0 mm × 1.0 mm X2SON (DQN) package with wettable flank terminations for automated optical inspection. The thermal pad on the bottom enhances power dissipation in high-ambient environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Regulated output | Delivers stable 3.0 V to load; requires ≥0.1 µF ceramic capacitor to GND for stability and transient response. |
| GND (Pin 2) | Ground reference | Common return path for IN, OUT, and EN; must be low-impedance and thermally coupled to PCB copper pour. |
| EN (Pin 3) | Enable control | Active-high logic input; asserts regulator when ≥0.9 V, disables it when ≤0.4 V-compatible with modern low-voltage GPIOs. |
| IN (Pin 4) | Input supply | Accepts 2.0–5.5 V input; requires local 1-µF ceramic decoupling to GND near the pin for optimal transient immunity. |
Key Features
| Feature | Design Value |
|---|---|
| ±0.5% output accuracy | Ensures reliable operation of voltage-sensitive analog and RF circuits without calibration overhead. |
| 70 dB PSRR @ 100 Hz | Rejects ripple from upstream DC/DC converters, preserving signal integrity in audio and wireless receivers. |
| 0.1 µF minimum COUT | Reduces solution size and cost by enabling use of smaller, higher-bias-rated ceramics instead of larger tantalum or polymer caps. |
| Thermal shutdown + current limit | Protects against sustained overloads or short circuits without external supervision circuitry-critical for unattended portable devices. |
| 25 µA quiescent current | Extends shelf life and runtime in battery-backed real-time clocks, IoT sensors, and energy-harvesting nodes. |
Applications
| Smartphone Subsystem Power | Wearable Sensor Hub |
|---|---|
Use Scenario: Powering 3.0-V RF transceivers (e.g., Bluetooth LE modules) and baseband processors during active transmission bursts. IC Role / Device Role / Timing Role: Primary low-noise post-regulator delivering clean, stable 3.0 V from a shared 3.6-V switched-mode supply rail. Use Value: 70 dB PSRR at 100 Hz suppresses switching noise from the upstream buck converter, preventing receiver desensitization. | Use Scenario: Supplying 3.0-V MEMS accelerometers, gyroscopes, and ultra-low-power MCUs in fitness trackers with multi-day battery life. IC Role / Device Role / Timing Role: Always-on LDO maintaining regulated voltage during deep-sleep cycles where system current drops below 10 µA. Use Value: 25 µA IQ and 1 µA shutdown current minimize quiescent drain, directly extending operational time between charges. |
| PC Add-in Card Biasing | Set-Top Box USB Peripheral Port |
Use Scenario: Providing isolated 3.0-V bias to WLAN or Wi-Fi 6E M.2 modules mounted on PCIe add-in cards with limited board space. IC Role / Device Role / Timing Role: Compact point-of-load regulator placed adjacent to the RF IC to minimize trace inductance and EMI coupling. Use Value: 1.0 mm × 1.0 mm DQN package fits within tight keep-out zones near edge connectors while supporting 200 mA peak loads. | Use Scenario: Powering externally connected USB peripherals (e.g., HDMI CEC adapters, IR blasters) from a 5-V main rail in set-top boxes. IC Role / Device Role / Timing Role: Standby-capable LDO that remains enabled during system standby but shuts down when host controller deactivates the port. Use Value: Active-high EN pin with 0.9-V VIH allows direct interfacing with 3.3-V GPIOs without level-shifting, simplifying control logic. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC70730DBVR | Higher IQ (55 µA), same 3.0 V output and DFN package; no EN pin-always-on operation. | Lacks enable control; unsuitable for power-gated subsystems requiring dynamic on/off sequencing. | Select when simplicity and lowest possible footprint are prioritized over power-state flexibility. |
| TPS7A0530PDQNR | Lower IQ (25 nA typical), same 3.0 V output and 1-mm X2SON package; includes EN pin with identical thresholds. | Optimized for ultra-low-power applications (e.g., coin-cell devices); lower max output current (200 mA vs. 300 mA). | Select when nanoscale quiescent current is mandatory and peak load stays ≤200 mA. |
Compared with TLC70730DBVR and TPS7A0530PDQNR, TLV70730ADQNR provides the best balance of low IQ (25 µA), integrated enable functionality, and robust 200-mA capability-making it ideal for portable systems requiring both efficiency and controllability without sacrificing performance headroom.

FAQ
What is the maximum input voltage rating for TLV70730ADQNR?
The absolute maximum input voltage for TLV70730ADQNR 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 TLV70730ADQNR include an internal pulldown resistor on the OUT pin?
No, TLV70730ADQNR does not include an internal pulldown resistor. That feature is exclusive to the TLV707P variant (e.g., TLV70730P). TLV70730ADQNR is the standard TLV707 version, confirmed by its absence in the TLV707P-specific features table and functional block diagram.
What output capacitor value is required for stable operation of TLV70730ADQNR?
TLV70730ADQNR is stable with an effective output capacitance of ≥0.1 µF. A 0.47 µF or 1.0 µF X5R/X7R ceramic capacitor is recommended for optimal transient response and margin, but the minimum effective capacitance-including bias and temperature derating-must remain ≥0.1 µF at operating conditions.
Can TLV70730ADQNR operate with zero load current?
Yes, TLV70730ADQNR regulates to specified accuracy (±0.5%) with no output load. Its design maintains stability and voltage accuracy from 0 mA to 200 mA, making it suitable for standby and wake-up scenarios where downstream circuitry may be fully powered down.
What is the thermal resistance (RθJA) of TLV70730ADQNR in its DQN package?
The junction-to-ambient thermal resistance (RθJA) for TLV70730ADQNR in the 4-pin X2SON (DQN) package is 208.1°C/W, measured under standard JEDEC JESD51-2 conditions. This value assumes a 1-in² 2-oz copper pad with two thermal vias; actual board layout significantly impacts real-world thermal performance.
