Product details
Overview
TLV70710DQNT from Texas Instruments is a 200-mA, low-quiescent-current (25 μA), low-noise LDO regulator with 0.5% output accuracy and 100-mV dropout at 150 mA for 1.0-V output. It operates from 2.0 V to 5.5 V input and delivers stable regulation with only 0.1-μF output capacitance-enabling compact, cost-effective power supply design in space-constrained portable electronics.
For engineers reviewing the TLV70710DQNT datasheet, TLV70710DQNT pinout, TLV70710DQNT application, or TLV70710DQNT equivalent, key selection criteria include its ultra-low IQ for battery life extension, high PSRR (70 dB @ 100 Hz), thermal/overcurrent protection, and compatibility with small ceramic capacitors in 1-mm × 1-mm X2SON packaging.
Technical Context
The TLV70710DQNT uses a PMOS pass transistor architecture enabling low dropout and reverse-voltage tolerance via an internal body diode. Its enable circuitry accepts logic-high thresholds as low as 0.9 V, supporting direct interfacing with low-voltage GPIOs of modern processors.
It features integrated thermal shutdown and current limiting (240–450 mA typical), with shutdown current limited to 1 μA. The device maintains regulation without load and supports stable operation across –40°C to +125°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 1.0 V - eliminates external feedback network; ensures precise rail for low-voltage digital cores. |
| Max output current | 200 mA - sufficient for powering microcontrollers, sensors, and RF front-end ICs in portable devices. |
| Quiescent current | 25 μA - extends battery runtime in always-on or sleep-mode applications such as wearables and IoT endpoints. |
| Dropout voltage | 100 mV @ 150 mA - enables operation with minimal VIN–VOUT headroom (e.g., 1.1 V input for 1.0 V output). |
| PSRR | 70 dB @ 100 Hz, 50 dB @ 1 MHz - suppresses switching noise from upstream DC/DC converters in mixed-signal systems. |
| Output noise | 45 µVRMS (100 Hz–100 kHz) - suitable for noise-sensitive analog circuits like ADCs and RF synthesizers. |
| Stability capacitance | 0.1 μF minimum - allows use of small, low-cost X5R/X7R ceramics, reducing PCB area and BOM cost. |
Pinout & Package
TLV70710DQNT is housed in a 1-mm × 1-mm DQN (X2SON-4) package with wettable flank terminations for automated optical inspection. Thermal pad on bottom enhances heat dissipation in high-density layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Regulated output | Delivers stable 1.0 V; requires ≥0.1-μF ceramic capacitor to GND for stability and transient response. |
| GND (Pin 2) | Ground reference | Common return path for input/output currents; connects to thermal pad for improved thermal performance. |
| EN (Pin 3) | Enable control | Active-high logic input; device enabled when >0.9 V, disabled when <0.4 V; draws only 0.01 μA. |
| IN (Pin 4) | Input supply | Accepts 2.0–5.5 V; requires local 1-μF ceramic bypass capacitor to minimize input ripple and improve transient immunity. |
Key Features
| Feature | Design Value |
|---|---|
| 0.5% output accuracy | Ensures reliable operation of voltage-sensitive digital logic and analog peripherals without calibration. |
| 125°C max junction temperature | Supports deployment in thermally demanding environments such as enclosed handheld enclosures or near RF power stages. |
| 1 μA shutdown current | Enables true zero-power standby states in battery-powered systems with long shelf-life requirements. |
| ESD robustness | HBM ±4000 V - reduces risk of field failure during handling and assembly in standard ESD-controlled lines. |
| Load transient response | ≤50 mV deviation for 1–150 mA step load - maintains system stability during processor core wake-up bursts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC70710DBVR | Same 1.0-V fixed output, but higher IQ (45 μA) and lower PSRR (60 dB @ 100 Hz); no pulldown circuit. | Lacks active pulldown; less suitable for systems requiring rapid output discharge during shutdown. | Choose if cost sensitivity outweighs need for lowest IQ or fastest discharge. |
| MCP1700T-1002E/MB | 1.0-V fixed output, 1.6-μA IQ, but only 250-mA max output and lower PSRR (55 dB @ 100 Hz); SOT-23-5 package. | Larger footprint and lower noise rejection limit use in high-performance RF sections. | Select for ultra-low-IQ applications where output current demand is ≤250 mA and board space is not constrained. |

FAQ
What is the maximum input voltage rating for TLV70710DQNT?
The absolute maximum input voltage for TLV70710DQNT is 6.0 V, but the recommended operating range is 2.0 V to 5.5 V. Exceeding 5.5 V may trigger overvoltage stress conditions and reduce reliability. Operation within the recommended range ensures full specification compliance across temperature and load conditions for TLV70710DQNT.
Does TLV70710DQNT include thermal shutdown protection?
Yes, TLV70710DQNT integrates thermal shutdown protection that activates at approximately 150°C junction temperature. When triggered, the device disables the pass transistor and remains off until the die cools below the hysteresis threshold (~130°C). This safeguard prevents permanent damage during sustained overload or poor heatsinking, and is fully specified in the TLV70710DQNT datasheet.
Can TLV70710DQNT operate without any output load?
Yes, TLV70710DQNT regulates to its specified 1.0-V output accuracy even with zero load current. This feature simplifies design in systems where certain rails may be inactive for extended periods, eliminating the need for dummy loads or complex enable sequencing. The device maintains stability and accuracy across the full 0–200 mA output range, including no-load conditions.
What is the minimum output capacitor required for TLV70710DQNT stability?
TLV70710DQNT is stable with an effective output capacitance of 0.1 μF or greater. This value accounts for bias and temperature derating-so a 0.1-μF rated X5R or X7R ceramic capacitor is typically sufficient. Larger values (e.g., 1.0 μF) improve transient response but are not required for basic stability per the TLV70710DQNT specification.
Is TLV70710DQNT pin-compatible with other variants in the TLV707 family?
Yes, all TLV707 and TLV707P variants in the DQN (X2SON-4) package-including TLV70710DQNT-share identical pinout (IN, GND, EN, OUT), footprint, and thermal pad layout. Voltage variants (e.g., TLV70712DQNT, TLV70718DQNT) and P-series versions (e.g., TLV70710PDQNT) are mechanically interchangeable, though functional differences (e.g., pulldown) must be verified for each application.
