Product details
Overview
TLV70718DQNR from Texas Instruments is a 200-mA, low-quiescent-current (25 µA), low-noise (45 µVRMS) LDO regulator delivering 1.8 V output with ±0.5% DC accuracy and 325 mV dropout at 150 mA load. It operates from 2.0 V to 5.5 V input and features thermal shutdown, overcurrent protection, and stable operation with ≥0.1 µF ceramic output capacitance - ideal for powering RF-sensitive subsystems in compact portable electronics.
For engineers reviewing the TLV70718DQNR datasheet, TLV70718DQNR pinout, TLV70718DQNR application, or TLV70718DQNR equivalent, key selection criteria include ultra-low IQ for battery runtime, high PSRR (70 dB @ 100 Hz) for noise-sensitive analog/RF rails, minimal output capacitor requirement (0.1 µF), and 1-mm × 1-mm X2SON package for space-constrained designs.
Technical Context
The TLV70718DQNR uses a PMOS pass transistor architecture enabling low dropout and reverse-voltage tolerance via its intrinsic body diode. Its internal bandgap reference and error amplifier deliver tight regulation across –40°C to +125°C junction temperature, with no load required for specified accuracy.
It implements active-high enable logic (VIH = 0.9 V, VIL = 0.4 V) compatible with low-voltage GPIOs, and enters 1-µA shutdown mode when EN < 0.4 V. Unlike the TLV707P variant, TLV70718DQNR lacks active pulldown circuitry - output discharge relies on external load or pull-down.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8 V ±0.5% - ensures stable core voltage for 1.8-V logic, memory, and RF ICs without external feedback. |
| Max Output Current | 200 mA - supports moderate-power peripherals like Bluetooth radios, sensors, and display drivers. |
| Quiescent Current | 25 µA - extends battery life in always-on or low-duty-cycle portable devices (e.g., wearables, remote controls). |
| PSRR | 70 dB @ 100 Hz, 50 dB @ 1 MHz - suppresses switching noise from DC/DC converters feeding the LDO input rail. |
| Dropout Voltage | 325 mV @ 150 mA - enables operation from single-cell Li-ion (3.0 V min) or two-cell alkaline (3.2 V min) with margin. |
| Output Noise | 45 µVRMS (100 Hz–100 kHz) - meets low-noise requirements for ADC references, RF synthesizers, and audio codecs. |
| Stability Capacitance | ≥0.1 µF ceramic - allows use of small, low-cost, bias-stable capacitors (e.g., 0402 X5R) without ESR constraints. |
Pinout & Package
TLV70718DQNR is housed in a 4-pin, 1.0 mm × 1.0 mm DQN (X2SON) package with wettable flanks, optimized for automated optical inspection (AOI) and thermal performance in dense PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Regulated output | Delivers stable 1.8 V; requires ≥0.1 µF ceramic capacitor to GND for stability and transient response. |
| GND (Pin 2) | Ground reference | Low-impedance return path; connects to thermal pad for enhanced heat dissipation (RθJB = 159.4°C/W). |
| IN (Pin 4) | Input supply | Accepts 2.0–5.5 V; place 1-µF ceramic capacitor close to this pin to minimize input ripple and improve transient immunity. |
| EN (Pin 3) | Enable control | Active-high logic input; drives regulator ON above 0.9 V, OFF below 0.4 V; draws only 0.01 µA leakage current. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 25 µA enables >1-year battery life in coin-cell-powered IoT sensors with 10-sec wake-up intervals. |
| High PSRR at low frequency | 70 dB rejection at 100 Hz prevents coupling of low-frequency power supply ripple into noise-sensitive analog circuits. |
| Minimal output capacitance | Stable with 0.1 µF effective capacitance - reduces BOM cost and board area versus traditional 2.2–10 µF LDO solutions. |
| Wide input voltage range | 2.0 V to 5.5 V supports direct connection to USB, Li-ion, or multi-cell battery sources without pre-regulation. |
| Robust protection suite | Integrated thermal shutdown and current limiting prevent damage during short-circuit or overload conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC70718DQNR | Same 1.8-V output, but higher IQ (45 µA) and lower PSRR (60 dB @ 100 Hz); no thermal shutdown. | Suitable only for non-safety-critical, low-transient applications with relaxed noise specs. | Select only if TI's TLV70718DQNR is unavailable and system thermal margin exceeds 20°C. |
| MCP1700T-1802E/MB | 1.8-V fixed output, 1.6-µA IQ, but limited 250-mA max output and 65-dB PSRR @ 100 Hz; SOT-23-3 package. | Better for ultra-low-power microcontroller rails, not RF or high-transient loads. | Prefer for sub-100-mA logic rails where board space permits larger SOT-23; avoid for 150-mA+ or RF-sensitive use cases. |
Compared with TLC70718DQNR and MCP1700T-1802E/MB, TLV70718DQNR uniquely balances ultra-low IQ (25 µA), high PSRR (70 dB), full protection features, and 200-mA capability in a 1-mm² package - making it optimal for space- and noise-constrained portable RF systems.

FAQ
What is the minimum input voltage required for TLV70718DQNR to regulate 1.8 V at 150 mA?
The TLV70718DQNR requires a minimum input voltage of 2.125 V to maintain regulation at 150 mA, calculated as VOUT + VDO = 1.8 V + 325 mV. This headroom enables reliable operation from partially discharged single-cell Li-ion batteries (≥3.0 V nominal) and dual-cell alkaline sources.
Does TLV70718DQNR include an active output pulldown circuit?
No, TLV70718DQNR does not include an active pulldown circuit. That feature is exclusive to the TLV707P variant (e.g., TLV70718PDQNR), which integrates a 120-Ω internal discharge path. TLV70718DQNR relies on external load or pull-down resistors for output discharge during shutdown.
Can TLV70718DQNR operate without any output load?
Yes, TLV70718DQNR regulates to its specified ±0.5% accuracy with zero output load. This capability simplifies power sequencing in systems where certain rails may be unpopulated or disconnected during test or low-power modes.
What is the maximum allowable input voltage for TLV70718DQNR?
The absolute maximum input voltage for TLV70718DQNR is 6.0 V. However, the recommended operating range is 2.0 V to 5.5 V. Exceeding 5.5 V risks exceeding thermal limits or violating safe operating area, especially at high ambient temperatures.
Is TLV70718DQNR stable with a 0.1 µF X7R ceramic capacitor?
Yes, TLV70718DQNR is explicitly characterized and guaranteed stable with ≥0.1 µF effective output capacitance, including standard 0.1 µF X7R ceramics. The device's internal compensation eliminates ESR dependency, allowing use of small-case, bias-stable dielectrics without risk of oscillation.
