Product details
Overview
TLV707185DQNR from Texas Instruments is a 200-mA, low-quiescent-current (25 µA), low-noise (45 µVRMS) LDO regulator with fixed 1.85 V output, 0.5% DC accuracy, and 70 dB PSRR at 100 Hz. It operates from 2.0 V to 5.5 V input and delivers stable regulation down to 0.1 µF output capacitance - enabling compact, cost-effective power delivery in space-constrained portable electronics.
For engineers reviewing the TLV707185DQNR datasheet, TLV707185DQNR pinout, TLV707185DQNR application, or TLV707185DQNR equivalent, key selection criteria include dropout voltage (220 mV @ 150 mA for 1.85 V output), thermal shutdown/overcurrent protection, active-high enable with 0.9 V logic threshold, and X2SON-4 package compatibility with high-density PCB layouts.
Technical Context
The TLV707185DQNR uses a PMOS pass transistor architecture delivering ultra-low quiescent current (25 µA typical) while maintaining fast load transient response and high PSRR across 100 Hz–1 MHz. Its internal bandgap reference and error amplifier ensure ±1.5% total DC accuracy over –40°C to +125°C junction temperature.
Unlike standard LDOs, it achieves stability with only 0.1 µF effective output capacitance - verified across bias voltage and temperature derating - and includes integrated thermal shutdown and current limiting (240–450 mA). The TLV707P variant adds an internal 120-Ω pulldown resistor; however, TLV707185DQNR is the base TLV707 version without pulldown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.85 V - eliminates external feedback network; supports 1.8-V logic rails with margin. |
| Max Output Current | 200 mA - sufficient for RF transceivers, sensor interfaces, and MCU core supplies in portable devices. |
| Quiescent Current | 25 µA - enables >1-year battery life in always-on wearable sensors with 200-mAh coin cells. |
| PSRR @ 100 Hz | 70 dB - suppresses switching noise from adjacent DC/DC converters feeding shared input rails. |
| Dropout Voltage | 220 mV @ 150 mA - allows operation from 2.075 V input, compatible with single-cell Li-ion (2.7–4.2 V) and LiFePO₄ (2.0–3.6 V) batteries. |
| Output Noise | 45 µVRMS (100 Hz–100 kHz) - meets low-noise requirements for ADC references and RF synthesizer VCO supplies. |
| Accuracy | ±1.5% over temp/load - ensures reliable operation of 1.8-V I/O interfaces without margining overhead. |
Pinout & Package
TLV707185DQNR is housed in a 1.0 mm × 1.0 mm DQN (X2SON-4) package with wettable flank terminations for automated optical inspection. Thermal pad on underside improves power dissipation in high-ambient environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Regulated output | Delivers 1.85 V; requires ≥0.1 µF ceramic capacitor to ground for stability; no ESR dependency. |
| GND (Pin 2) | Ground reference | Low-impedance return path; connects to thermal pad for enhanced thermal performance. |
| EN (Pin 3) | Enable control | Active-high logic input; enables regulator when ≥0.9 V; disables to 1 µA shutdown current when ≤0.4 V. |
| 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 response. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 25 µA quiescent current enables multi-year operation in battery-powered IoT endpoints. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL720185PDQNR | Lower IQ (2.5 µA), same 1.85 V output, but requires minimum 1 µF COUT and lacks EN pin. | No enable control; unsuitable for dynamic power gating or sequencing-critical systems. | Select when ultra-low standby current is primary requirement and enable functionality is unnecessary. |
| MCP1700T-1802E/MB | 100-mA rating, 2 µA IQ, SOT-23-3 package; no EN pin; ±2% accuracy. | Limited output current and accuracy; not suitable for 150-mA RF loads or precision analog rails. | Choose only for low-cost, low-current auxiliary rails where size and accuracy are secondary. |
Compared with TPL720185PDQNR and MCP1700T-1802E/MB, TLV707185DQNR uniquely balances 200-mA capability, 25-µA IQ, EN control, and 0.1-µF stability - making it optimal for space-constrained, battery-sensitive RF and sensor subsystems requiring flexible power management.

FAQ
What is the maximum input voltage rating for TLV707185DQNR?
The absolute maximum input voltage for TLV707185DQNR is 6.0 V. However, the recommended operating range is 2.0 V to 5.5 V. Exceeding 6.0 V risks permanent damage; operation above 5.5 V may degrade reliability or violate thermal limits even within datasheet current limits.
Does TLV707185DQNR include an internal pull-down resistor on the OUT pin?
No, TLV707185DQNR does not include an internal pull-down resistor. That feature is exclusive to the TLV707P variant (e.g., TLV707185PDQNR). TLV707185DQNR is the base TLV707 version and relies on external circuitry for output discharge during shutdown.
Can TLV707185DQNR operate with a 0.1 µF ceramic capacitor?
Yes, TLV707185DQNR is explicitly characterized and guaranteed stable with an effective output capacitance of 0.1 µF or greater - including under bias voltage and temperature derating. This is confirmed in Section 6.5 and Figure 6-2 of the official TI datasheet SBVS153G.
What is the typical startup time for TLV707185DQNR?
The typical startup time for TLV707185DQNR is 100 µs, defined as the time from EN rising above 0.9 V to VOUT reaching 98% of 1.85 V, measured with COUT = 1.0 µF and IOUT = 150 mA. Startup time scales linearly with output capacitance and is unaffected by load below 150 mA.
Is TLV707185DQNR RoHS-compliant and lead-free?
Yes, TLV707185DQNR is RoHS-compliant and lead-free. It meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) and is qualified for Pb-free reflow soldering per IPC/JEDEC J-STD-020. Full compliance documentation is available in TI's official product folder and packaging reports.
