Product details
Overview
TLV70726PDQNR from Texas Instruments is a 200-mA, low-quiescent-current (25 μA), low-noise LDO regulator with 2.6 V fixed output voltage, 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 supply design in space-constrained portable electronics.
For engineers reviewing the TLV70726PDQNR datasheet, TLV70726PDQNR pinout, TLV70726PDQNR application, or TLV70726PDQNR equivalent, this page provides verified technical context, package-validated pin functions, real-world application use cases, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The TLV70726PDQNR integrates a PMOS pass transistor with thermal shutdown and overcurrent protection, supporting operation across –40°C to +125°C junction temperature. Its enable logic requires ≥0.9 V to activate and ≤0.4 V to enter shutdown, drawing only 1 μA in that state.
This device achieves 65 mV dropout at 30 mA (VOUT = 2.6 V) and maintains 0.5% output accuracy without load. The TLV707P variant - which TLV70726PDQNR belongs to - includes an internal 120-Ω active pulldown circuit for rapid output discharge during shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.6 V ±0.5% - ensures precise biasing for 2.6 V–tolerant logic and RF subsystems. |
| Max Output Current | 200 mA - supports moderate-power sensors, audio codecs, and MCU peripherals. |
| Quiescent Current | 25 μA - extends battery life in always-on wearable and IoT edge nodes. |
| PSRR @ 100 Hz | 70 dB - suppresses low-frequency noise from switching power supplies feeding the LDO input. |
| Dropout Voltage | 65 mV @ 30 mA - enables regulation from 2.665 V input, critical for single-cell Li-ion or Li-poly systems. |
| Stability Capacitance | 0.1 μF min - allows use of small-footprint X5R/X7R ceramics, reducing PCB area and BOM cost. |
| Shutdown Current | 1 μA - minimizes leakage in deep-sleep modes of portable devices. |
Pinout & Package
TLV70726PDQNR is housed in a 1.0 mm × 1.0 mm DQN (X2SON-4) package with wettable flank leads and an exposed thermal pad. This ultra-compact, thermally enhanced package supports high-density layout in handheld and wearable form factors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Regulated output | Delivers stable 2.6 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 current and internal bandgap reference; connects to thermal pad. |
| EN (Pin 3) | Enable control | Active-high logic input; ≥0.9 V enables regulation, ≤0.4 V disables with 120-Ω pulldown on TLV707P. |
| IN (Pin 4) | Input supply | Accepts 2.0–5.5 V; requires local 1-μF ceramic decoupling to GND for optimal transient immunity. |
Key Features
| Feature | Design Value |
|---|---|
| 0.5% DC output accuracy | Ensures reliable operation of voltage-sensitive analog circuits and precision ADC references without calibration. |
| 70 dB PSRR at 100 Hz | Rejects ripple from upstream DC/DC converters, preserving signal integrity in RF front-ends and audio paths. |
| 0.1 μF minimum COUT | Enables use of 0402/0201 capacitors, reducing footprint by >50% vs. traditional 1-μF requirements. |
| 120-Ω active pulldown (TLV707P) | Drains output charge rapidly during disable, preventing floating states in multi-rail sequencing or hot-swap scenarios. |
| Thermal shutdown + current limit | Protects against sustained overload or ambient overheating without external circuitry, improving system robustness. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL720F2605PDBVR | 200 mA, 2.6 V fixed, 25 μA IQ, but uses SOT-23-5 package (2.9 mm × 1.6 mm) and lacks active pulldown. | No integrated output discharge; requires external pulldown resistor for controlled shutdown sequencing. | Select when board layout allows larger footprint and pulldown is managed externally. |
| MCP1700T-2602E/TT | 250 mA, 2.6 V fixed, 1.6 μA IQ, SOT-23-3 package; no enable pin or thermal shutdown. | Unregulated shutdown behavior and no overtemperature protection limit use in thermally demanding environments. | Select only for ultra-low-IQ, non-critical applications where enable control and safety features are unnecessary. |
Compared with TPL720F2605PDBVR and MCP1700T-2602E/TT, TLV70726PDQNR uniquely combines ultra-small DQN packaging, guaranteed 0.5% accuracy, active pulldown, and full protection features - making it optimal for space- and reliability-constrained portable designs.

FAQ
What is the output voltage tolerance of TLV70726PDQNR over temperature and load?
TLV70726PDQNR maintains ±0.5% DC output accuracy across –40°C to +125°C junction temperature and 0–200 mA load range. This is verified per TI's Electrical Characteristics table, with typical deviation under 10 mV even at full load and extreme temperatures.
Does TLV70726PDQNR require an external pull-up on the EN pin?
No - TLV70726PDQNR does not require an external pull-up on EN. Its enable threshold is 0.9 V (min) for activation and 0.4 V (max) for shutdown. When unused, EN may be directly tied to IN to maintain permanent operation, as specified in the Functional Block Diagram and Pin Functions table.
Can TLV70726PDQNR operate with a 0.1 μF output capacitor in all conditions?
Yes - TLV70726PDQNR is explicitly characterized and guaranteed stable with ≥0.1 μF effective output capacitance, including derating due to bias voltage and temperature. This applies across the full operating range (–40°C to +125°C, 2.0–5.5 V input, 0–200 mA load), per Section 6.5 and 8.2.2.1 of the datasheet.
What is the purpose of the 120-Ω pulldown resistor in TLV70726PDQNR?
The 120-Ω internal pulldown in TLV70726PDQNR (a TLV707P-series part) actively discharges the OUT pin during shutdown, preventing floating voltages that could cause latch-up or unintended biasing in downstream circuitry. Its time constant depends on load resistance and COUT, per Equation 1 in the datasheet.
Is TLV70726PDQNR compatible with ceramic capacitors having high DC bias derating?
Yes - TLV70726PDQNR's 0.1 μF stability requirement refers to *effective* capacitance under operating bias and temperature. It supports X5R/X7R ceramics even with >50% DC bias derating, as long as the net capacitance seen at OUT remains ≥0.1 μF - enabling smaller, lower-cost capacitors in compact layouts.
