Product details
Overview
TLV70736DQNT from Texas Instruments is a 200-mA, low-quiescent-current (25 µA), low-noise LDO regulator with 3.6 V fixed output voltage, 0.5% DC accuracy, and 70 dB PSRR at 100 Hz - designed for power-sensitive portable electronics such as smartphones, wearables, and WLAN add-on cards.
For engineers reviewing the TLV70736DQNT datasheet, TLV70736DQNT pinout, TLV70736DQNT application, or TLV70736DQNT equivalent, key selection criteria include dropout voltage (220 mV @ 150 mA, 3.6 V output), stability with 0.1 µF output capacitance, thermal/overcurrent protection, and enable-pin logic thresholds (VIH = 0.9 V, VIL = 0.4 V).
Technical Context
The TLV70736DQNT employs a PMOS pass transistor architecture enabling ultra-low dropout and high PSRR across 100 Hz–1 MHz. Its internal bandgap reference and error amplifier deliver 0.5% output accuracy over –40°C to +125°C junction temperature, with no load regulation capability.
It integrates active-high enable control with shutdown current of 1 µA and features built-in thermal shutdown and foldback current limiting. The device operates with input voltages from 2.0 V to 5.5 V and supports stable regulation using only 0.1 µF effective output capacitance - enabling use of small-footprint, bias-voltage-derated ceramic capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.6 V ±0.5% - ensures precise rail generation for 3.3 V–3.6 V logic and RF subsystems. |
| Max Output Current | 200 mA - sufficient for powering baseband processors, sensors, and low-power wireless transceivers. |
| Quiescent Current | 25 µA - minimizes battery drain in always-on wearable and IoT standby modes. |
| PSRR | 70 dB @ 100 Hz, 50 dB @ 1 MHz - suppresses switching noise from DC/DC converters feeding the LDO input. |
| Dropout Voltage | 220 mV @ 150 mA - enables operation from single-cell Li-ion (3.0 V min) while maintaining regulation. |
| Stability Capacitance | 0.1 µF effective - allows use of compact 0402/0201 X5R/X7R ceramics without ESR constraints. |
| Enable Threshold | VIH = 0.9 V, VIL = 0.4 V - compatible with low-voltage GPIOs (1.2 V/1.8 V I/O domains) without level-shifting. |
Pinout & Package
TLV70736DQNT 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 bottom enhances PCB heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Regulated output | Delivers stable 3.6 V to load; requires ≥0.1 µF ceramic capacitor to GND for stability. |
| GND (Pin 2) | Ground reference | Return path for IN, OUT, and internal circuitry; must be low-impedance connection to PCB ground plane. |
| EN (Pin 3) | Enable control input | Active-high logic: ≥0.9 V enables regulation; ≤0.4 V disables output and reduces IQ to 1 µA. |
| IN (Pin 4) | Input supply | Accepts 2.0–5.5 V input; requires local 1 µF ceramic bypass capacitor to GND for transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise regulation | 45 µVRMS output noise (100 Hz–100 kHz) - preserves signal integrity in RF front-ends and ADC references. |
| Ultra-low IQ | 25 µA quiescent current - extends battery life in multi-week standby applications. |
| Robust protection | Thermal shutdown + foldback current limit - prevents damage during short-circuit or overload events. |
| Small-footprint stability | Stable with 0.1 µF effective COUT - enables space-constrained designs using 0201/0402 capacitors. |
| Wide input range | 2.0 V to 5.5 V operation - supports direct connection to Li-ion, USB, or buck converter outputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLS850F33TAV50 | Automotive-grade AEC-Q100 qualified; higher IQ (45 µA); 3.3 V output only | Designed for automotive infotainment power rails; not optimized for portable battery life | Select when automotive qualification and higher temperature rating (–40°C to +150°C) are required |
| MCP1700T-3602E/TT | 250 mA max output; 1.6 µA IQ; no enable pin; 3.6 V fixed output | Lacks EN control and thermal shutdown; intended for ultra-low-power always-on microcontrollers | Select when minimal IQ dominates design priority and enable functionality is unnecessary |
Compared with TLS850F33TAV50 and MCP1700T-3602E/TT, TLV70736DQNT uniquely balances ultra-low IQ (25 µA), integrated enable control, full protection suite, and 3.6 V precision output - making it optimal for consumer portable systems requiring both efficiency and robustness.

FAQ
What is the maximum input voltage rating for TLV70736DQNT?
The absolute maximum input voltage for TLV70736DQNT is 6.0 V. However, the recommended operating range is 2.0 V to 5.5 V. Exceeding 6.0 V may cause permanent damage. Operation above 5.5 V is not guaranteed per specifications and risks violating thermal and electrical limits defined in the datasheet.
Does TLV70736DQNT require an external pull-up resistor on the EN pin?
No, TLV70736DQNT does not require an external pull-up resistor on the EN pin. The device has an internal pull-down, and EN is active-high with VIH = 0.9 V minimum. When enable functionality is not needed, EN can be directly tied to IN. External pull-up is only necessary if system-level reset sequencing mandates controlled startup timing.
Can TLV70736DQNT operate with zero load current?
Yes, TLV70736DQNT regulates to specified accuracy (±0.5%) with no output load. This is confirmed in the datasheet's Electrical Characteristics table under "DC output accuracy" test condition: "VOUT ≥ 0.85 V, IOUT = 0 mA". Ground current remains at 25 µA typical under no-load conditions.
What is the thermal resistance (RθJA) of TLV70736DQNT in its DQN package?
The junction-to-ambient thermal resistance (RθJA) for TLV70736DQNT in the 1-mm × 1-mm DQN (X2SON-4) package is 208.1°C/W, measured on a standard JEDEC 2S2P test board. This value assumes proper PCB copper pour under the thermal pad; actual RθJA improves significantly with enhanced heatsinking via multiple vias to inner ground planes.
Is TLV70736DQNT pin-compatible with other TLV707 variants?
Yes, all TLV707 and TLV707P variants in the DQN (X2SON-4) package - including TLV70736DQNT - share identical pinout (IN, GND, EN, OUT), footprint, and thermal pad layout. Voltage variants (e.g., TLV70712DQNT, TLV70728DQNT) and P-version (TLV70736PDQNT) are mechanically interchangeable, though functional differences (e.g., pulldown resistor in P-version) must be verified per application.
