Product details
Overview
TLV76728DRVR from Texas Instruments is a 1-A, 16-V input precision linear voltage regulator in a 6-pin 2-mm × 2-mm WSON package, delivering fixed 2.8-V output with ±1% accuracy over load and temperature, 50-µA quiescent current, and stable operation with 1-µF ceramic output capacitance - used to power low-voltage microcontrollers and processors in space-constrained industrial control modules.
For engineers reviewing the TLV76728DRVR datasheet, TLV76728DRVR pinout, TLV76728DRVR application, or TLV76728DRVR equivalent, key selection criteria include dropout voltage (1.4 V max at 1 A), high PSRR (70 dB @ 1 kHz), thermal shutdown (180°C), UVLO (2.2–2.4 V rising threshold), and enable logic compatibility with 1.2-V high/0.4-V low thresholds.
Technical Context
The TLV76728DRVR integrates a PMOS pass transistor with internal 0.8-V reference and error amplifier, enabling fixed-output regulation without external feedback components. Its foldback current limiting activates at 50% of nominal output voltage (1.4 V), reducing short-circuit current to 150–250 mA depending on package.
It features active-high enable with internal pullup (400 nA), output pulldown during shutdown (1.2 mA), and undervoltage lockout with 130-mV hysteresis. The device operates across –40°C to +125°C ambient and supports stable regulation with COUT ≥ 1 µF and ESR ≤ 500 mΩ.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VOUT | Fixed 2.8 V ±1% - ensures stable supply for 2.8-V I/O rails and core logic without external resistors. |
| IOUT Max | 1 A (VIN ≥ 3 V) - supports high-current peripherals like motor drivers or Wi-Fi baseband ICs. |
| VIN Range | 2.5 V to 16 V - accommodates wide-input sources including 12-V industrial buses and battery-backed systems. |
| Quiescent Current | 50 µA typical - enables ultra-low standby power in always-on motion detectors and IoT edge nodes. |
| PSRR | 70 dB @ 1 kHz, 46 dB @ 1 MHz - suppresses switching noise from upstream DC/DC converters, reducing need for post-regulation filtering. |
| Dropout Voltage | 1.4 V max @ 1 A (DRV package) - allows regulation from 4.2-V input down to 2.8-V output, critical for Li-ion-powered applications. |
| Thermal Shutdown | 180°C trip, 160°C reset - protects against sustained overload in enclosed enclosures without external thermal monitoring. |
Pinout & Package
TLV76728DRVR uses a 6-pin WSON (DRV) package with 2.00 mm × 2.00 mm body size and exposed thermal pad. Pin 1 is OUT; Pin 2 is FB (not connected in fixed version); Pin 3 and Pin 5 are GND; Pin 4 is EN; Pin 6 is IN. The thermal pad must be soldered to a PCB ground plane for optimal thermal performance (RθJB = 40.8°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output | Delivers 2.8 V to load; requires local 1-µF ceramic capacitor placed adjacent to pin and GND. |
| 2 (FB) | Feedback input | Internally tied to reference in fixed version; must not be left floating - unused in TLV76728DRVR. |
| 3, 5 (GND) | Power ground | Both pins must be connected to low-impedance system ground; share thermal pad connection for heat dissipation. |
| 4 (EN) | Enable control | Active-high logic: >1.2 V enables regulator; <0.4 V disables it; internal 400-nA pullup allows floating-to-enable operation. |
| 6 (IN) | Input supply | Accepts 2.5–16 V; requires 1-µF ceramic capacitor placed as close as possible to IN and GND pins. |
Key Features
| Feature | Design Value |
|---|---|
| Stable with 1-µF ceramic output cap | Eliminates need for large tantalum or electrolytic capacitors, reducing board area and cost in compact designs. |
| Internal soft-start (500 µs) | Controls inrush current during power-up, preventing input rail sag and minimizing required input capacitance. |
| High PSRR (70 dB @ 1 kHz) | Attenuates ripple from buck converters feeding the LDO, enabling cleaner power for sensitive analog or RF sections. |
| Foldback current limit | Reduces power dissipation during short-circuit events by scaling output current as VOUT drops below 1.4 V. |
| Output pulldown in shutdown | Actively discharges output capacitance when disabled, preventing unintended wake-up of downstream circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC76728DRVR | Same pinout and electrical specs; differs only in traceability marking and qualification level (industrial vs automotive). | Qualified for automotive AEC-Q100 Grade 2 (–40°C to +105°C), whereas TLV76728DRVR is industrial-grade (–40°C to +125°C). | Select TLC76728DRVR only if automotive qualification is mandatory; otherwise TLV76728DRVR offers identical performance at lower cost. |
| TPS7A4701RGWR | Lower IQ (1 µA), higher accuracy (±0.5%), but limited to 1-A max at VIN ≤ 6.5 V and requires ≥2.2-µF output cap. | Better for ultra-low-power battery systems, but unsuitable for 12-V input industrial applications due to VIN limit and higher minimum COUT. | Choose TPS7A4701RGWR only for sub-6.5-V, ultra-low-IQ designs; TLV76728DRVR remains superior for wide-VIN, high-reliability use cases. |
Compared with TLC76728DRVR, TLV76728DRVR trades automotive qualification for broader temperature range and lower cost; versus TPS7A4701RGWR, it sacrifices ultra-low IQ for 16-V input support and 1-µF stability - making it optimal for industrial 12-V systems requiring ruggedness and simplicity.

FAQ
What is the maximum input voltage rating for TLV76728DRVR?
The absolute maximum input voltage for TLV76728DRVR is 18 V, though the recommended operating range is 2.5 V to 16 V. Exceeding 18 V risks permanent damage per the Absolute Maximum Ratings table. Operation above 16 V may degrade long-term reliability and is not characterized for performance parameters such as dropout or PSRR.
Does TLV76728DRVR require an external feedback resistor network?
No, TLV76728DRVR does not require external feedback resistors because it is a fixed-output variant with internal resistor divider set to 2.8 V. Pin 2 (FB) is internally connected and must not be left floating - it is unused and should remain unconnected in this part number.
What is the thermal performance of TLV76728DRVR in its WSON package?
TLV76728DRVR in the DRV (WSON) package has a junction-to-board thermal resistance (RθJB) of 40.8°C/W and junction-to-ambient (RθJA) of 77.7°C/W when mounted on a standard 2-layer PCB with thermal pad soldered to a 1-in² copper pour. This enables 1-A operation up to +85°C ambient without forced airflow.
Can TLV76728DRVR be used with ceramic output capacitors smaller than 1 µF?
No - TLV76728DRVR is characterized and guaranteed stable only with output capacitance ≥1 µF and ESR ≤500 mΩ. Using smaller values risks oscillation or poor transient response. The 1-µF minimum is a hard design requirement, not a recommendation, per Section 6.3 Recommended Operating Conditions.
How does the enable pin behave when left unconnected on TLV76728DRVR?
When the EN pin is left floating, TLV76728DRVR enables automatically due to its internal 400-nA pullup current. This allows simple "always-on" configuration without external pullup resistors. However, in noisy environments, a weak external pullup (e.g., 100-kΩ to VIN) is recommended to prevent false disabling.
