Product details
Overview
TLV76708DGNR from Texas Instruments is a 1-A, 16-V input precision linear voltage regulator in an 8-pin HVSSOP package, delivering fixed 0.8 V output with ±1% accuracy over –40°C to +125°C, 50 µA typical quiescent current, and stable operation with 1-µF ceramic output capacitance - used for powering low-voltage microcontrollers and processors in space-constrained industrial control and embedded systems.
For engineers reviewing the TLV76708DGNR datasheet, TLV76708DGNR pinout, TLV76708DGNR application, or TLV76708DGNR equivalent, key selection criteria include dropout voltage (≤1.5 V at 1 A), high PSRR (70 dB @ 1 kHz), enable logic thresholds (VEN(HIGH) ≥ 1.2 V), thermal shutdown (180°C), and compatibility with low-ESR ceramic capacitors in compact HVSSOP layouts.
Technical Context
The TLV76708DGNR implements a CMOS-based LDO architecture with internal 0.8-V reference, active-high enable with internal pullup, and foldback current limiting that transitions from brickwall (ICL = 1.1–1.6 A) to short-circuit mode (ISC = 250 mA typical) below 50% VOUT. It features undervoltage lockout (UVLO rising threshold 2.2–2.4 V) and internal output pulldown during shutdown.
Its high PSRR (>70 dB at 1 kHz, >46 dB at 1 MHz) suppresses switching noise from upstream DC/DC converters, while soft-start (500 µs typical) and reduced inrush current minimize input capacitance requirements - critical for battery-backed and always-on subsystems requiring low standby power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VOUT | Fixed 0.8 V ±1% over load, line, and temperature - ensures stable core supply for sub-1V MCUs and FPGAs. |
| IOUT Max | 1 A continuous (≥3 V input); 800 mA (2.5–3 V input) - supports moderate-power digital loads without external heatsinking. |
| VIN Range | 2.5 V to 16 V - enables direct regulation from 3.3 V, 5 V, 12 V rails or wide-input industrial supplies. |
| IQ | 50 µA typical (active), 1.5 µA typical (shutdown) - meets stringent standby power budgets in IoT and portable devices. |
| PSRR | 70 dB @ 1 kHz, 46 dB @ 1 MHz - attenuates switching ripple from buck converters, reducing need for post-regulation filtering. |
| Dropout | 0.9–1.5 V @ 1 A (DGN package) - allows operation with minimal headroom, e.g., 3.3 V IN → 0.8 V OUT at full load. |
| Thermal Shutdown | 180°C trip, 160°C reset - provides robust overtemperature protection in enclosed or high-ambient environments. |
Pinout & Package
TLV76708DGNR uses the 8-pin HVSSOP (DGN) package: 3.00 mm × 3.00 mm body, exposed thermal pad, RoHS-compliant, moisture sensitivity level 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Regulated output | Delivers fixed 0.8 V; requires local 1-µF ceramic capacitor to GND for stability. |
| 2 - FB / SNS | Feedback / Sense | In fixed version, functions as output sense (SNS); connect directly to OUT or remote load point to improve regulation accuracy. |
| 3 - NC | No connect | Not internally bonded; must be left floating or tied to GND per layout guidelines. |
| 4 - GND | Ground | Primary ground return; all GND pins (4 & 6) must be connected to low-impedance ground plane. |
| 5 - EN | Enable input | Active-high logic (VEN(HIGH) ≥ 1.2 V); internal pullup allows floating for default-enable operation. |
| 6 - GND | Ground | Second ground terminal; improves thermal and EMI performance when tied to same ground net as Pin 4. |
| 7 - NC | No connect | Not internally bonded; must be left floating or tied to GND per layout guidelines. |
| 8 - IN | Input supply | Accepts 2.5–16 V; requires 1-µF ceramic capacitor placed adjacent to IN/GND pins. |
Key Features
| Feature | Design Value |
|---|---|
| Stable with 1-µF ceramic COUT | Eliminates need for large tantalum or electrolytic capacitors - reduces board area and improves reliability. |
| Internal soft-start (500 µs) | Controls output ramp rate to prevent inrush current spikes into downstream capacitance, easing input capacitor sizing. |
| Foldback current limiting | Reduces power dissipation during short-circuit events by scaling output current as VOUT drops below 0.4 V, enhancing fault survivability. |
| High PSRR (70 dB @ 1 kHz) | Enables clean power delivery in noisy mixed-signal systems where upstream DC/DC converters operate near sensitive analog blocks. |
| Thermal shutdown with hysteresis | Auto-recovery after cooling (20°C hysteresis) prevents latch-up in transient overload conditions without system intervention. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLS850F0TESK | 500-mA rated, integrated watchdog timer, automotive AEC-Q100 qualified, 3.3-V fixed output only | Targeted for automotive body electronics; lacks 0.8-V option and adjustable capability | Choose for automotive-grade 3.3-V rail with safety monitoring; not suitable for 0.8-V core supply replacement. |
| TPS7A2008PDBVR | 1-A rated, 0.8-V fixed, 6.5-µA IQ (lower), 2-mm × 2-mm WSON-6 package, no thermal pad | Better suited for ultra-low-IQ portable designs; smaller footprint but lower thermal performance than DGN | Prefer for space-constrained battery-powered devices where thermal margin is sufficient and 60.1°C/W RθJA is acceptable. |
Compared with TLS850F0TESK and TPS7A2008PDBVR, TLV76708DGNR offers superior thermal performance (60.1°C/W RθJA vs. ~100°C/W for WSON), higher PSRR at 1 MHz, and proven stability with minimal 1-µF output capacitance - making it optimal for industrial and high-ambient applications demanding robustness and noise immunity.

FAQ
What is the output voltage tolerance of TLV76708DGNR over temperature and load?
The TLV76708DGNR maintains ±1% output voltage accuracy across –40°C to +125°C junction temperature and full load range (1 mA to 1 A), as specified in the Electrical Characteristics table under "Output accuracy over temperature." This applies to both line and load regulation, ensuring consistent 0.8-V delivery for sensitive digital cores without external trimming.
Can TLV76708DGNR operate with only a 1-µF ceramic output capacitor?
Yes - TLV76708DGNR is explicitly characterized and guaranteed stable with a minimum 1-µF ceramic output capacitor (COUT), as stated in Section 6.3 Recommended Operating Conditions and Feature list. This eliminates reliance on larger, less reliable electrolytic or tantalum capacitors and simplifies layout in compact designs.
What is the maximum input voltage rating for TLV76708DGNR?
The absolute maximum input voltage for TLV76708DGNR is 18 V, but the recommended operating range is 2.5 V to 16 V per Section 6.3. Operation above 16 V risks exceeding safe operating area limits and is not supported for continuous use - design margins should maintain VIN ≤ 16 V under all conditions including transients.
Does TLV76708DGNR include thermal protection?
Yes - TLV76708DGNR integrates thermal shutdown with a trip temperature of 180°C and automatic recovery at 160°C (20°C hysteresis). This protection activates during sustained overload or poor PCB thermal design, and the device resumes normal operation once junction temperature falls below the reset threshold - no external circuitry required.
How does the enable pin (EN) function on TLV76708DGNR?
The EN pin on TLV76708DGNR is active-high with internal pullup (~400 nA), allowing it to be left floating for default-enable operation. Logic high (≥1.2 V) enables regulation; logic low (≤0.4 V) disables output and reduces quiescent current to 1.5 µA. The pin also activates internal output pulldown during disable to discharge downstream capacitance.
