Texas Instruments TLV76708DRVR

Overview

TLV76708DRVR 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 0.8 V output with ±1% accuracy over load and temperature, 50 µA typical quiescent current, and stable operation with 1-µF ceramic output capacitors - used to power low-voltage microcontrollers and processors in space-constrained industrial control modules.

For engineers reviewing the TLV76708DRVR datasheet, TLV76708DRVR pinout, TLV76708DRVR application, or TLV76708DRVR equivalent, key selection criteria include dropout voltage at 1 A (≤1.4 V), high PSRR (70 dB @ 1 kHz), thermal shutdown (180°C), UVLO (2.2–2.4 V rising threshold), and compatibility with 2.5–16 V input rails in automotive and industrial embedded systems.

Technical Context

The TLV76708DRVR implements a CMOS-based LDO architecture with an internal 0.8-V reference and active-high enable control, supporting fixed-output operation without external feedback resistors. Its foldback current limiting activates at 50% of nominal output voltage (0.4 V), reducing short-circuit current to 150–250 mA depending on package.

Thermal protection includes 180°C shutdown and 160°C reset hysteresis, while undervoltage lockout prevents regulation below 2.2 V input. The device operates across –40°C to +125°C ambient, with R_θJA = 77.7°C/W in the DRV package and stable performance using only 1-µF C_OUT with ≤500 mΩ ESR.

FAQ

What is the maximum input voltage rating for TLV76708DRVR?

The TLV76708DRVR has an absolute maximum input voltage rating of 18 V, with recommended continuous operation up to 16 V. Exceeding 18 V risks permanent damage. This 16-V operating limit enables use after wide-input buck converters and in 12-V automotive systems with transient tolerance.

Does TLV76708DRVR require external feedback resistors for its 0.8-V output?

No, TLV76708DRVR is a fixed-output variant - its 0.8-V regulation is achieved using internal feedback resistors. Pin 2 (FB) is internally connected and must be tied to OUT per TI's layout guidance; no external resistors are needed or permitted.

What is the thermal shutdown behavior of TLV76708DRVR?

TLV76708DRVR triggers thermal shutdown at 180°C junction temperature and resets at 160°C, providing 20°C hysteresis. During shutdown, the output is disabled and the internal pulldown actively discharges V_OUT, preventing latch-up in thermally overloaded conditions.

Can TLV76708DRVR operate with a 2.5-V input while delivering 0.8-V output at full load?

Yes - at 2.5-V input, TLV76708DRVR delivers up to 800 mA while maintaining regulation. Dropout is ≤1.3 V under these conditions, leaving ~0.2 V headroom. For 1-A loads, VIN ≥ 3.0 V is required per datasheet specifications.

Is the EN pin of TLV76708DRVR compatible with 1.8-V GPIOs?

Yes - the EN pin logic-high threshold is specified at 1.2 V minimum (V_EN(HIGH)), ensuring reliable activation from standard 1.8-V digital outputs. The internal pullup also allows direct connection to VIN for always-on operation without external biasing.
