Texas Instruments TLV76750DRVT

Overview

TLV76750DRVT 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 5.0 V output with ±1% accuracy over load and temperature, 50 µA typical quiescent current, and stable operation with 1-µF ceramic output capacitors. It serves as a post-regulator for MCU core/logic rails in space-constrained industrial control and embedded systems.

For engineers reviewing the TLV76750DRVT datasheet, TLV76750DRVT pinout, TLV76750DRVT application, or TLV76750DRVT equivalent, key selection criteria include dropout voltage at 1 A (≤1.4 V), high PSRR (70 dB @ 1 kHz), thermal shutdown (180°C), enable logic thresholds (VEN(HIGH) ≥ 1.2 V), and compatibility with low-ESR ceramic capacitors down to 1 µF.

Technical Context

The TLV76750DRVT implements a CMOS-based LDO architecture with internal 0.8-V reference and error amplifier, supporting fixed-output operation without external feedback components. Its foldback current limiting activates at 50% of nominal output voltage (2.5 V), transitioning from brickwall (1.1–1.6 A) to short-circuit mode (150–250 mA).

Thermal protection includes junction shutdown at 180°C and reset at 160°C, while undervoltage lockout engages below 2.2 V (rising) with 130-mV hysteresis. The device features an internal EN pullup (~400 nA), enabling direct VIN tie or floating EN for default-on operation, and active output pulldown (1.2 mA) during disable.

FAQ

What is the maximum input voltage rating for TLV76750DRVT?

The absolute maximum input voltage for TLV76750DRVT is 18 V, but the recommended operating range is 2.5 V to 16 V. Exceeding 16 V may trigger internal UVLO or reduce long-term reliability, and operation above 18 V risks permanent damage per the Absolute Maximum Ratings table.

Does TLV76750DRVT require external feedback resistors to set its output voltage?

No, TLV76750DRVT is a fixed-output variant and does not require external feedback resistors. Its internal resistor network sets the output to 5.0 V; the FB pin is internally connected and must remain unconnected in the schematic.

Can TLV76750DRVT operate with only a 1-µF ceramic output capacitor?

Yes, TLV76750DRVT is explicitly characterized for stability with a minimum 1-µF ceramic output capacitor (ESR ≤ 500 mΩ). Using smaller or higher-ESR capacitors may cause oscillation or poor transient response.

What is the thermal shutdown behavior of TLV76750DRVT?

TLV76750DRVT shuts down at 180°C junction temperature and resets automatically at 160°C. During thermal shutdown, the output is disabled and the EN pin remains functional-allowing external logic to force recovery or initiate safe shutdown sequences.

Is the EN pin of TLV76750DRVT pulled up internally?

Yes, TLV76750DRVT includes an internal ~400-nA pullup on the EN pin. This allows the device to power up automatically when EN is left floating, simplifying design in always-on applications without requiring an external pullup resistor.
