Texas Instruments TLV76750DGNR

Overview

TLV76750DGNR from Texas Instruments is a 1-A, 16-V input precision linear voltage regulator in an 8-pin HVSSOP 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 - used to power low-voltage MCUs and processors in space-constrained industrial control boards.

For engineers reviewing the TLV76750DGNR datasheet, TLV76750DGNR pinout, TLV76750DGNR application, or TLV76750DGNR equivalent, key selection criteria include dropout voltage (≤1.5 V at 1 A), high PSRR (70 dB @ 1 kHz), thermal shutdown (180°C), enable logic thresholds (VEN(HIGH) ≥ 1.2 V), and compatibility with 2.5–16 V input rails in automotive-grade ambient ranges (–40°C to +125°C).

Technical Context

The TLV76750DGNR implements a CMOS-based LDO architecture with internal 0.8-V reference, foldback current limiting, and active pulldown during shutdown. Its fixed-output version uses an internal resistor divider to set VOUT = 5.0 V and replaces FB with SNS for remote sensing capability.

It features undervoltage lockout (UVLO rising threshold 2.2–2.4 V), thermal shutdown with hysteresis (180°C trip / 160°C reset), and soft-start (500 µs typical) to limit inrush current - enabling robust start-up into large capacitive loads without external sequencing.

Key Specifications

Pinout & Package

TLV76750DGNR is housed in an 8-pin HVSSOP (DGN) package (3.0 mm × 3.0 mm, 0.65 mm pitch) with exposed thermal pad. The package supports high-power dissipation (R_θJA = 60.1°C/W) and requires connection of the thermal pad to a large-area ground plane for optimal thermal performance.

FAQ

What is the maximum input voltage rating for TLV76750DGNR?

The absolute maximum input voltage for TLV76750DGNR is 18 V, but the recommended operating range is 2.5 V to 16 V. Operation above 16 V risks exceeding safe power dissipation limits and may trigger thermal shutdown. The device includes UVLO that disables output below ~2.2 V, preventing erratic behavior during brownout conditions.

Does TLV76750DGNR require external components for stability?

No - TLV76750DGNR is stable with only a 1-µF ceramic output capacitor and a 1-µF input capacitor. Unlike many LDOs, it does not require ESR-tuned capacitors or feed-forward networks. The SNS pin (Pin 2) must be connected directly to the output or remote load node; leaving it floating will cause regulation failure.

How does the enable pin (EN) function on TLV76750DGNR?

The EN pin is active-high with logic thresholds of V_EN(HIGH) ≥ 1.2 V and V_EN(LOW) ≤ 0.4 V. It features an internal pullup (~400 nA), so leaving EN unconnected enables the device. When disabled, TLV76750DGNR draws only 1.5–3 µA and actively pulls the OUT pin to GND via an internal pulldown circuit.

What is the dropout voltage specification for TLV76750DGNR at full load?

At 1 A output current and +25°C, TLV76750DGNR exhibits a typical dropout voltage of 0.9 V and a maximum of 1.5 V (DGN package). This means it maintains 5.0 V regulation with input as low as 6.5 V. Dropout increases slightly at higher temperatures and lower input voltages - see Figure 7-15 in the datasheet for full VIN/IOUT/TJ characterization.

Can TLV76750DGNR be used in automotive applications?

TLV76750DGNR is qualified for industrial temperature range (–40°C to +125°C) and meets JEDEC JESD22 reliability standards, but it is not AEC-Q100 qualified. For non-safety-critical automotive subsystems (e.g., infotainment USB ports), it may be deployed with system-level validation. For ASIL-compliant functions, TI recommends automotive-grade alternatives like TLS850F5BHTSA1.
