Texas Instruments TLV76725DGNR

Overview

TLV76725DGNR from Texas Instruments is a 1-A, 16-V input precision linear voltage regulator in an 8-pin HVSSOP package, delivering fixed 2.5 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 and consumer systems.

For engineers reviewing the TLV76725DGNR datasheet, TLV76725DGNR pinout, TLV76725DGNR application, or TLV76725DGNR 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 22-µF output capacitance for reduced inrush current.

Technical Context

The TLV76725DGNR implements a CMOS pass transistor architecture with internal 0.8-V reference, foldback current limiting, and undervoltage lockout (UVLO) with 2.2–2.4 V rising threshold and 130-mV hysteresis. It features active-high enable with internal pullup and output pulldown during disable.

Its functional block includes integrated thermal shutdown (180°C trip, 160°C reset), soft-start (500 µs typical), and high-bandwidth error amplifier enabling stable regulation across –40°C to +125°C ambient while supporting both local and remote sensing via SNS pin in fixed-output configuration.

FAQ

What is the maximum input voltage rating for TLV76725DGNR?

The absolute maximum input voltage for TLV76725DGNR is 18 V, but the recommended operating range is 2.5 V to 16 V. Operation above 16 V risks exceeding safe operating area limits and may trigger UVLO or thermal shutdown. The device's 16-V upper limit ensures compatibility with 12-V industrial rails and 15-V adapter inputs while maintaining margin for transients.

Does TLV76725DGNR require an external feed-forward capacitor (CFF)?

No, TLV76725DGNR does not require an external feed-forward capacitor because it is a fixed-output variant - CFF is specified only for adjustable versions to stabilize the feedback loop when feedback divider current falls below 5 µA. The fixed 2.5-V version uses internal resistor network and SNS pin, eliminating need for CFF.

Can TLV76725DGNR operate with a 22-µF output capacitor?

Yes, TLV76725DGNR is stable with output capacitances from 1 µF to 220 µF, including 22 µF ceramic. Application data confirms reduced inrush current with 22-µF C_OUT, making it suitable for systems needing bulk capacitance for hold-up time or transient response - without compromising stability or requiring series ESR.

What is the thermal resistance (R_θJA) of TLV76725DGNR in its HVSSOP package?

The junction-to-ambient thermal resistance (R_θJA) for TLV76725DGNR in the 8-pin HVSSOP (DGN) package is 60.1°C/W under standard JEDEC 2-layer board conditions. This value assumes proper thermal pad soldering to a solid ground plane; omitting thermal pad connection degrades R_θJA by >25°C/W.

How does the enable (EN) pin behave when left floating on TLV76725DGNR?

When the EN pin is left floating, TLV76725DGNR enables automatically due to its internal ~400-nA pullup current. This allows simple "always-on" operation without external biasing. To disable, drive EN ≤ 0.4 V; to ensure robust enable, apply ≥1.2 V. Floating EN is functionally equivalent to tying EN to VIN in most designs.
