Texas Instruments TLV761C0KVUR

Overview

TLV761C0KVUR from Texas Instruments is a fixed-output, 1A linear voltage regulator in TO-252 (KVU) package with 3.0V output, ±1% accuracy over line/load, 60μA quiescent current, and 18V max input. It serves as a low-noise post-regulator in power rails requiring tight regulation and low standby consumption-e.g., smart meter microcontroller cores.

For engineers reviewing the TLV761C0KVUR datasheet, TLV761C0KVUR pinout, TLV761C0KVUR application, or TLV761C0KVUR equivalent, key selection criteria include dropout voltage at 1A (1.6V max), PSRR (60dB @ 1kHz), thermal shutdown threshold (180°C), stability with 1µF ceramic output capacitors, and compatibility with legacy x1117-based layouts.

Technical Context

The TLV761C0KVUR implements a CMOS pass transistor architecture with internal bandgap reference (0.8V), undervoltage lockout (UVLO rising at 2.4V), foldback current limiting (ICL = 1.1–1.6A), and thermal shutdown (180°C trip, 160°C reset). Its hybrid brick-wall/foldback protection enables robust fault handling without external circuitry.

It delivers high PSRR (>60dB @ 1kHz, >40dB @ 1MHz) to suppress switching noise from upstream DC/DC converters, and features 500µs internal soft-start to limit inrush current-critical for systems using large output capacitance (e.g., 22µF) without oversized input bulk caps.

Key Specifications

Pinout & Package

TLV761C0KVUR uses the 3-pin TO-252 (KVU) package: 6.6mm × 10.11mm footprint with exposed thermal pad soldered to PCB ground plane for enhanced heat dissipation (R_θJA = 67.2°C/W).

FAQ

What is the maximum input voltage rating for TLV761C0KVUR?

The TLV761C0KVUR has an absolute maximum input voltage rating of 20V, with recommended operation up to 18V. Exceeding 20V risks permanent damage. The device operates reliably across its full 2.5V–18V input range, making TLV761C0KVUR suitable for 12V and 15V industrial bus applications with margin for transients.

Does TLV761C0KVUR require external capacitors for stability?

Yes - TLV761C0KVUR requires a minimum 1µF ceramic output capacitor placed adjacent to the OUT and GND pins for stability. An input capacitor is not mandatory but strongly recommended (≥1µF) to counteract source inductance and improve transient response. TLV761C0KVUR remains stable with low-ESR ceramics, eliminating need for tantalum or electrolytic types.

What protection features does TLV761C0KVUR include?

TLV761C0KVUR integrates foldback current limiting (ICL = 1.1–1.6A), thermal shutdown (180°C trip, 160°C reset), undervoltage lockout (2.4V rising, 1.9V falling), and internal output pulldown. These features enable autonomous fault recovery and safe power-down behavior without external components - a key advantage over basic regulators like LM1117 or TLV1117.

Is TLV761C0KVUR pin-compatible with standard x1117 regulators?

Yes - TLV761C0KVUR in the KVU (TO-252) package is pin-to-pin compatible with LM1117 and TLV1117 devices in the same 3-pin TO-252 outline. This allows direct replacement in existing designs to upgrade accuracy, reduce quiescent current, and add protection features without layout changes.

What is the thermal performance of TLV761C0KVUR in its TO-252 package?

In the TO-252 (KVU) package, TLV761C0KVUR has a junction-to-ambient thermal resistance (R_θJA) of 67.2°C/W under JEDEC standard PCB conditions. With proper thermal pad soldering and PCB copper area, it sustains 1A output current at ambient temperatures up to 85°C - verified by its –40°C to +125°C operating junction range and thermal shutdown thresholds.
