Product details
Overview
TLV76150KVUR from Texas Instruments is a fixed-output 5.0V, 1A linear voltage regulator in TO-252 (KVU) package, designed for high-current, low-quiescent-power applications requiring ±1% output accuracy, 60μA typical IQ, and stable operation with 1µF ceramic output capacitors. It operates from 2.5V to 18V input and delivers regulated 5.0V output for power rails in motor drives and smart meters.
For engineers reviewing the TLV76150KVUR datasheet, TLV76150KVUR pinout, TLV76150KVUR application, or TLV76150KVUR equivalent, key selection criteria include dropout voltage (1.6V max at 1A), PSRR (60dB @ 1kHz), thermal shutdown (180°C), UVLO (2.4V rising threshold), and compatibility with industry-standard x1117 footprints in TO-252.
Technical Context
The TLV76150KVUR implements a CMOS-based pass transistor architecture with integrated foldback current limiting and undervoltage lockout (UVLO) featuring 130mV hysteresis. Its internal soft-start (500µs typical) reduces inrush current during startup, enabling use with up to 22µF output capacitance without external circuitry.
It delivers high PSRR (>60dB at 1kHz, >40dB at 1MHz) to suppress switching noise from upstream DC/DC converters, and maintains regulation across –40°C to +125°C ambient temperature with ±1.75% total output accuracy over line, load, and temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0V ±1% at 25°C; ±1.75% over –40°C to +125°C, 1mA–1A load |
| Max Output Current | 1A continuous; foldback-limited to 1.6A peak and 250mA short-circuit current |
| Input Voltage Range | 2.5V to 18V; absolute maximum 20V; UVLO disables below 2.2V (rising) |
| Dropout Voltage | 1.6V max at 1A load; enables regulation down to VIN = 6.6V for 5.0V output |
| Quiescent Current | 65–100μA typical at no load; drops to ~1.5μA in shutdown mode |
| PSRR | 60dB at 1kHz, 40dB at 1MHz - attenuates DC/DC ripple without added filtering |
| Thermal Protection | Thermal shutdown triggers at 180°C junction; resets at 160°C with hysteresis |
Pinout & Package
TLV76150KVUR uses the 3-pin TO-252 (KVU) package with exposed thermal pad, measuring 6.6mm × 10.11mm. The package supports high-power dissipation via PCB copper area and plated vias under the thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Input supply connection | Accepts 2.5V–18V; requires ≥1µF input capacitor near pin for transient suppression and PSRR optimization |
| OUT (Pin 2, Tab) | Regulated output node | Delivers fixed 5.0V; tab is electrically connected to OUT and serves as primary thermal path to PCB |
| GND (Pin 3) | Ground reference | Return path for load current and internal bias; must be low-impedance connection to minimize noise and instability |
Key Features
| Feature | Design Value |
|---|---|
| Pin-to-pin compatibility | Direct replacement for LM1117/TLV1117 in TO-252 footprint - no PCB redesign needed |
| Stability with low-ESR caps | Guaranteed stable with ≥1µF ceramic output capacitor - eliminates need for tantalum or electrolytic |
| Internal soft-start | 500µs typical ramp time - limits inrush current and reduces required input capacitance |
| Foldback current limit | Transitions from brick-wall (1.6A) to foldback (250mA at short) - minimizes thermal stress during faults |
| Undervoltage lockout | 2.4V enable threshold with 130mV hysteresis - prevents erratic startup during brownout conditions |
Applications
| Motor Drive Power Supply | Smart Meter MCU Rail |
|---|---|
|
Use Scenario: Powers microcontroller, communication ICs, and sensor interfaces in battery-backed or AC-powered motor control units. IC Role / Device Role / Timing Role: Primary 5.0V LDO supplying logic and analog subsystems; replaces switching regulators where low noise and fast transient response are critical. Use Value: 60μA quiescent current extends battery life in standby; 60dB PSRR prevents switching noise coupling into ADC references and timing circuits. |
Use Scenario: Provides clean 5.0V rail for metrology ASICs, real-time clocks, and RF transceivers in ANSI C12.22-compliant smart meters. IC Role / Device Role / Timing Role: Post-regulator after buck converter; ensures stable voltage during load transients caused by PLC or RF burst transmission. Use Value: ±1% accuracy maintains ADC calibration integrity; thermal shutdown (180°C) supports sealed, convection-cooled enclosures. |
| HVAC Control Panel | Home Theater Audio DAC Supply |
|
Use Scenario: Supplies 5.0V to touch controller, display driver, and environmental sensors in wall-mounted HVAC thermostats operating across –40°C to +85°C ambient. IC Role / Device Role / Timing Role: Main system regulator handling variable loads from backlight dimming, button scanning, and wireless polling. Use Value: –40°C to +125°C junction rating ensures reliability in unventilated enclosures; foldback current limit prevents latch-up during ESD-induced faults on front-panel traces. |
Use Scenario: Powers high-resolution audio DACs and op-amps in premium AV receivers where power-supply noise directly impacts THD+N performance. IC Role / Device Role / Timing Role: Ultra-low-noise post-regulator (60µVRMS) for analog signal chain; decouples digital switching noise from sensitive audio stages. Use Value: 40dB PSRR at 1MHz suppresses high-frequency switching artifacts from adjacent SMPS; 1µF ceramic stability simplifies layout in space-constrained chassis. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV1117-50 | Higher 5mA quiescent current; ±2% output accuracy; no UVLO or foldback current limit | Lacks thermal/UVLO protection and soft-start; less suitable for battery or fault-prone environments | Choose TLV1117-50 only if cost is primary concern and design already includes external protection |
| LM1117DT-5.0 | 10mA IQ; ±2% accuracy; no soft-start; higher 1.2V dropout at 1A; TO-252 pinout identical | Lower PSRR (50dB @ 1kHz); requires larger output cap (10µF min) for stability | Use LM1117DT-5.0 only when legacy qualification or long-term availability outweighs efficiency and noise requirements |
Compared with TLV1117-50 and LM1117DT-5.0, the TLV76150KVUR provides tighter accuracy, lower IQ, integrated protections, and superior PSRR - delivering measurable improvements in standby power, noise immunity, and fault resilience without changing TO-252 layout.

FAQ
What is the maximum input voltage rating for TLV76150KVUR?
The TLV76150KVUR has an absolute maximum input voltage rating of 20V, with recommended operating range from 2.5V to 18V. Exceeding 20V risks permanent damage. Operation above 18V is not guaranteed per specifications and may degrade long-term reliability even if within absolute max limits. Always maintain VIN ≤ 18V in normal operation for full parameter compliance.
Does TLV76150KVUR require an input capacitor?
While the TLV76150KVUR is stable without an input capacitor, Texas Instruments recommends ≥1µF ceramic capacitor between IN and GND to improve PSRR, suppress input ripple, and enhance transient response - especially when source impedance exceeds 0.5Ω or the device is located >2 inches from the power source. This is not for stability but for system-level performance.
Can TLV76150KVUR be used with 22µF output capacitance?
Yes - the TLV76150KVUR supports up to 22µF output capacitance, as verified in Figure 5-20 of the datasheet showing inrush current behavior with 22µF COUT. Its internal soft-start (500µs typical) ensures controlled startup, and stability is maintained across the full 1–220µF recommended COUT range when using low-ESR ceramic capacitors.
What thermal metrics apply to TLV76150KVUR in TO-252 package?
The TLV76150KVUR in KVU (TO-252) package has RθJA = 67.2°C/W (JEDEC standard board), RθJC(bot) = 40.5°C/W, ψJB = 45.4°C/W, and ψJT = 31.6°C/W. For accurate in-system junction temperature estimation, TI recommends using ψJB with PCB surface temperature measured 1mm from the package edge, as it better reflects real-world thermal performance than RθJA.
Is TLV76150KVUR pin-compatible with LM1117 in TO-252?
Yes - TLV76150KVUR uses the same 3-pin TO-252 (KVU) footprint as LM1117DT-5.0 and TLV1117-50, with identical pin 1 (IN), pin 2 (OUT/tab), and pin 3 (GND) assignments. No PCB changes are required for drop-in replacement, though designers should verify that the improved specs (lower IQ, tighter accuracy, UVLO) align with system requirements.
