Product details
Overview
TPS7A6050QKTTRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-grade 5-V fixed-output low-dropout linear regulator with programmable power-on-reset delay, 25 µA quiescent current at light loads, 300 mA output current capability, and 7–40 V input voltage range. It serves as a primary power supply for microcontrollers and infotainment subsystems in harsh automotive environments.
For engineers reviewing the TPS7A6050QKTTRQ1 datasheet, TPS7A6050QKTTRQ1 pinout, TPS7A6050QKTTRQ1 application, or TPS7A6050QKTTRQ1 equivalent, this page delivers verified technical context, validated pin functions, confirmed automotive operating conditions (–40°C to 125°C ambient), exact reset delay programmability via RDELAY capacitor, and real-world fault protection behavior under cold-crank and load-dump transients.
Technical Context
The TPS7A6050QKTTRQ1 implements a monolithic LDO architecture with integrated charge pump for high-voltage operation, undervoltage lockout (VIN-UVLO = 3.16 V), and thermal shutdown (TSD = 165°C with 10°C hysteresis). Its internal power-on-reset circuit asserts nRST after VOUT exceeds 93% of 5 V (4.65 V typical) and holds reset until programmed delay expires.
Unlike the enable-equipped TPS7A6150-Q1, the TPS7A6050QKTTRQ1 uses pin 4 exclusively as RDELAY - an open-drain timer node charged by 1 µA (typical) current to set tPOR from 300 µs (100 pF) to 300 ms (100 nF). It lacks ENABLE functionality and relies on VIN biasing for activation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5 V ±2% over 10–300 mA load and –40°C to 125°C ambient - ensures stable MCU core supply without external feedback. |
| Input Voltage Range | 7 V to 40 V with 45-V transient tolerance - supports 12-V/24-V automotive systems through load dump and cold-crank events. |
| Quiescent Current | 25 µA typical at light loads - enables always-on modules (e.g., CAN wake-up receivers) to meet <100 µA system standby budgets. |
| Dropout Voltage | 300 mV at 150 mA - allows regulation down to VIN = 5.3 V, critical for battery brownout survival during engine cranking. |
| Reset Threshold | VTH(POR) = 4.65 V (93% of 5 V); UVTHRES = 4.65 V - provides precise, temperature-stable POR and undervoltage detection without external comparators. |
| Thermal Protection | 165°C trip with 10°C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking in enclosed enclosures. |
| ESD Rating | ±4000 V HBM (KVU/TO-252), ±4000 V HBM (KTT/TO-263) - meets AEC-Q100 requirements for assembly and field handling robustness. |
Pinout & Package
TPS7A6050QKTTRQ1 is packaged in a 5-pin TO-263 (KTT/D2PAK) with exposed thermal pad, measuring 10.16 mm × 9.15 mm. The package enables >24°C/W junction-to-ambient thermal resistance when properly soldered to ≥1 in² copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Unregulated input supply | Accepts 7–40 V DC; requires local 1-µF ceramic bypass to GND to suppress transients up to 45 V/50 ns. |
| nRST (Pin 2) | Open-drain reset output | Pulled low during startup or VOUT undervoltage; requires external pullup to VOUT (5 V) for logic-level compatibility. |
| GND (Pin 3) | Signal and power ground reference | Must be connected to low-impedance ground plane; shares thermal pad connection for heat dissipation. |
| RDELAY (Pin 4) | Reset delay timing node | Charged by 1 µA internal current source; connects to CDLY capacitor (100 pF–100 nF) to GND to set tPOR. |
| VOUT (Pin 5) | Regulated 5-V output | Delivers up to 300 mA; requires ≥10 µF low-ESR ceramic output capacitor for stability and PSRR performance. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Power-On Reset Delay | tPOR adjustable from 300 µs to 300 ms using external CDLY capacitor - eliminates need for discrete RC timers in safety-critical boot sequencing. |
| Low-Voltage Tracking Mode | Enables dropout-free operation below 7 V by letting VOUT track VIN minus IOUT×RSW (2 Ω) - reduces input capacitance by up to 50% in cold-crank designs. |
| Integrated Fault Protection | Combines short-circuit current limiting (350–1000 mA), thermal shutdown, and UVLO - removes requirement for external foldback or thermal sensors. |
| Ultra-Low Quiescent Current | 25 µA typical at light loads with automatic charge-pump disable above ~8 V - extends battery life in always-on vehicle modules. |
| AEC-Q100 Grade 1 Qualification | Validated for –40°C to +125°C ambient operation and 150°C junction temperature - certified for front-end electronics including head units and instrument clusters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A6050QKTTQ1 | Same die, identical electrical specs, but in TO-263 (KTT) package without tape-and-reel - no functional difference, only packaging format. | Not suitable for automated SMT placement; used for prototyping or low-volume manual assembly. | Select TPS7A6050QKTTRQ1 for production reels; choose QKTTQ1 only for evaluation or hand-soldered boards. |
| TPS7B6750QPWPRQ1 | 5-V LDO with enable, 350-mA output, 28-µA IQ, but no RDELAY pin or programmable reset - fixed 200-ms POR delay. | Lacks reset delay customization; requires external POR IC if precise timing alignment is needed with downstream logic. | Choose TPS7B6750QPWPRQ1 only when enable control is mandatory and reset timing flexibility is not required. |
Compared with TPS7A6050QKTTRQ1, TPS7A6050QKTTQ1 offers identical performance in non-reel form, while TPS7B6750QPWPRQ1 trades RDELAY programmability for ENABLE functionality - making the former ideal for volume manufacturing and the latter better suited for enable-driven power sequencing.

FAQ
What is the maximum input voltage transient tolerance for TPS7A6050QKTTRQ1?
The TPS7A6050QKTTRQ1 supports input transients up to 45 V for durations less than 480 ms, as specified in its Absolute Maximum Ratings table. This enables robust operation during ISO 7637-2 Load Dump pulses in 12-V automotive systems without requiring external TVS clamping, provided layout minimizes inductance on the VIN path.
Does TPS7A6050QKTTRQ1 include an enable pin?
No, TPS7A6050QKTTRQ1 does not have an ENABLE pin. It belongs to the TPS7A60-Q1 family, which uses RDELAY (pin 4) for reset delay programming. The ENABLE function is exclusive to the TPS7A61-Q1 series (e.g., TPS7A6150-Q1), where pin 4 serves as a high-voltage-tolerant enable input instead of RDELAY.
How is the power-on-reset delay configured on TPS7A6050QKTTRQ1?
The power-on-reset delay on TPS7A6050QKTTRQ1 is configured by connecting an external capacitor (CDLY) between pin 4 (RDELAY) and GND. With CDLY = 100 nF, tPOR ≈ 300 ms; with CDLY = 100 pF, tPOR ≈ 300 µs. If CDLY is omitted, the device defaults to a 250 µs internal delay - confirmed in Section 7.6 of the SLVSA62J datasheet.
What output capacitor is required for stable operation of TPS7A6050QKTTRQ1?
TPS7A6050QKTTRQ1 requires a minimum 10 µF ceramic output capacitor with ESR ≤ 10 mΩ for guaranteed stability across temperature and load. The device is optimized for low-ESR ceramics (X5R/X7R) and does not require series resistance; adding ESR intentionally may degrade PSRR and transient response.
Is TPS7A6050QKTTRQ1 qualified for automotive use?
Yes, TPS7A6050QKTTRQ1 is AEC-Q100 Grade 1 qualified, rated for operation from –40°C to +125°C ambient temperature and –40°C to +150°C junction temperature. It includes automotive-specific features including 45-V transient tolerance, integrated thermal shutdown, and fault protection - all validated per AEC-Q100 test requirements.
