Product details
Overview
TL720M05GQKVURQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-grade LDO regulator delivering 5.0V ±2.0% output at up to 500mA, with 40V max input, 500mV dropout at 300mA, and 17µA quiescent current at light loads. It powers always-on systems such as CAN transceivers and microcontrollers in battery-connected automotive modules.
For engineers reviewing the TL720M05GQKVURQ1 datasheet, TL720M05GQKVURQ1 pinout, TL720M05GQKVURQ1 application, or TL720M05GQKVURQ1 equivalent, key selection criteria include cold-crank transient response (±2% VOUT deviation), UVLO thresholds (2.6–2.82V rising), thermal shutdown (175°C), and compatibility with ≥2.2µF ceramic output capacitors.
Technical Context
The TL720M05GQKVURQ1 employs a novel low-quiescent-current architecture optimized for automotive battery-direct operation, supporting cold-crank (3V/µs VIN slew) and load-dump (40V transient) conditions. Its internal protection includes thermal shutdown with 20°C hysteresis, undervoltage lockout, and overcurrent limiting.
Unlike legacy variants, the new-chip version features enhanced line/load transient response, reduced dropout voltage (390mV max at 500mA), and tighter DC accuracy across –40°C to +150°C junction temperature. It operates stably with 2.2µF–220µF output capacitance and ESR ≤2Ω.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0V ±2.0% across line, load, and temperature - ensures reliable MCU/CAN supply under full automotive operating range. |
| Max Input Voltage | 40V - withstands automotive load-dump transients without external clamping. |
| Max Output Current | 500mA - sufficient for powering dual-core MCUs and CAN FD transceivers simultaneously. |
| Dropout Voltage | 390mV (max) at 500mA - enables regulation down to VIN = 5.39V, critical during cold-crank. |
| Quiescent Current | 17µA (typical) at light loads - minimizes standby power loss in always-on gateways and RKE systems. |
| Line Transient Response | ±2% VOUT deviation at 3V/µs VIN slew - maintains stable logic supply during engine cranking. |
| UVLO Threshold | Rising: 2.6–2.82V; Hysteresis: 230mV - prevents erratic startup during battery recovery after deep discharge. |
Pinout & Package
TL720M05GQKVURQ1 is packaged in a thermally enhanced 3-pin TO-252 (KVU) variant, with exposed thermal pad soldered to PCB for efficient heat dissipation (RθJB = 8.6°C/W). The package measures 6.6mm × 10.11mm and supports high-reliability automotive mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Input power-supply voltage | Accepts 3.0V–40V; requires ≥1µF ceramic capacitor close to pin to suppress EMI and support transient response. |
| GND | Ground / thermal reference | Internally connected to exposed thermal pad; must be soldered to large copper pour for thermal management. |
| OUT | Regulated 5.0V output | Requires ≥2.2µF ceramic capacitor (ESR ≤2Ω) for stability; placement within 3mm of pin critical for load-transient performance. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient (–40°C to +150°C junction), enabling use in instrument clusters and BCMs without derating. |
| Ultra-low quiescent current | 17µA typical at light loads - extends battery life in always-on RKE and telematics modules during vehicle sleep mode. |
| Cold-crank robustness | ±2% VOUT deviation during 3V/µs line transients - sustains communication integrity in CAN networks during engine start. |
| Stable with small ceramic capacitors | Works with 2.2µF–220µF X7R/X5R ceramics (ESR ≤2Ω) - eliminates need for costly tantalum or polymer caps. |
| Integrated protection | Thermal shutdown (175°C), UVLO (2.6–2.82V), and current limiting (540–780mA) - reduces external component count and BOM cost. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7B8750QKVURQ1 | 500mA, 40V, 18µA IQ, ±1.5% accuracy, 300mV dropout at 500mA - tighter accuracy and lower dropout but no reverse-polarity protection. | Preferred for new designs requiring higher DC precision; not drop-in due to different enable polarity and thermal pad layout. | Select when ±1.5% output tolerance and <300mV dropout are mandatory; verify PCB land pattern compatibility. |
| TLV73350PQDBVRQ1 | 300mA, 5.5V max input, 25µA IQ, ±1% accuracy - lower voltage rating and current, but smaller SOT-23 package and better light-load efficiency. | Suitable only for sub-300mA auxiliary rails (e.g., sensor biasing); cannot replace TL720M05GQKVURQ1 in main 5V systems. | Use for secondary low-power domains where 40V input and 500mA are unnecessary; avoid in battery-input primary rails. |
Compared with TPS7B8750QKVURQ1 and TLV73350PQDBVRQ1, TL720M05GQKVURQ1 offers superior transient immunity (3V/µs line slew), broader input range (3–40V), and proven legacy robustness in production BCMs - making it optimal for cost-sensitive, high-reliability main 5V rails.

FAQ
What is the maximum input voltage rating for TL720M05GQKVURQ1?
The TL720M05GQKVURQ1 supports a maximum input voltage of 40V, enabling direct connection to automotive 12V battery systems and tolerance of load-dump transients up to 40V. Absolute maximum rating is 42V, but operation above 40V is not recommended per datasheet specifications.
Does TL720M05GQKVURQ1 require an external capacitor on the IN pin?
Yes, TL720M05GQKVURQ1 requires a minimum 1µF ceramic capacitor between IN and GND, placed as close as possible to the IN pin. This capacitor stabilizes input impedance and improves EMI immunity and line transient response - especially critical during cold-crank events.
What is the dropout voltage of TL720M05GQKVURQ1 at full load?
At 500mA output current and TJ = 25°C, the TL720M05GQKVURQ1 exhibits a maximum dropout voltage of 575mV. Typical dropout is 390mV, meaning the device regulates properly down to VIN = 5.39V - essential for maintaining 5V output during low-battery cranking conditions.
Is TL720M05GQKVURQ1 qualified for automotive applications?
Yes, TL720M05GQKVURQ1 is AEC-Q100 qualified for Grade 1 automotive applications (–40°C to +125°C ambient, –40°C to +150°C junction). It undergoes rigorous stress testing including HTOL, TC, and ESD per AEC standards, and is widely deployed in production instrument clusters and BCMs.
Can TL720M05GQKVURQ1 operate with a 2.2µF output capacitor?
Yes, TL720M05GQKVURQ1 is explicitly characterized and guaranteed stable with a 2.2µF ceramic output capacitor (X7R/X5R, ESR ≤2Ω). This enables compact, low-cost designs without requiring larger or more expensive capacitor types - a key advantage over legacy LDOs needing ≥22µF.
