Product details
Overview
TPS72010QDRVRQ1 from Texas Instruments is an automotive-grade, ultra-low-input-voltage, RF-optimized low-dropout linear regulator with BIAS pin architecture. It delivers 350 mA output current at 1.0 V output voltage, supports 1.1 V to 4.5 V input range and 1.1 V to 3.6 V bias supply, achieves 110 mV dropout at full load, and maintains 48 μVRMS output noise (10 Hz–100 kHz) for camera module power rails.
For engineers reviewing the TPS72010QDRVRQ1 datasheet, TPS72010QDRVRQ1 pinout, TPS72010QDRVRQ1 application, or TPS72010QDRVRQ1 equivalent, key selection criteria include dual-rail operation (VIN + VBIAS), light-load regulation with floating IN, 38 μA quiescent current, AEC-Q100 Grade 1 qualification (–40°C to +125°C), and stability with 2.2-μF ceramic output capacitor.
Technical Context
The TPS72010QDRVRQ1 implements a dual-rail NMOS LDO architecture where VIN supplies the pass element while VBIAS powers the control circuitry-enabling high PSRR (80 dB at 10 kHz) and low noise even at sub-1.2 V outputs. Its BIAS rail must be ≥(VOUT + 1.4 V) or 2.6 V, whichever is greater, and VIN may operate as low as VOUT + 0.5 V.
This architecture enables unique functionality: when VIN is left floating, the device sustains regulated output up to 500 μA load current sourced entirely from VBIAS-critical for power-gating scenarios in infotainment SoCs. The regulator integrates monotonic soft-start, thermal shutdown (160°C trip), undervoltage lockout on VBIAS (2.45 V nominal), and overcurrent protection with 420–800 mA current limit.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.0 V (factory-programmed via EEPROM); ±2% accuracy over temperature, load, and line conditions. |
| Max Output Current | 350 mA continuous; supports transient loads up to 350 mA with ±15 mV deviation in 1 μs. |
| Input Voltage Range | 1.1 V to 4.5 V on VIN; VBIAS must be ≥ max(2.6 V, VOUT + 1.4 V) and ≤ 5.5 V. |
| Dropout Voltage | 110 mV at 350 mA load (VOUT = 1.0 V); enables high efficiency when VIN is only marginally above output. |
| Quiescent Current | 38 μA typical at 1 mA load; enables ultra-low-power standby modes in automotive systems. |
| Noise Performance | 48 μVRMS (10 Hz–100 kHz); meets stringent RF-sensitive analog supply requirements in camera modules. |
| PSRR | 80 dB at 10 kHz (VIN-referred); 70 dB at 10 kHz (VBIAS-referred); suppresses switching noise from upstream DC-DC converters. |
| Start-up Time | 140 μs to 95% of 1.0 V output with 2.2-μF COUT; ensures fast wake-up in safety-critical subsystems. |
Pinout & Package
TPS72010QDRVRQ1 is housed in a thermally enhanced 6-pin WSON package (DRV) measuring 2.00 mm × 2.00 mm with exposed thermal pad. TI recommends soldering the thermal pad to PCB ground for optimal thermal performance (RθJB = 36.1°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Regulated output | Delivers stable 1.0 V to load; requires 2.2-μF ceramic capacitor to GND for stability and transient response. |
| NC (Pin 2) | No connection | Internally unconnected; must remain unconnected on PCB layout. |
| EN (Pin 3) | Enable control input | Active-high logic input; ≥1.1 V enables regulation, ≤0.4 V disables output and reduces ISHDN to 0.5–2.5 μA. |
| BIAS (Pin 4) | Bias supply rail | Powers internal control circuitry; accepts 2.6–5.5 V; bypass with 0.1-μF capacitor recommended for PSRR optimization. |
| GND (Pin 5) | Ground reference | Analog and power ground; connects to thermal pad; must be low-impedance path to system ground plane. |
| IN (Pin 6) | Main power input | Supplies NMOS pass transistor; accepts 1.1–4.5 V; must be ≤ VBIAS under all conditions; bypass with ≥1-μF capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-rail architecture (VIN + VBIAS) | Enables high-efficiency operation where VIN can be as low as VOUT + 0.5 V while VBIAS powers control logic independently. |
| Floating-IN light-load regulation | Maintains 1.0 V output regulation with ≤500 μA load current sourced solely from VBIAS when VIN is disconnected-ideal for DC-DC power-gating. |
| Ultra-low noise & high PSRR | 48 μVRMS noise and 80 dB VIN PSRR at 10 kHz ensure clean power for RF/analog circuits in camera and infotainment systems. |
| Monotonic soft-start | Limits VIN inrush to 100 mA + ILOAD and restricts VOUT overshoot to ≤3%, preventing system reset during power-up. |
| AEC-Q100 Grade 1 qualification | Rated for –40°C to +125°C ambient operation with H2-class HBM ESD (±2 kV) and C6-class CDM ESD (±500 V) robustness. |
| Stable with small ceramic capacitors | Guaranteed stability with ≥2.2-μF X5R/X7R ceramic output capacitor (ESR < 250 mΩ), reducing BOM cost and board area. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS72012QDRVRQ1 | Fixed 1.2 V output; identical package, pinout, and electrical specs except output voltage. | Used where system requires 1.2 V core rail instead of 1.0 V; no change to PCB layout or support components. | Select when target SoC or ASIC specifies 1.2 V core voltage; shares same qualification, noise, and transient performance. |
| TPS74510PQWDRVRQ1 | Higher 500 mA output current; 25 μA IQ; uses different 6-pin WSON (DQN) package with distinct pin mapping (no NC pin). | Suitable for higher-current 1.0 V rails; not pin-compatible-requires layout revision and revalidation of thermal performance. | Choose for designs needing >350 mA or lower quiescent current; verify thermal derating due to different RθJA (72.4°C/W vs 66.5°C/W). |
Compared with TPS72010QDRVRQ1, TPS72012QDRVRQ1 offers identical performance at 1.2 V and drop-in compatibility, while TPS74510PQWDRVRQ1 provides higher current but requires PCB redesign and has different thermal characteristics.

FAQ
What is the output voltage tolerance of the TPS72010QDRVRQ1 over temperature and load?
The TPS72010QDRVRQ1 maintains ±2% output voltage accuracy over the full AEC-Q100 Grade 1 temperature range (–40°C to +125°C), across load currents from 0 to 350 mA, and with input variations within specification. This is achieved via a precision internal voltage reference and feedback loop, ensuring reliable 1.0 V regulation for sensitive automotive loads.
Can the TPS72010QDRVRQ1 operate with the IN pin disconnected?
Yes-the TPS72010QDRVRQ1 supports regulated output with IN floating under light-load conditions (≤500 μA), sourcing current exclusively from the BIAS pin. This feature enables power-gating of upstream DC-DC converters while maintaining MCU or sensor bias, and is explicitly validated in the datasheet's Figure 7 and Section 8.1.2.
What is the minimum required output capacitance for stability of the TPS72010QDRVRQ1?
The TPS72010QDRVRQ1 requires a minimum 2.2-μF ceramic output capacitor (X5R or X7R dielectric) with ESR < 250 mΩ for guaranteed stability across all operating conditions. Lower values risk oscillation or degraded transient response; TI does not guarantee stability with smaller or higher-ESR capacitors.
How does the BIAS pin function in the TPS72010QDRVRQ1?
The BIAS pin on the TPS72010QDRVRQ1 supplies power to the internal control circuitry-not the pass transistor-allowing independent optimization of control rail voltage. It must be ≥ max(2.6 V, VOUT + 1.4 V) and ≤ 5.5 V. This architecture enables high PSRR and low noise while permitting VIN to operate near VOUT.
Is the TPS72010QDRVRQ1 pin-compatible with other devices in the TPS720-Q1 family?
Yes-TPS72010QDRVRQ1 shares identical 6-pin WSON (DRV) package, pinout, and footprint with all fixed-output variants in the TPS720-Q1 family (e.g., TPS72012QDRVRQ1, TPS72015QDRVRQ1). Only the output voltage differs; no PCB changes are needed when substituting within this family.
