Texas Instruments TPS72025QDRVRQ1

Overview

TPS72025QDRVRQ1 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 2.5 V with 110 mV dropout, 48 μV_RMS noise (10 Hz–100 kHz), and 80 dB VIN PSRR (10 Hz–10 kHz), enabling stable core power for camera modules and infotainment SoCs in harsh automotive environments.

For engineers reviewing the TPS72025QDRVRQ1 datasheet, TPS72025QDRVRQ1 pinout, TPS72025QDRVRQ1 application, or TPS72025QDRVRQ1 equivalent, this page provides verified technical context, validated pin functions, confirmed automotive-grade performance specs (AEC-Q100 Grade 1, –40°C to +125°C), and real-world implementation guidance for dual-rail LDO design with floating-IN light-load regulation.

Technical Context

The TPS72025QDRVRQ1 implements a dual-rail NMOS-based LDO architecture where VIN supplies the main power path and VBIAS powers the control circuitry independently-enabling high efficiency when VIN is derived from a step-down DC-DC converter. Its BIAS pin requires ≥2.6 V or (VOUT + 1.4 V), while VIN may be as low as (VOUT + 0.5 V), supporting ultra-low headroom operation.

It features monotonic soft-start with 140 μs startup time, built-in overcurrent and thermal shutdown (160°C trip), undervoltage lockout on BIAS (2.45 V nominal, 150 mV hysteresis), and maintains regulation under light loads (<500 μA) even with VIN floating-sourced entirely from VBIAS. This enables seamless transition between active and low-power states in automotive subsystems.

Key Specifications

Pinout & Package

FAQ

What is the minimum input voltage required for TPS72025QDRVRQ1 to regulate 2.5 V output?

The TPS72025QDRVRQ1 requires a minimum steady-state input voltage of 2.61 V (2.5 V + 110 mV dropout) at 350 mA load. Per datasheet Section 6.3, VIN must be ≥(VOUT + 0.5 V) = 3.0 V for guaranteed performance across temperature and process variation. The device remains functional down to 1.1 V VIN but cannot maintain regulation below dropout headroom.

Can TPS72025QDRVRQ1 operate with the IN pin disconnected?

Yes - the TPS72025QDRVRQ1 supports floating-IN operation under light loads ≤500 μA, sourcing all output current from the BIAS pin while maintaining 2.5 V regulation. This feature is explicitly documented in Sections 3 and 8.1.2 of the SBVS278A datasheet and is enabled by its dual-rail architecture.

What is the recommended capacitor for the BIAS pin of TPS72025QDRVRQ1?

Texas Instruments recommends a minimum 0.1 μF ceramic capacitor from BIAS to GND, placed close to the pin. While the BIAS pin draws minimal current (~38 μA), this capacitor improves high-frequency PSRR and stabilizes the control circuitry against noise coupling, especially when VBIAS is shared with other ICs.

Does TPS72025QDRVRQ1 include thermal protection?

Yes - the TPS72025QDRVRQ1 integrates thermal shutdown with a trip temperature of 160°C (rising) and hysteresis of 20°C (reset at 140°C). When triggered, the device disables the pass element and enters a safe high-impedance state until junction temperature falls below the reset threshold, protecting against sustained overload or poor PCB thermal design.

Is TPS72025QDRVRQ1 compatible with standard 2.2 μF X7R ceramic capacitors?

Yes - the TPS72025QDRVRQ1 is fully characterized and guaranteed stable with ≥2.2 μF X5R or X7R ceramic output capacitors having ESR <250 mΩ. No additional series resistance or special capacitor types are required, simplifying layout and reducing bill-of-materials cost compared to older LDOs needing tantalum or polymer solutions.
