Texas Instruments TLV70725DQNR

Overview

TLV70725DQNR from Texas Instruments is a 200-mA, low-quiescent-current (25 µA), low-noise LDO regulator with 2.5 V fixed output voltage in a 1-mm × 1-mm X2SON (DQN) package. It delivers 0.5% DC accuracy, 70 dB PSRR at 100 Hz, and stable operation with only 0.1 µF output capacitance - optimized for power-sensitive portable RF systems including wireless handsets and wearable electronics.

For engineers reviewing the TLV70725DQNR datasheet, TLV70725DQNR pinout, TLV70725DQNR application, or TLV70725DQNR equivalent, key selection criteria include dropout voltage (325 mV @ 150 mA), shutdown current (1 µA), EN pin logic thresholds (VIH = 0.9 V, VIL = 0.4 V), thermal shutdown/overcurrent protection, and compatibility with space-constrained PCB layouts requiring minimal external components.

Technical Context

The TLV70725DQNR employs a PMOS pass transistor architecture enabling ultra-low dropout and high PSRR across 100 Hz–1 MHz. Its internal bandgap reference and error amplifier maintain tight regulation under load transients up to 150 mA while consuming only 25 µA quiescent current - critical for battery longevity in always-on sensor nodes.

It integrates active-high enable logic with hysteresis-free thresholding (0.4 V disable / 0.9 V enable), supports zero-load regulation, and remains stable with effective output capacitance ≥0.1 µF - allowing use of small-footprint, bias-voltage-derated ceramic capacitors without compromising loop stability.

FAQ

What is the minimum input voltage required for TLV70725DQNR to regulate 2.5 V at 150 mA?

The TLV70725DQNR requires a minimum input voltage of 2.825 V to maintain regulation at 150 mA, calculated as V_OUT + V_DO = 2.5 V + 325 mV. This allows operation from partially discharged single-cell Li-ion batteries (≥2.8 V) without dropout, supporting extended runtime in portable devices.

Does TLV70725DQNR require an external pull-up resistor on the EN pin?

No, TLV70725DQNR does not require an external pull-up resistor on the EN pin. Its EN input draws only 0.01 µA leakage current and features CMOS-compatible thresholds (VIH = 0.9 V, VIL = 0.4 V), enabling direct connection to low-drive GPIOs or tying to IN for always-on operation - simplifying BOM and layout.

Can TLV70725DQNR operate without any load connected to the OUT pin?

Yes, TLV70725DQNR regulates to its specified 2.5 V ±0.5% accuracy even with zero load current. This capability supports standby modes in systems where downstream circuitry may be fully powered down while the LDO remains active - eliminating need for load-switching circuitry in many portable architectures.

What is the thermal performance of TLV70725DQNR in the DQN package?

TLV70725DQNR in the 1-mm × 1-mm DQN package has a junction-to-ambient thermal resistance (R_θJA) of 208.1°C/W. With its 25 µA quiescent current and typical 325 mV dropout at 150 mA, power dissipation stays below 50 mW - resulting in <11°C temperature rise above ambient under worst-case conditions, enabling reliable operation without heatsinking.

Is TLV70725DQNR compatible with 0402-size ceramic capacitors?

Yes, TLV70725DQNR is explicitly designed to be stable with 0.1 µF effective output capacitance, which is readily achieved using standard 0402 X5R or X7R ceramic capacitors rated at 1 µF - accounting for typical 80–90% bias and temperature derating. This enables ultra-compact layouts in space-constrained wearables and mobile accessories.
