Texas Instruments TLV707335ADQNR

Overview

TLV707335ADQNR from Texas Instruments is a 200-mA, low-quiescent-current (25 µA), low-noise LDO regulator with 3.35 V fixed output voltage, 0.5% DC accuracy, and 70 dB PSRR at 100 Hz. It operates from 2.0 V to 5.5 V input and delivers stable regulation down to 0.1 µF output capacitance-enabling compact, cost-effective power supply design for battery-powered RF subsystems.

For engineers reviewing the TLV707335ADQNR datasheet, TLV707335ADQNR pinout, TLV707335ADQNR application, or TLV707335ADQNR equivalent, key selection criteria include dropout voltage at 150 mA (220–270 mV), thermal shutdown/overcurrent protection, active-high enable with 0.9 V logic threshold, and X2SON-4 package compatibility with space-constrained portable PCB layouts.

Technical Context

The TLV707335ADQNR implements a PMOS pass transistor architecture enabling ultra-low dropout and high PSRR across 100 Hz–1 MHz. Its internal bandgap reference and error amplifier deliver 0.5% output accuracy over –40°C to +125°C junction temperature, with load regulation of ≤20 mV from 0 to 150 mA.

Unlike standard LDOs, it achieves stability with only 0.1 µF effective output capacitance due to optimized control loop compensation-reducing BOM cost and board area without sacrificing transient response. The device supports fast start-up (100 µs) and features an active pulldown circuit (120 Ω) in the TLV707P variant, though TLV707335ADQNR is the non-pulldown TLV707 version per TI's nomenclature ('A' suffix denotes improved accuracy/current limit, 'DQNR' = X2SON-4).

FAQ

What is the maximum input voltage rating for TLV707335ADQNR?

The absolute maximum input voltage for TLV707335ADQNR is 6.0 V, but the recommended operating range is 2.0 V to 5.5 V. Exceeding 5.5 V may cause permanent damage or degrade reliability, especially under high ambient temperatures. For reliable operation in Li-ion-powered systems, VIN should remain ≤5.5 V even during charging transients.

Does TLV707335ADQNR include thermal shutdown protection?

Yes, TLV707335ADQNR integrates thermal shutdown protection that disables the output when junction temperature exceeds ~150°C. It automatically recovers once temperature falls below the hysteresis threshold (~135°C). This feature prevents catastrophic failure during sustained overload or poor PCB thermal design-ensuring safe operation in sealed wearable enclosures.

Can TLV707335ADQNR operate with zero load current?

Yes, TLV707335ADQNR regulates to its specified 3.35 V ±0.5% accuracy even with no output load (I_OUT = 0 mA). Its ground current remains at 25 µA typical under no-load conditions, making it ideal for always-on monitoring circuits where standby current must be minimized without sacrificing voltage precision.

What is the minimum output capacitance required for stability with TLV707335ADQNR?

TLV707335ADQNR is stable with an effective output capacitance of 0.1 µF or greater-measured under actual operating bias voltage and temperature. This allows use of small-case X5R/X7R ceramics (e.g., 0201 0.1 µF/6.3 V) without external compensation, significantly reducing solution size versus legacy LDOs requiring ≥1 µF.

Is TLV707335ADQNR pin-compatible with other TLV707 variants?

Yes, all TLV707 and TLV707P variants in the DQN (X2SON-4) package-including TLV707335ADQNR-share identical pinout (IN, GND, OUT, EN), footprint, and thermal pad layout. This enables seamless voltage-option substitution (e.g., TLV707125ADQNR or TLV70728ADQNR) without PCB redesign, provided system-level electrical requirements (e.g., PSRR, noise) are verified per variant.
