Texas Instruments TLV707135DQNT

Overview

TLV707135DQNT from Texas Instruments is a 200-mA, low-quiescent-current (25 µA), low-noise LDO regulator with 1.35-V fixed output voltage in a 1-mm × 1-mm DQN (X2SON-4) package. It delivers ±0.5% DC accuracy, 70 dB PSRR at 100 Hz, and stable operation with only 0.1-µF output capacitance-enabling compact, cost-effective power delivery for battery-sensitive RF subsystems in portable electronics.

For engineers reviewing the TLV707135DQNT datasheet, TLV707135DQNT pinout, TLV707135DQNT application, or TLV707135DQNT equivalent, key selection criteria include dropout voltage at 150 mA (220 mV typical), shutdown current (1 µA), thermal shutdown/overcurrent protection, and compatibility with low-voltage GPIO enable signals (VIH = 0.9 V).

Technical Context

The TLV707135DQNT implements a PMOS pass transistor architecture enabling ultra-low dropout and fast load transient response. Its internal bandgap reference and error amplifier maintain regulation across –40°C to +125°C junction temperature while supporting no-load operation and high PSRR up to 1 MHz.

Unlike standard LDOs, it requires no external compensation and remains stable with effective output capacitance as low as 0.1 µF-even under bias and temperature derating-reducing BOM count and PCB area. The EN pin supports direct interfacing with low-voltage logic (0.9 V VIH threshold), and the device enters 1-µA shutdown when EN falls below 0.4 V.

FAQ

What is the maximum input voltage rating for TLV707135DQNT?

The absolute maximum input voltage for TLV707135DQNT is 6.0 V. However, the recommended operating input voltage range is 2.0 V to 5.5 V. Exceeding 6.0 V risks permanent damage per the Absolute Maximum Ratings table in the official datasheet. Operation within the recommended range ensures full specification compliance-including 1.35-V output accuracy, 25-µA quiescent current, and thermal protection functionality-for TLV707135DQNT.

Does TLV707135DQNT require an external pull-up resistor on the EN pin?

No, TLV707135DQNT does not require an external pull-up resistor on the EN pin. The EN pin has internal circuitry that allows direct connection to VIN for always-on operation, or to a low-voltage GPIO (≥0.9 V logic high) for controlled enable/disable. Its VIH(EN) threshold is 0.9 V, making it compatible with 1.8-V I/O domains without level shifting. This design simplifies layout and reduces component count for TLV707135DQNT implementations.

Can TLV707135DQNT operate with zero load current?

Yes, TLV707135DQNT regulates to its specified 1.35-V output accuracy even with no load (IOUT = 0 mA). This capability is explicitly confirmed in the datasheet description and electrical characteristics section. At zero load, ground pin current is 25 µA typical, maintaining regulation integrity and enabling use in standby or sleep-mode subsystems where downstream circuitry may be fully powered down-critical for TLV707135DQNT's role in battery longevity optimization.

What is the thermal resistance (RθJA) of TLV707135DQNT in its DQN package?

The junction-to-ambient thermal resistance (RθJA) for TLV707135DQNT in the DQN (X2SON-4) package is 208.1°C/W, as measured on a standard JEDEC 2S2P test board. This value assumes proper thermal pad soldering to a solid copper plane. For high-power or high-ambient-temperature applications, designers should verify junction temperature using TJ = TA + (RθJA × PD), where PD = (VIN – 1.35 V) × IOUT. This RθJA enables TLV707135DQNT to sustain 200 mA continuously at TA ≤ 65°C.

Is TLV707135DQNT pin-compatible with other TLV707 variants?

Yes, TLV707135DQNT shares identical pinout (OUT-GND-EN-IN), package (DQN, X2SON-4), and footprint with all TLV707 and TLV707P family members-including TLV70712DQNT (1.2 V), TLV70718DQNT (1.8 V), and TLV70733DQNT (3.3 V). This allows voltage-scaling flexibility across designs without PCB revision. However, note that TLV707P variants include an active pulldown resistor (120 Ω), while standard TLV707 (e.g., TLV707135DQNT) does not-so functional equivalence depends on whether pulldown is required in the application.
