Texas Instruments TLV707285DQNT

Overview

TLV707285DQNT from Texas Instruments is a 200-mA, low-quiescent-current (25 µA), low-noise LDO regulator delivering 2.85 V output with ±0.5% DC accuracy, 70 dB PSRR at 100 Hz, and stable operation with only 0.1 µF output capacitance. It serves as a power supply for noise-sensitive RF blocks in portable electronics such as smartphone baseband processors and WLAN transceivers.

For engineers reviewing the TLV707285DQNT datasheet, TLV707285DQNT pinout, TLV707285DQNT application, or TLV707285DQNT equivalent, key selection criteria include dropout voltage at 150 mA (250 mV max), thermal shutdown/overcurrent protection, enable logic thresholds (VIH = 0.9 V, VIL = 0.4 V), and compatibility with space-constrained 1-mm × 1-mm X2SON packaging.

Technical Context

The TLV707285DQNT uses a PMOS pass transistor architecture enabling ultra-low dropout and reverse-voltage blocking via an integrated body diode. Its bandgap reference and error amplifier deliver tight load/line regulation (±10 mV typical) across –40°C to +125°C junction temperature.

It operates with input voltages from 2.0 V to 5.5 V and supports fast transient response-evidenced by <100 µs startup time and minimal output voltage deviation (<50 mV) during 1–150 mA load steps-making it suitable for dynamic power domains in battery-powered SoC subsystems.

FAQ

What is the maximum input voltage rating for TLV707285DQNT?

The absolute maximum input voltage for TLV707285DQNT is 6.0 V. However, the recommended operating range is 2.0 V to 5.5 V. Exceeding 6.0 V may cause permanent damage. For reliable operation in battery-powered systems, VIN should remain ≥ (2.85 V + dropout voltage) - e.g., ≥3.1 V at 150 mA load - to maintain regulation. TLV707285DQNT includes internal protection against overvoltage stress within its specified limits.

Does TLV707285DQNT include reverse-current protection?

TLV707285DQNT incorporates a PMOS pass transistor with an intrinsic body diode that conducts when V_OUT > V_IN. This diode is not current-limited, so reverse current must be externally restricted to ≤5% of rated output current (≤10 mA) if sustained reverse bias is expected. The device does not feature active reverse-current blocking. TLV707285DQNT is not intended for back-driving scenarios without external mitigation.

Can TLV707285DQNT operate without an output capacitor?

No, TLV707285DQNT requires a minimum effective output capacitance of 0.1 µF for stability - this value accounts for voltage and temperature derating of the capacitor. While it does not require a specific ESR, a ceramic capacitor (e.g., X5R/X7R) is strongly recommended. Operating without C_OUT or below 0.1 µF effective capacitance risks oscillation and loss of regulation. TLV707285DQNT's stability margin is validated only with ≥0.1 µF.

What is the thermal performance of TLV707285DQNT in its DQN package?

In the 1-mm × 1-mm DQN (X2SON-4) package, TLV707285DQNT has a junction-to-ambient thermal resistance (R_θJA) of 208.1°C/W under standard JEDEC test conditions. With proper PCB copper pour connected to the thermal pad, actual R_θJA can improve to ~120°C/W. The device enters thermal shutdown at ~150°C junction temperature and auto-recovers upon cooling. TLV707285DQNT's low 25 µA quiescent current minimizes self-heating during light-load operation.

Is TLV707285DQNT pin-compatible with other variants in the TLV707 family?

Yes, all TLV707 and TLV707P variants in the DQN (X2SON-4) package - including TLV70712DQNT, TLV70718DQNT, and TLV70733DQNT - share identical pinout (IN, GND, EN, OUT), footprint, and thermal pad layout. Voltage variants differ only in internal feedback network; no PCB changes are needed when substituting within the same package option. TLV707285DQNT is fully interchangeable at the board level with other DQN-packaged TLV707 family members.
