Texas Instruments TLV70711PDQNR

Overview

TLV70711PDQNR from Texas Instruments is a 200-mA, low-quiescent-current (25 μA), low-noise LDO regulator with 1.1-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 with only 0.1-μF output capacitance-enabling compact power supply design in space-constrained portable electronics.

For engineers reviewing the TLV70711PDQNR datasheet, TLV70711PDQNR pinout, TLV70711PDQNR application, or TLV70711PDQNR equivalent, key selection criteria include dropout voltage at 150 mA (≤220 mV for 1.1-V output), active pulldown resistance (120 Ω), shutdown current (1 μA), thermal shutdown/overcurrent protection, and compatibility with low-bias-voltage GPIO enable control.

Technical Context

The TLV70711PDQNR implements a PMOS pass transistor architecture enabling ultra-low dropout and reverse-body-diode conduction management. Its internal bandgap reference and error amplifier deliver 0.5% output accuracy across –40°C to +125°C junction temperature, while the active-high EN pin (VIH = 0.9 V) supports direct interfacing with low-voltage logic outputs.

Unlike standard TLV707 variants, the TLV70711PDQNR includes an integrated 120-Ω active pulldown circuit that discharges the output during shutdown-critical for preventing floating rails in multi-rail systems. Stability is guaranteed with ≥0.1-μF effective output capacitance, accommodating X5R/X7R ceramics under bias and temperature derating.

FAQ

What is the minimum input voltage required for TLV70711PDQNR to regulate 1.1 V at 150 mA?

The TLV70711PDQNR requires a minimum input voltage of 1.32 V to maintain regulation at 150 mA, based on its maximum dropout voltage of 220 mV at that load. This enables operation from deeply discharged single-cell lithium batteries while sustaining full functionality of connected 1.1-V logic.

Does TLV70711PDQNR require an external pull-up resistor on the EN pin?

No, TLV70711PDQNR does not require an external pull-up on EN. The device features an internal pull-down, and EN is driven actively high (VIH ≥ 0.9 V). Connecting EN directly to a GPIO or to IN (for always-on operation) is sufficient; no external biasing components are needed.

Can TLV70711PDQNR be used with a 0.1-μF output capacitor, and what type is recommended?

Yes, TLV70711PDQNR is explicitly stable with ≥0.1-μF effective output capacitance. X5R or X7R ceramic capacitors in 0402 or 0603 packages are recommended-e.g., a 0.22-μF, 6.3-V X5R part-which maintains ≥0.1 μF under bias and temperature, ensuring stability without oversized components.

How does the 120-Ω pulldown in TLV70711PDQNR improve system reliability?

The 120-Ω pulldown in TLV70711PDQNR actively discharges the 1.1-V output rail during shutdown, preventing floating voltages that could cause leakage, unintended logic states, or latch-up in downstream ICs. This eliminates need for external discharge circuits and improves deterministic power sequencing in multi-rail portable systems.

Is TLV70711PDQNR compatible with lead-free reflow profiles and IPC/JEDEC J-STD-020 moisture sensitivity level?

Yes, TLV70711PDQNR in the DQN (X2SON) package is rated MSL-1 per J-STD-020 and fully compatible with standard lead-free reflow profiles (peak temperature ≤260°C). Its 1.0-mm × 1.0-mm body and thermal pad support reliable solder joint formation in high-volume SMT assembly.
