Texas Instruments TLV70710DQNR

Overview

TLV70710DQNR from Texas Instruments is a 200-mA, low-quiescent-current (25 µA), low-noise LDO regulator with 0.5% output accuracy and 100-mV dropout at 150 mA (V_OUT = 1.0 V). It operates from 2.0 V to 5.5 V input and delivers stable 1.0 V output for power-sensitive portable electronics such as wearables and wireless handsets.

For engineers reviewing the TLV70710DQNR datasheet, TLV70710DQNR pinout, TLV70710DQNR application, or TLV70710DQNR equivalent, key selection criteria include its ultra-low IQ, 0.1-µF minimum output capacitance stability, 70 dB PSRR at 100 Hz, thermal/overcurrent protection, and 1-mm × 1-mm X2SON package footprint.

Technical Context

The TLV70710DQNR uses a PMOS pass transistor architecture enabling low dropout and reverse-voltage tolerance via an internal body diode. Its enable logic requires only 0.9 V to activate, supporting direct interface with low-voltage GPIOs.

It features integrated thermal shutdown and current limiting (240–450 mA), with shutdown current of 1 µA and active pulldown resistance of 120 Ω (TLV707P variant). The device regulates accurately across –40°C to +125°C junction temperature with no load required.

FAQ

What is the minimum input voltage required for TLV70710DQNR to regulate 1.0 V output at 150 mA?

The TLV70710DQNR requires a minimum input voltage of 1.1 V to maintain regulation at 150 mA, based on its 100-mV dropout specification. At lighter loads (e.g., 30 mA), dropout drops to ~40 mV, allowing operation down to ~1.04 V input. Operation below recommended 2.0 V input is not characterized and may compromise PSRR, noise, or stability.

Can TLV70710DQNR be used without an enable signal, and how should EN be connected?

Yes - TLV70710DQNR can operate without external enable control by connecting the EN pin directly to the IN pin. This configures the device for always-on operation. If dynamic control is needed, drive EN ≥0.9 V to enable and ≤0.4 V to enter 1-µA shutdown mode. Do not leave EN floating, as undefined logic states may cause erratic behavior.

Does TLV70710DQNR support reverse-voltage protection at the OUT pin?

No - TLV70710DQNR contains a PMOS pass transistor with an intrinsic body diode that conducts when V_OUT > V_IN. This allows reverse current flow but provides no current limiting. For applications with potential reverse bias (e.g., hot-swap, backup battery), external reverse-current blocking (e.g., Schottky diode or ideal diode controller) is required to prevent damage or system upset.

What output capacitor types and values are validated for TLV70710DQNR stability?

TLV70710DQNR is stable with ≥0.1 µF effective capacitance at the OUT pin, including X5R/X7R ceramic capacitors rated 0.1 µF or larger. Larger values (e.g., 1 µF) improve transient response. Avoid high-ESR electrolytics or uncharacterized polymer types. Effective capacitance must account for DC bias and temperature derating - a 1-µF 0603 X7R capacitor at 1.0 V bias typically retains >0.8 µF, well above the 0.1 µF threshold.

Is TLV70710DQNR pin-compatible with other variants in the TLV707 family?

Yes - all TLV707x and TLV707Px variants (e.g., TLV70712, TLV70715, TLV70718) share identical DQN (X2SON-4) pinout and footprint. Output voltage is set internally; no external resistors are needed. However, TLV707P versions include active pulldown (120 Ω) on shutdown, while standard TLV707 does not - verify functional compatibility for discharge-critical applications.
