Texas Instruments TLV707115DQNR

Overview

TLV707115DQNR from Texas Instruments is a 200-mA, low-quiescent-current (25 µA), low-noise LDO regulator with 1.15 V fixed output voltage in a 1-mm × 1-mm X2SON (DQN) 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 portable electronics.

For engineers reviewing the TLV707115DQNR datasheet, TLV707115DQNR pinout, TLV707115DQNR application, or TLV707115DQNR equivalent, key selection criteria include dropout voltage at 150 mA (220–270 mV for 1.15 V output), thermal shutdown/overcurrent protection, active-high enable logic (VIH = 0.9 V), and compatibility with low-voltage GPIOs in wearables and IoT edge nodes.

Technical Context

The TLV707115DQNR implements a PMOS pass transistor architecture with bandgap reference and internal current-limit/thermal shutdown circuitry. Its low 25 µA quiescent current and ability to regulate with no load support ultra-low-power standby modes in portable systems.

It achieves high PSRR (70 dB @ 100 Hz, 50 dB @ 1 MHz) and low 45 µV_RMS output noise (100 Hz–100 kHz) through optimized internal compensation and minimal output capacitance requirements - eliminating need for large bulk capacitors while maintaining transient stability under dynamic load steps.

FAQ

What is the maximum input voltage rating for TLV707115DQNR?

The absolute maximum input voltage for TLV707115DQNR is 6.0 V, but the recommended operating range is 2.0 V to 5.5 V. Exceeding 5.5 V may trigger internal protection circuits or reduce reliability; operation above 6.0 V risks permanent damage. Always maintain VIN ≤ 5.5 V in normal use, especially when paired with Li-ion batteries that can reach 4.2 V fully charged.

Does TLV707115DQNR require an external pull-up resistor on the EN pin?

No, TLV707115DQNR does not require an external pull-up resistor on the EN pin. Its enable threshold is VIH = 0.9 V (min), and internal logic ensures reliable turn-on with direct connection to a 1.2-V or 1.8-V GPIO. If the host system lacks a dedicated enable signal, EN may be tied directly to IN - resulting in always-on operation without additional components.

Can TLV707115DQNR operate with zero load current?

Yes, TLV707115DQNR regulates to its specified ±0.5% accuracy even with no output load (I_OUT = 0 mA). This capability supports deep-sleep modes in microcontrollers and sensors where downstream circuitry draws negligible current - maintaining rail integrity without requiring dummy loads or post-regulation shunt elements.

What is the thermal performance of TLV707115DQNR in the DQN package?

TLV707115DQNR in the 1-mm × 1-mm DQN package has R_θJA = 208.1°C/W (junction-to-ambient) and R_θJB = 159.4°C/W (junction-to-board). With proper PCB thermal pad connection (≥4 mm² copper pour), it sustains 200 mA continuous output at ambient temperatures up to +85°C. Derating is required above 100 mA in sealed enclosures without airflow.

Is TLV707115DQNR pin-compatible with other TLV707 variants?

Yes, all TLV707-series devices in the DQN (X2SON-4) package - including TLV707115DQNR - share identical pinout (OUT-GND-EN-IN), footprint, and thermal pad layout. Voltage variants (e.g., TLV70712DQNR, TLV70718DQNR) are drop-in replacements for layout reuse, provided input/output voltage margins and load requirements remain compatible.
