Texas Instruments TLV70719PDQNR

Overview

TLV70719PDQNR from Texas Instruments is a 200-mA, low-noise, low-quiescent-current (25 µA) LDO regulator with 1.9-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 down to 0.1-µF output capacitance - enabling compact, cost-effective power supply design for battery-powered RF subsystems.

For engineers reviewing the TLV70719PDQNR datasheet, TLV70719PDQNR pinout, TLV70719PDQNR application, or TLV70719PDQNR equivalent, key selection criteria include dropout voltage at 150 mA (220–270 mV), active pulldown resistance (120 Ω), shutdown current (1 µA), thermal shutdown protection, and X2SON-4 package compatibility with space-constrained portable layouts.

Technical Context

The TLV70719PDQNR integrates a PMOS pass transistor with internal current limiting and thermal shutdown, supporting safe operation across –40°C to +125°C junction temperature. Its enable logic requires only 0.9 V to activate and 0.4 V to disable, compatible with low-voltage GPIOs.

Unlike standard TLV707 variants, the "P" suffix denotes integrated active pulldown circuitry that discharges the output via a 120-Ω internal resistor during shutdown - critical for preventing floating rail conditions in multi-rail systems and ensuring controlled power sequencing.

FAQ

What is the minimum output capacitance required for stable operation of TLV70719PDQNR?

The TLV70719PDQNR is stable with an effective output capacitance of just 0.1 µF - meaning the actual capacitance under operating bias and temperature must meet or exceed this value. This allows use of compact 0402 X5R/X7R ceramics and reduces total solution size versus traditional LDOs requiring ≥1 µF.

Does TLV70719PDQNR include active pulldown functionality, and how does it operate?

Yes, TLV70719PDQNR includes active pulldown: when the EN pin is driven below 0.4 V, an internal 120-Ω resistor connects OUT to GND, rapidly discharging the output rail. This prevents floating voltages and unintended wake-up in downstream circuits - a feature absent in non-"P" TLV707 variants.

What is the dropout voltage of TLV70719PDQNR at 150 mA load current?

At 150 mA output current, the dropout voltage of TLV70719PDQNR is 220–270 mV (typical to max), depending on junction temperature and input conditions. This enables reliable 1.9-V regulation from as low as 2.12 V input - ideal for single-cell Li-ion or shared intermediate bus architectures.

Can TLV70719PDQNR be used without an enable signal, and how?

Yes - TLV70719PDQNR can operate without external enable control by connecting the EN pin directly to the IN pin. This configures the device for always-on operation, simplifying design where dynamic power gating is unnecessary while retaining all other performance characteristics.

What protection features are integrated into TLV70719PDQNR?

TLV70719PDQNR integrates thermal shutdown and overcurrent protection. When output current exceeds ~240–450 mA (depending on V_OUT), the device enters current-limit mode. If excessive power dissipation raises junction temperature beyond ~150°C, thermal shutdown disables regulation until safe temperature is restored.
