Texas Instruments TLV716120275PDPQT

Overview

TLV716120275PDPQT from Texas Instruments is a capacitor-free, dual-channel, 150-mA low-dropout (LDO) voltage regulator in a 1.2-mm × 1.2-mm X2SON-6 (DPQ) package. It delivers fixed outputs of 1.2 V and 2.75 V with ±1.5% accuracy over –40°C to 125°C, supports input voltage from 1.4 V to 5.5 V, and features independent enable pins (EN1/EN2) for power sequencing in portable battery-powered systems.

For engineers reviewing the TLV716120275PDPQT datasheet, TLV716120275PDPQT pinout, TLV716120275PDPQT application, or TLV716120275PDPQT equivalent, key selection considerations include dual-rail fixed-output stability without external capacitors, inrush current control during startup, low crosstalk between channels, foldback current limiting, and thermal shutdown at 158°C.

Technical Context

The TLV716120275PDPQT integrates two independent PMOS-based LDO regulators with separate enable inputs and shared ground. Each channel provides regulated output with no required input or output capacitance, enabled by an advanced internal control loop that maintains stability across load and line transients.

It implements undervoltage lockout (UVLO) at ~1.3 V, active pulldown (120 Ω) on both outputs during shutdown (TLV716P variant), and foldback current limiting that reduces output current as VOUT collapses-limiting power dissipation and enabling safe fault recovery without external circuitry.

Key Specifications

Pinout & Package

TLV716120275PDPQT uses the X2SON-6 (DPQ) package: 1.2 mm × 1.2 mm body, 0.5 mm pitch, exposed thermal pad. The pad must be soldered to a PCB ground plane to achieve RθJB = 110.1°C/W and ensure reliable 125°C junction operation at full load.

FAQ

What is the function of the thermal pad on the TLV716120275PDPQT package?

The exposed thermal pad on the TLV716120275PDPQT must be soldered to a PCB ground plane to achieve specified thermal performance. When properly connected, it lowers junction-to-board thermal resistance to 110.1°C/W, enabling continuous 150-mA operation at 125°C ambient. Omitting this connection risks thermal shutdown at loads above ~80 mA.

Does TLV716120275PDPQT require external capacitors for stability?

No-TLV716120275PDPQT is explicitly designed for capacitor-free operation. Its internal control loop ensures stability with zero input or output capacitance. However, adding a 0.1–1 µF ceramic capacitor on IN and 0.1–100 µF on each OUT improves PSRR, transient response, and noise rejection-especially in noisy environments.

How does the pulldown feature work on TLV716120275PDPQT during shutdown?

When EN1 or EN2 falls below 0.4 V, TLV716120275PDPQT activates an internal 120-Ω resistor between the corresponding OUT pin and GND. This actively discharges the output node-preventing floating voltages that could cause unintended logic states or latch-up in downstream ICs. The pulldown is absent in non-P variants.

Can TLV716120275PDPQT regulate from a 2.85-V input to 2.75-V output reliably?

Yes-TLV716120275PDPQT achieves a typical dropout voltage of 0.23 V at 150 mA for VOUT = 2.75 V, meaning it regulates stably down to VIN ≈ 2.98 V. At lighter loads (e.g., 10 mA), dropout drops to ~0.12 V, enabling regulation from as low as 2.87 V-well within specification for single-cell Li-ion discharge profiles.

What is the maximum junction temperature and thermal shutdown behavior of TLV716120275PDPQT?

TLV716120275PDPQT triggers thermal shutdown at 158°C and resets at 140°C. This hysteresis prevents oscillation during overload. Under sustained fault conditions, it cycles between shutdown and regulation-limiting average power dissipation. For reliable continuous operation, keep TJ ≤ 125°C using proper PCB copper area and thermal pad connection.
