Texas Instruments TLV7163030PDPQR

Overview

TLV7163030PDPQR from Texas Instruments is a capacitor-free, dual-channel, 150-mA low-dropout (LDO) voltage regulator with fixed 3.0 V and 3.3 V outputs, 1.5% accuracy over –40°C to 125°C, dropout voltage as low as 0.21 V at 150 mA, and stable operation without input or output capacitors. It powers core logic and I/O rails in space-constrained portable electronics.

For engineers reviewing the TLV7163030PDPQR datasheet, TLV7163030PDPQR pinout, TLV7163030PDPQR application, or TLV7163030PDPQR equivalent, key selection criteria include dual-rail fixed-output capability, inrush current control, no-capacitor stability, thermal shutdown behavior, and 1.2-mm × 1.2-mm X2SON package compatibility with high-density PCB layouts.

Technical Context

The TLV7163030PDPQR integrates two independent PMOS-based LDO regulators sharing a common IN and GND, each with dedicated EN and OUT pins. Its internal control loop enables capacitor-free stability by eliminating phase-margin dependency on external capacitance.

It features active pulldown (120 Ω) on both outputs during shutdown (TLV716P variant), inrush current limiting during enable transitions, and foldback current protection that reduces output current as VOUT collapses - preventing thermal runaway under short-circuit conditions.

Key Specifications

Pinout & Package

FAQ

What output voltages does the TLV7163030PDPQR provide?

The TLV7163030PDPQR provides fixed 3.0 V on OUT1 and 3.3 V on OUT2. These values are factory-trimmed and non-adjustable; no external resistors are required. Output accuracy is ±1.5% over –40°C to 125°C, making TLV7163030PDPQR suitable for powering core logic and interface rails where tight tolerance is essential.

Does TLV7163030PDPQR require input or output capacitors to operate stably?

No-TLV7163030PDPQR is explicitly designed for capacitor-free operation. Its internal compensation ensures stability with or without input (CIN) or output (COUT) capacitors. However, adding a 0.1–1 µF ceramic capacitor on IN and/or 0.1–100 µF on each OUT improves PSRR, load transient response, and noise performance. TLV7163030PDPQR's architecture eliminates capacitor dependency, not capacitor benefit.

How does the enable functionality work on TLV7163030PDPQR?

TLV7163030PDPQR has two independent active-high enable pins: EN1 controls OUT1 (3.0 V) and EN2 controls OUT2 (3.3 V). Driving either EN pin above 0.9 V enables its respective regulator; pulling it below 0.4 V disables the regulator and activates the 120-Ω active pulldown on that output. This allows precise sequencing and fast discharge-critical for power-domain isolation in complex systems using TLV7163030PDPQR.

What protection features are built into TLV7163030PDPQR?

TLV7163030PDPQR includes foldback current limiting, thermal shutdown (trip at ~158°C, reset at ~140°C), undervoltage lockout (~1.3 V), and reverse-voltage protection via the PMOS body diode (with external Schottky recommended for sustained reverse bias). These features ensure robust operation under overload, overtemperature, brownout, and fault conditions-key for reliability in TLV7163030PDPQR-based designs.

Can TLV7163030PDPQR be used in automotive applications?

Yes-TLV7163030PDPQR is qualified for operation from –40°C to 125°C junction temperature and meets AEC-Q200 stress-test requirements for passive components. Its 1.5% accuracy over full temperature range, low dropout, and thermal shutdown make it suitable for infotainment power rails, ADAS camera modules, and body-control sub-systems where space and efficiency are constrained. Always verify PCB layout thermal performance per JEDEC High-K board data.
