Texas Instruments TLV7163030PDPQT

Overview

TLV7163030PDPQT 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 3.0 V on OUT1 and 3.0 V on OUT2, supports input voltages from 1.4 V to 5.5 V, achieves ±1.5% output accuracy over –40°C to 125°C, and features independent enable pins (EN1/EN2) for per-channel power control-ideal for dual-rail power sequencing in compact portable electronics.

For engineers reviewing the TLV7163030PDPQT datasheet, TLV7163030PDPQT pinout, TLV7163030PDPQT application, or TLV7163030PDPQT equivalent, key selection criteria include capacitor-free operation, dual independent enables, low dropout (e.g., 210 mV at 150 mA for 3.0 V output), 80 dB PSRR at 100 Hz, and thermal shutdown with hysteresis (158°C trip / 140°C reset).

Technical Context

The TLV7163030PDPQT integrates two independent PMOS-based LDO regulators sharing a common IN and GND, each with dedicated EN and OUT pins. Its internal control loop eliminates need for external input/output capacitors while maintaining stability across full load (0–150 mA per channel) and temperature (–40°C to 125°C).

It implements foldback current limiting (40 mA short-circuit current), inrush current control during startup, and undervoltage lockout (UVLO) at ~1.3 V. The TLV716P variant adds active pulldown (120 Ω) on both outputs during shutdown-confirmed for TLV7163030PDPQT by TI's SBVS217B datasheet Section 6.5 (RPD parameter) and Section 7.3.2.

Key Specifications

Pinout & Package

TLV7163030PDPQT uses the X2SON-6 (DPQ) package: 1.2 mm × 1.2 mm body, 0.5 mm pitch, exposed thermal pad. Thermal pad must be soldered to PCB ground plane for optimal thermal performance (R_θJB = 110.1°C/W).

FAQ

What is the output voltage configuration of TLV7163030PDPQT?

TLV7163030PDPQT provides two fixed 3.0 V outputs: OUT1 = 3.0 V and OUT2 = 3.0 V. This is confirmed by the part number suffix "3030" (denoting 3.0 V / 3.0 V) and TI's SBVS217B datasheet Section 1 (title) and Section 6.5 (VOUT test conditions). No external resistors are required-output voltage is factory-trimmed and stable across temperature and load.

Does TLV7163030PDPQT require input or output capacitors for stability?

No-TLV7163030PDPQT is explicitly designed for capacitor-free operation, as stated in its product title and Section 7.4.1 of the SBVS217B datasheet. It remains stable with C_IN = 0 µF and C_OUT = 0 µF. However, adding a 0.1–1 µF ceramic capacitor on IN and/or 0.1–100 µF on each OUT improves PSRR and transient response, per Section 8.2.2.1.

What is the purpose of the pulldown resistor in TLV7163030PDPQT?

The TLV7163030PDPQT (P-suffix) integrates a 120 Ω active pulldown on both OUT1 and OUT2, activated when EN1 or EN2 falls below 0.4 V. As specified in Section 6.5 (RPD parameter) and Section 7.3.2, this rapidly discharges the output capacitance to prevent floating rails, back-powering, or unintended operation of downstream circuitry during shutdown.

What is the maximum junction temperature and thermal protection behavior of TLV7163030PDPQT?

TLV7163030PDPQT triggers thermal shutdown at approximately 158°C (T_SD) and resets at ~140°C, per Section 6.5 and Section 10.3. This hysteresis prevents oscillation near trip point. The device is rated for continuous operation up to 125°C junction temperature; exceeding this risks reliability degradation, so thermal design must ensure T_J ≤ 125°C under worst-case load and ambient conditions.

How does TLV7163030PDPQT handle inrush current during startup?

TLV7163030PDPQT implements inrush current control that limits output charging to constant current during enable assertion, per Section 7.3.2 and Figure 19–21. This prevents input supply sag or overcurrent faults when powering capacitive loads-especially critical in battery-powered systems where peak current must stay within protection IC limits (e.g., <180 mA).
