Texas Instruments TLV7162828PDPQR

Overview

TLV7162828PDPQR 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 2.8 V and 2.8 V outputs with ±1.5% accuracy over –40°C to 125°C, supports 1.4 V to 5.5 V input, and features independent enable pins (EN1/EN2) for per-channel power control-ideal for dual-rail power management in compact portable electronics.

For engineers reviewing the TLV7162828PDPQR datasheet, TLV7162828PDPQR pinout, TLV7162828PDPQR application, or TLV7162828PDPQR equivalent, key selection considerations include dual-output stability without external capacitors, inrush current control during startup, low crosstalk between channels, thermal shutdown at 158°C, and active pulldown (120 Ω) on both outputs during disable.

Technical Context

The TLV7162828PDPQR integrates two independent PMOS-based LDO regulators sharing a common IN and GND, each with dedicated EN and OUT pins. Its capacitor-free architecture relies on an advanced internal control loop enabling stable operation with zero input/output capacitance, while supporting up to 100 µF output caps for enhanced transient response.

Each channel provides foldback current limiting (typ. 40 mA short-circuit current), undervoltage lockout (~1.3 V), and independent enable logic (EN high >0.9 V, low <0.4 V). The TLV716P variant-confirmed by the 'P' suffix and RPD = 120 Ω in electrical specs-adds active pulldown circuitry to rapidly discharge both outputs during shutdown.

Key Specifications

Pinout & Package

TLV7162828PDPQR 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 R_θJA = 149.3°C/W and ensure thermal reliability at full load.

FAQ

What does the 'P' suffix in TLV7162828PDPQR indicate?

The 'P' in TLV7162828PDPQR denotes the TLV716P series, which includes active pulldown circuitry (120 Ω) on both OUT1 and OUT2 pins. This feature rapidly discharges the outputs during shutdown, preventing back-powering or floating conditions in multi-rail systems. Standard TLV716 variants lack this pulldown and rely on external resistors or natural discharge paths.

Can TLV7162828PDPQR operate without any input or output capacitors?

Yes, TLV7162828PDPQR is explicitly designed for capacitor-free operation-stable with zero input or output capacitance. This eliminates two ceramic capacitors per channel, reducing BOM count and PCB area. However, adding a 0.1–1 µF input cap and 0.1–100 µF output caps improves PSRR, transient response, and noise performance in noise-sensitive applications.

What is the maximum junction temperature and thermal protection behavior of TLV7162828PDPQR?

TLV7162828PDPQR triggers thermal shutdown at approximately 158°C and recovers when junction temperature falls to ~140°C. Its R_θJA is 149.3°C/W on JEDEC High-K board. For reliable operation, keep junction temperature ≤125°C using adequate copper pour on the thermal pad. Continuous thermal cycling indicates excessive power dissipation or insufficient heatsinking.

How does the enable logic work for independent channel control in TLV7162828PDPQR?

TLV7162828PDPQR has two independent enable pins: EN1 controls OUT1, EN2 controls OUT2. Each is active-high with VIH ≥ 0.9 V and VIL ≤ 0.4 V. When an EN pin is low, its corresponding output shuts down and the 120 Ω pulldown activates. EN pins can be tied to GPIOs, microcontroller outputs, or directly to IN for always-on operation-no external pull-up required.

Is TLV7162828PDPQR suitable for powering RF circuits like Bluetooth or Wi-Fi modules?

Yes, TLV7162828PDPQR is well-suited for RF circuits: it delivers 70 µV_RMS output noise (10 Hz–100 kHz), 80 dB PSRR at 100 Hz, and low crosstalk (<0.066 mV/mA), all critical for maintaining RF signal integrity. Its capacitor-free operation also avoids ceramic capacitor aging effects that degrade RF performance over time in portable devices.
