What are the key features of TPS71334DRCTG4?

  • Ultra-low 0.125 V typical dropout voltage enables efficient regulation with minimal headroom from battery or supply inputs up to 6 V
  • Dual independent output channels allow powering two separate voltage rails from a single compact SON-10 footprint
  • Fixed/adjustable output configuration provides design flexibility for both preset voltage applications and trimmed output requirements
  • SON-10 no-lead package minimizes PCB area and improves thermal performance through exposed pad heat dissipation

What is TPS71334DRCTG4 used for?

TPS71334DRCTG4 is well suited for dual-rail power management in portable electronics, wearable devices, and wireless sensor nodes where supply voltage is limited to 6 V and dropout must stay below 0.23 V. Its dual output capability allows simultaneous regulation of a digital core rail and an analog or RF supply rail from a single component, reducing BOM count in space-limited designs. The SON-10 package's compact footprint fits tight PCB layouts in IoT modules and medical wearables.

Frequently Asked Questions

What is the dropout voltage of TPS71334DRCTG4 and why does it matter for battery-powered designs?

The TPS71334DRCTG4 has a typical dropout voltage of 0.125 V and a maximum of 0.23 V, meaning it can regulate its output even when the input supply is only 0.23 V above the target output. For a 3.3 V regulated output powered from a Li-ion cell that discharges down to 3.5 V, this allows operation down to approximately 3.53 V input, extending usable battery life compared to regulators with 0.5 V or higher dropout.

How many output rails does TPS71334DRCTG4 provide, and which dual-rail system architectures benefit from this?

TPS71334DRCTG4 provides 2 independent regulated output channels, making it a good fit for system architectures that need separate analog and digital supply rails, such as a 1.8 V digital core plus a 3.3 V analog front-end in a microcontroller-based sensor. Using a single dual-output LDO instead of 2 discrete regulators reduces component count by at least 6 passives and saves approximately 10 mm² to 15 mm² of PCB area.

What is the maximum input voltage for TPS71334DRCTG4, and which power sources are compatible?

The TPS71334DRCTG4 accepts input voltages up to 6 V absolute maximum, making it compatible with single-cell Li-ion batteries (4.2 V max), USB 5 V power, and 5 V regulated DC rails. It is not suitable for 9 V or 12 V bus applications without a pre-regulator stage. Designers should derate to 5.5 V maximum in production to maintain margin against transient overvoltage spikes on USB or adapter-supplied rails.

How does the SON-10 package of TPS71334DRCTG4 improve thermal performance compared to an SOT-23 regulator?

The SON-10 (S-PDSO-N10) no-lead package used by TPS71334DRCTG4 features an exposed thermal pad on the bottom that conducts heat directly to the PCB copper pour, significantly lowering junction-to-board thermal resistance compared to SOT-23 packages that rely solely on lead frame conduction. This allows the TPS71334DRCTG4 to deliver higher continuous output current across both channels at ambient temperatures up to 85°C without exceeding the device's thermal limits.
