Texas Instruments TPS7A1006PDSER

Overview

TPS7A1006PDSER from Texas Instruments is a 300-mA, ultra-low-dropout linear regulator (LDO) with dual-supply architecture (VIN + VBIAS), supporting input as low as 0.75 V and output down to 0.5 V. It delivers ±1.5% output accuracy over load, line, and temperature (–40°C to +125°C), features 70 mV max dropout at 300 mA (YKA package), and targets core power for ultra-low-voltage MCUs and analog sensors in space-constrained wearable devices.

For engineers reviewing the TPS7A1006PDSER datasheet, TPS7A1006PDSER pinout, TPS7A1006PDSER application, or TPS7A1006PDSER equivalent, key selection criteria include its dual-rail bias architecture enabling LILO (low-input/low-output) operation, active output discharge (P-version only), sub-1-µA shutdown current, and WSON-6 (DSE) package compatibility with high-density PCB layouts.

Technical Context

The TPS7A1006PDSER implements a dual-supply LDO topology where VIN supplies the pass element while VBIAS powers internal control circuitry-enabling stable regulation even when VIN is only 70 mV above VOUT. Its global UVLO requires both VIN > 675 mV (rising) and VBIAS > 1.54 V (rising) before enabling regulation.

It integrates an active pulldown resistor (120 Ω, P-version only) on the OUT pin during disable or thermal shutdown, ensuring monotonic startup via built-in soft-start and delivering 60 dB PSRR at 1 kHz for noise-sensitive analog rails.

FAQ

What is the output voltage of the TPS7A1006PDSER?

The TPS7A1006PDSER is a fixed-output LDO delivering 0.6 V with ±1.5% accuracy over load, line, and temperature (–40°C to +125°C). This value is laser-trimmed during production and does not require external feedback resistors. The '06' suffix in the part number explicitly denotes the 0.6-V output variant within the TPS7A10 family.

Does the TPS7A1006PDSER require both VIN and VBIAS to operate?

Yes-the TPS7A1006PDSER requires both VIN and VBIAS to be present above their respective UVLO thresholds (VIN > 675 mV, VBIAS > 1.54 V) before regulation begins. This dual-rail architecture enables ultra-low dropout operation but mandates proper power sequencing in system design. If only one rail is available, a single-supply LDO like TPS7A05 should be considered instead.

Is active output discharge supported on the TPS7A1006PDSER?

Yes-the 'P' suffix in TPS7A1006PDSER indicates the active-discharge version, which integrates a 120-Ω pulldown resistor between OUT and GND activated during disable or thermal shutdown. This ensures rapid discharge of output capacitance, preventing floating voltages that could cause downstream latch-up or undefined logic states in connected ICs.

What package type is used for the TPS7A1006PDSER?

The TPS7A1006PDSER uses the 6-pin WSON package (TI designation DSE), measuring 1.50 mm × 1.50 mm with an exposed thermal pad. This RoHS-compliant, lead-free package supports reflow soldering and provides superior thermal performance (R_θJA = 188.8°C/W) compared to the smaller 5-pin DSBGA option-making it ideal for thermally demanding applications.

Can the TPS7A1006PDSER be used with a 0.7-V input supply?

No-the absolute minimum VIN for the TPS7A1006PDSER is 0.75 V per datasheet specifications. At 0.7 V, the device remains in UVLO and will not regulate. For inputs below 0.75 V, TI recommends the TPS7A16xx series or alternative architectures such as charge-pump regulators, as the TPS7A1006PDSER's internal bandgap reference and control circuitry require ≥0.75 V to function.
