Texas Instruments TPS7A1006PYKAR

Overview

TPS7A1006PYKAR 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 wearables.

For engineers reviewing the TPS7A1006PYKAR datasheet, TPS7A1006PYKAR pinout, TPS7A1006PYKAR application, or TPS7A1006PYKAR equivalent, key selection criteria include its dual-rail bias architecture enabling LILO (low-input/low-output) operation, active output discharge capability (P-version), sub-1-µA VIN quiescent current, and 0.74 mm × 1.09 mm DSBGA-5 footprint.

Technical Context

The TPS7A1006PYKAR uses a dedicated BIAS rail (1.7–5.5 V) to power internal circuitry while VIN supplies the main output path-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 circuit (120 Ω) on the P-version for monotonic discharge during disable or thermal shutdown, and achieves 60 dB PSRR at 1 kHz via high-loop-gain error amplifier design optimized for ceramic capacitor stability with COUT ≥ 2.2 µF.

FAQ

What is the fixed output voltage of the TPS7A1006PYKAR?

The TPS7A1006PYKAR is a factory-programmed fixed-output LDO delivering 0.6 V ±1.5% over temperature, load, and line conditions. This value is laser-trimmed during production and cannot be adjusted externally-ensuring consistent performance across units without external feedback components.

Does the TPS7A1006PYKAR require both VIN and VBIAS to operate?

Yes-the TPS7A1006PYKAR requires simultaneous presence of valid VIN (>675 mV) and VBIAS (>1.54 V) due to its global UVLO AND logic. If either rail falls below its threshold, regulation halts immediately. This dual-rail dependency ensures robust startup and prevents partial operation in brownout conditions.

Is the active output discharge feature available on the TPS7A1006PYKAR?

Yes-the 'P' suffix in TPS7A1006PYKAR denotes the version with integrated active discharge: a 120-Ω pulldown MOSFET engages automatically when EN is low or thermal shutdown activates, discharging the output capacitor rapidly to prevent floating states during power sequencing.

What is the minimum recommended output capacitor for the TPS7A1006PYKAR?

The TPS7A1006PYKAR requires a minimum 2.2 µF ceramic capacitor from OUT to GND for stability and optimal transient response. Larger values (up to 22 µF) improve PSRR and reduce output ripple but do not affect loop stability-TI validates performance across this full range in the datasheet.

Can the TPS7A1006PYKAR be used with a single supply (VIN only, no VBIAS)?

No-TPS7A1006PYKAR mandates a separate VBIAS supply (1.7–5.5 V) to power its internal control circuitry. Attempting to operate without VBIAS violates absolute maximum ratings and will result in undefined behavior or permanent damage. The BIAS pin is not optional.
