Detailed Description

Single-channel, positive adjustable LDO regulator. 1 A output current. Wide adjustable output range 0.9 V to 5 V. Max input voltage 6.5 V. Low dropout 350 mV at 1 A. Low quiescent current 4 mA. Control features include Enable, Power Good, and Soft Start. Robust protections: Over-Current, Over-Temperature, and UVLO. Small 20-VQFN (5 x 5 mm) with exposed thermal pad for efficient heat dissipation. Industrial-grade -40°C to +125°C operation. RoHS3 compliant. Ideal for space-constrained, low-noise power rails that need tight regulation and good headroom.

Key Advantages

Saves headroom with low dropout, supports tighter input-to-output margins

Adjustable output simplifies design across many rails (logic, analog, RF)

Power-Good and Soft-Start improve system sequencing and limit inrush current

Strong protection and UVLO increase system reliability

Small QFN footprint with exposed pad improves thermal performance and reduces board space

Low quiescent current helps efficiency at light load

TI quality and long market presence, supported by Y-IC’s trusted distribution

Packaging

Shipment format: Tape & Reel (TR) for automated assembly

Package type: 20-VQFN (5 x 5 mm), exposed thermal pad

Material: Molded epoxy encapsulation, copper leadframe with plated leads

Size: 5 mm x 5 mm body; low-profile QFN height

Pin count and pitch: 20 leads; fine-pitch QFN (see datasheet for exact pitch)

Pin configuration (typical functional pins): VIN, VOUT, EN, PG, SS, FB, GND, exposed thermal pad (EP); plus other control/sense pins per datasheet

Thermal characteristics: Exposed pad must be soldered to a ground/thermal plane for low thermal resistance and improved heat spreading

Electrical properties summary: 1 A output, 0.35 V max dropout at 1 A, 4 mA Iq, 0.9–5 V adjustable output, up to 6.5 V input, integrated OCP/OTP/UVLO

Lifecycle

Current status: Active within TI’s LDO portfolio (not indicated as near end-of-life per available data)

Close alternatives and potential equivalents (verify pinout and ratings before use):

- TPS7A7001 (TI, adjustable low-dropout LDO, ~1 A class; features differ)

- TPS7A8001 (TI, 1 A low-noise LDO; different input range and noise specs)

- TPS73701 (TI, adjustable LDO; package and electricals may differ)

- TPS7A7200/TPS7A7300 families (higher current or different specs; may fit if you need more headroom or features)

Note: Specs, pinouts, thermal, and noise performance vary. Always cross-check with datasheets and your PCB footprint. If you need exact drop-in replacements or detailed cross-references, contact our sales team via the Y-IC website for personalized support.
