Product details

What this buck regulator does on your rail

The TPS62005DGSR is a fixed 1.8 V output step-down (buck) converter from Texas Instruments, rated for 600 mA continuous output current. It integrates both high-side and low-side switches (synchronous rectifier), which means no external Schottky diode is needed — that saves board space and improves efficiency at light loads. The 10-VSSOP package (3.00 mm × 3.00 mm body) fits tight layouts.

We source per RFQ — confirm your BOM quantity and target lead time, and we'll quote against current market pricing. No stock-holding claim; availability confirmed at quote time.

Design-in checklist — what to watch

Because the output is fixed at 1.8 V, you don't need an external feedback divider — just connect the output pin to the load and add the recommended input/output capacitors. Low-ESR ceramic types (X5R or X7R) are fully compatible. The synchronous rectifier improves efficiency at light loads.

Frequently asked questions

What are the direct alternatives or equivalents to TPS62005DGSR?

Within the same TPS6200x family, there are fixed-output voltage variants (e.g., 1.5 V, 1.8 V, 3.3 V) in the same 10-VSSOP package — check the TPS62000 series datasheet for the exact order code. For higher current or automotive temperature range, the LM53625LQURNLRQ1 (2.5 A, 2.1 MHz, AEC-Q100) is a functional alternative but not pin-compatible (wettable flank QFN package).

Does TPS62005DGSR require any external components?

Yes — it needs an input capacitor (10 µF ceramic recommended), an output capacitor (10 µF ceramic), and an inductor (4.7 µH to 10 µH). Because the output is fixed at 1.8 V, no external feedback resistor divider is required.
