ZD1117ISTR33

Zetta · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

ZD1117ISTR33 from Zetta, in a SOT-89-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Vss/ADJ power_in Ground pin for fixed-output versions, and the adjust pin for the ZD1117-ADJ, whose adjust pin current is 55-120 uA (typ-max) with a 0.2-10 uA change over load.
2 Vout power_out Regulated output voltage; maximum output current is 1A, with 1.3 V dropout at 1A load.
3 Vin power_in Supply voltage input; absolute maximum input is 18V and recommended input range is up to 16V (20V for ZD1117-12V).
