RC1117-3.3

RealChip(正芯半导体) · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89

RC1117-3.3 from RealChip(正芯半导体), in a SOT-89. 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 GND power_in Ground pin on the fixed 3.3V version (labelled Adj(GND), the adjust pin on the ADJ version); the block diagram shows it as GND (FIXED).
2 Vout power_out Regulated output of 3.3V (3.234 to 3.366V) at 0 to 800mA load, with a 1.25 to 1.6A current limit.
3 Vin power_in Input supply pin with an absolute maximum of 18V, requiring Vin-Vout of at least 4.75V for the 3.3V version's stated regulation conditions.
