AH1117CLTRAD

BL Shanghai Belling · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-3

AH1117CLTRAD from BL Shanghai Belling, in a SOT-223-3. 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 on fixed-voltage versions and adjust pin on the AH1117-ADJ version, where a 1.25V reference is set by two external resistors R1/R2 and an optional bypass capacitor CADJ to ground improves ripple rejection.
2 Vout power_out Regulated output voltage, up to 1A maximum output current, with a 10uF tantalum output capacitor recommended for stability.
3 Vin power_in Supply voltage input, 15V absolute maximum with a recommended input range of max 12V, bypassed with a 10uF tantalum capacitor.
