AH1117CLTR50

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

AH1117CLTR50 from BL Shanghai Belling, in a SOT-223-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground pin. For the fixed-output AH1117CLTR50 variant this pin is the device ground reference. On the adjustable version this same pin becomes the ADJ feedback input (Vss/Adj).
2 VOUT power_out Regulated 5.0V output pin (Vout typ. 5.0V, min 4.9V, max 5.1V) capable of sourcing up to 1A. Requires a 10uF output capacitor for stability. Electrically connected to the SOT-223 heat-slug tab.
3 VIN power_in Unregulated supply input. Recommended operating input voltage up to 12V (absolute maximum 15V). A 10uF bypass capacitor from VIN to GND is recommended.
4 VOUT (Tab) power_out SOT-223 metal tab, electrically bonded to VOUT and used as the primary heat-dissipation path. Should be soldered to a copper pour tied to VOUT to reduce the ~20 °C/W package thermal resistance.
