LDK320AM50R

STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

LDK320AM50R from STMicroelectronics, in a SOT-23-5. 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 IN power_in Input voltage supply with operating range 2.5 V to 18 V and typical dropout voltage of 100 mV at 100 mA output current.
2 GND power_in Common ground reference.
3 EN input Enable pin logic input with logic low at ≤0.4 V for shutdown mode and logic high at ≥1.2 V for active mode.
4 ADJ/NC unconnected Not connected on fixed output version; adjustable pin on adjustable variants only.
5 OUT power_out Fixed 5 V output voltage with ±0.5% tolerance at 25°C and ±1.5% across -40 to 125°C, output current capability up to 200 mA.
