LDK220U50R

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

LDK220U50R from STMicroelectronics, 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 OUT power_out Output voltage of the LDO, guaranteed to supply up to 200 mA output current with internal current and thermal limiting.
2 GND power_in Common ground; all absolute maximum ratings are referred to GND.
3 IN power_in Input voltage of the LDO, operating range 2.5 V to 13.2 V with a DC absolute maximum of 14 V (-0.3 V to 14 V).
