RT9080N-08GJ5-MS

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

RT9080N-08GJ5-MS from MSKSEMI, 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 VIN power_in Power input port; datasheet recommends a 1uF or larger input capacitor placed close to VIN and GND, with operating input range 1.2V to 6V.
2 GND power_in Ground.
3 EN input Enable control; pulling EN low enters shutdown mode (VIH 1.7V rising, VIL 0.6V falling, absolute max -0.3V to 6V).
4 SNS input Output voltage sense input; connect to VOUT for fixed output or to a resistor divider from VOUT for adjustable output (VSNS = 0.8V for RT9080N-08).
5 VOUT power_out Regulated voltage output port delivering up to 600mA, using a 1uF to 22uF output capacitor placed close to VOUT and GND.
