MSKSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
RT9078N-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 supply input, operating range 2V to 5.5V (absolute maximum -0.3V to 6V), with 1uF or larger input capacitor placed close to VIN and GND. |
| 2 | GND | power_in | Ground pin; input and output capacitor grounds must return to this pin with short, wide traces. |
| 3 | EN | input | Enable control input; pulling EN low enters shutdown mode (VIH 1.0V rising, VIL 0.4V falling, absolute maximum -0.3V to 6V). |
| 4 | SNS | input | Output voltage sense input used for the adjustable output (0.8V reference), with sense input current of 0.5uA max when SNS = VOUT. |
| 5 | VOUT | power_out | Regulated voltage output delivering up to 300mA, stable with 1uF to 22uF ceramic output capacitor placed close to VOUT and GND. |
