Gainsil · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SC-70-5
GS2019-30CR from Gainsil, in a SC-70-5. 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 | Regulator input; supply voltage can range from 2.5V to 5.5V, and it should be bypassed with a 1uF capacitor to GND. |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | EN | input | Shutdown input: a logic low reduces the supply current to 10nA, and it should be connected to IN for normal operation. |
| 4 | BP/FB | passive | On the fixed-voltage version (GS2019-30, 3.0V) this is the reference-noise bypass pin, to be bypassed with a low-leakage 0.01uF ceramic capacitor for reduced output noise; on the adjustable version it is the FB pin that sets the output voltage. |
| 5 | OUT | power_out | Regulator output. |
