GS2019-33TR5

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

GS2019-33TR5 from Gainsil, 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 from 1.8V to 7.0V with an absolute maximum supply voltage of 8.0V (-0.3V to 8.0V).
2 GND power_in Ground pin; the datasheet recommends separate ground planes for VIN and VOUT, each connected only at this GND pin.
3 EN input Chip enable input; the datasheet specifies a high threshold of at least 1.5V and a low threshold of at most 0.4V, with an absolute maximum of -0.3V to 8.0V.
4 NC unconnected Not connected.
5 VOUT power_out Regulated output, selectable from 1.2V to 5.0V (this part is the 3.3V variant); the datasheet gives a 500mA output current rating and absolute maximum of -0.3V to (VIN+0.3V).
