HEERMICR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3
HE2240A33HMR from HEERMICR, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Device ground / common return. Route back to the ground plane with a wide, short trace, and share a single-point GND with input and output capacitors. |
| 2 | VOUT | power_out | Regulated 3.3V output (±2%), up to 250mA. Requires a 10µF X7R/X5R ceramic output capacitor placed as close as possible to VOUT/GND for stability and transient response. |
| 3 | VIN | power_in | Unregulated supply input, 3.0V to 40V absolute range (VOUT + VDROP recommended minimum). Decouple with a 10µF ceramic input capacitor located close to the pin. |
