HEERMICR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3
HE2240A36HMR 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 reference. Should be tied to a low-impedance ground plane; input and output capacitor grounds should return here with wide, short traces. |
| 2 | VOUT | power_out | Regulated 3.6V output (Vset0.98 to Vset1.02, IOUT up to 250mA). Requires a 10µF X7R/X5R ceramic capacitor to GND placed close to the pin for stability. |
| 3 | VIN | power_in | Unregulated supply input, 3.0V to 40V absolute max. Bypass with a 10µF ceramic capacitor to GND placed close to the pin. |
