IBSP3032ADJST5R00 from Inbisen, in a SOT23-5. 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 | IN | power_in | Regulator supply input, 2.7 V to 20 V. Bypass IN to GND with a 2.2 uF (or larger) low-ESR ceramic capacitor (X5R/X7R, 6.3 V-100 V). |
| 2 | GND | power_in | Device ground and reference return for the internal bandgap and error amplifier. |
| 3 | EN | input | Precision enable input. Drive EN high (EN_HIGH ≥ 1.2 V) to turn the regulator on; pull low (EN_LOW ≤ 1.1 V) to shut down (IGND-SD ≈ 1.2 uA). Tie EN to IN for automatic startup. 100 mV logic hysteresis; ~80 us EN-to-VOUT delay. |
| 4 | ADJ | input | Feedback/adjust input. On the ADJ (adjustable) version, connect to the tap of an external R1/R2 divider from OUT to GND to set VOUT = 1.2 V × (1 + R1/R2). Recommended R2 ≤ 200 kΩ to minimize error from the ~2 nA ADJ bias current. On fixed-output versions, ADJ is tied to the load (OUT sense). |
| 5 | OUT | power_out | Regulated output, adjustable from 1.2 V up to VIN − VDROPOUT, 300 mA max. Bypass to GND with ≥2.2 uF low-ESR ceramic (ESR < 0.3 Ω, ESL < 2 nH). Dropout: 67 mV @ 50 mA, 203 mV @ 150 mA, 450 mV @ 300 mA. Current limit ~480 mA. |
