**onsemi** · Linear Voltage Regulators (LDO) · TSOP-5

NCV8164CSNADJT1G from onsemi, in a TSOP-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 | Input voltage supply pin, operating range 1.6 V to 5.0 V, bypassed with at least a 1 µF ceramic capacitor to GND. |
| 2 | GND | power_in | Common ground connection. |
| 3 | EN | input | Chip enable: VEN < 0.2 V disables the regulator and VEN > 0.7 V enables the LDO. |
| 4 | ADJ | input | Adjustable output feedback pin (adjustable version only), with a 1.2 V reference voltage. |
| 5 | OUT | power_out | Regulated output voltage, to be bypassed with a small 1 µF ceramic capacitor. |
