HGSEMI · Linear Voltage Regulators (LDO) · TO-263-5L
IFX1963S from HGSEMI, in a TO-263-5L. 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 | EN | input | Active-high CMOS/TTL compatible enable input (low ≤0.8V off, high ≥2.4V on); do not float, may be tied to IN for continuous operation. |
| 2 | IN | power_in | Unregulated input supply, +2.8V to +16V maximum. |
| 3 | GND | power_in | Ground; the TAB is also connected internally to the IC's ground. |
| 4 | OUT | power_out | Regulator output voltage, adjustable from 1.24V to 15V. |
| 5 | ADJ | input | Feedback input receiving 1.24V from the external resistor divider, VOUT=1.242×(R1/R2+1). |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
