HGSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-263-5
LT1764S from HGSEMI, in a TO-263-5. 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 | EN | input | Enable (Input): active-high CMOS compatible control input that must not be left floating; the datasheet gives logic thresholds of 0.8V low (OFF) and 2.4V high (ON). |
| 2 | IN | power_in | Unregulated input, +2.8V to +16V maximum (operating input voltage range is stated as 3V to 16V in the Operating Ratings). |
| 3 | GND | power_in | Ground; the TAB is also connected internally to the IC's ground on this package. |
| 4 | OUT | power_out | Regulator output voltage. |
| 5 | ADJ | input | Feedback voltage input: 1.24V feedback from the external resistor divider that sets the output voltage (output adjustable from 1.24V to 15V). |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
