LT1764S

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).
