LM29302AS

HGSEMI · Linear Voltage Regulators (LDO) · TO-263-5

LM29302AS 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 ENABLE input CMOS/TTL-compatible control input where logic high enables the regulator and logic low (0.8V max) shuts it down, with an input range of -0.3V to VIN and a high threshold of 2.4V min.
2 INPUT power_in Supplies the current to the output power device, with a maximum operating input voltage of 26V.
3 GND power_in Ground pin, and the TAB is also connected internally to the IC's ground.
4 OUTPUT power_out Regulator output voltage, programmable between 1.25V and 25V by the external resistor divider.
5 ADJUST input Adjustable regulator feedback input that connects to the resistor voltage divider placed from OUTPUT to GND to set the output voltage, with a 1.240V typical reference.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
