LM29302R

HTC Korea TAEJIN Tech · Linear Voltage Regulators (LDO) · TO-263-5

LM29302R from HTC Korea TAEJIN Tech, 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 Chip enable input with TTL/CMOS-compatible thresholds (logic low off ≤0.8V, logic high on ≥2.4V), may be tied to VIN if ON/OFF control is not needed, operating rating up to 26V.
2 VIN power_in Input supply pin, operating up to 26V continuous (60V max for <100msec at ≤1% duty cycle, -20V reverse), with a 0.1µF capacitor to GND recommended for high-impedance sources.
3 GND power_in Ground pin.
4 OUT power_out Regulated output voltage pin delivering up to 3.0A, requiring a minimum 10µF output capacitor for stability at full load.
5 ADJ input Output adjust pin connected to the R1/R2 feedback divider to set VOUT = 1.240 x [1 + (R1/R2)], with a 1.24V typical reference voltage.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
