LD29300P2MTR from STMicroelectronics, in a TO-263-6. 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 | ADJ | input | Adjust/feedback pin; internal reference is 1.23 V (±1% at 25°C) measured between OUTPUT and GND with ADJ tied to VOUT, and draws a maximum adjust-pin current of 1 µA, used with an external resistor divider to set VO = VREF(1+R1/R2). |
| 2 | OUTPUT | power_out | Regulated output voltage pin, guaranteed output current up to 3 A with load regulation of 0.2% typ (1.0% max) over IO = 10 mA to 3 A. |
| 3 | GND | power_in | Ground reference pin; quiescent (ground) current is 20-50 mA typ/max at IO = 1.5 A and 45-100 mA at IO = 3 A (TJ = -40 to 125°C). |
| 4 | INPUT | power_in | DC input voltage pin; absolute maximum DC input voltage is 30 V (device is automatically forced into shutdown above 14 V), with a minimum operating input voltage of 2.5 V for IO up to 3 A. |
| 5 | INH | input | Logic-controlled shutdown (inhibit) input: logic-low ≤0.8 V puts the device in OFF mode, logic-high ≥2 V is ON mode, drawing 5-10 µA at VINH = 13 V. |
| 6 | GND | power_in | Metal tab, internally connected to the GND pin, provides the main heat-dissipation path (RthJC = 3 °C/W) and must be grounded. |
| 7 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
