# MIC29152S

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

MIC29152S 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 | CMOS/TTL-compatible enable input where logic high (at least 2.4V) enables the regulator and logic low (at most 0.8V) shuts it down, with an absolute maximum of -0.3V to VIN. |
| 2 | IN | power_in | Supplies the current to the output power device, with a maximum operating input voltage of 26V. |
| 3 | GND | power_in | Ground pin, with the package tab also connected internally to the IC ground. |
| 4 | OUT | power_out | Regulator output voltage pin, delivering up to 1.5A for the MIC29152. |
| 5 | ADJ | input | Adjustable regulator feedback input that connects to a resistor divider from OUTPUT to GND to set the output voltage, programmable between 1.25V and 25V against a 1.240V typical reference. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

## CAD (KiCad official)

- Symbol: `MIC29152S`
- Footprint: `Package_TO_SOT_SMD:TO-263-5_TabPin6`
- 3D model: TO-263-5 (KiCad packages3D, STEP)
- 3D model files: `mic29152s-etched.step` / `mic29152s-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mic29152s.step` / `mic29152s.glb` are the bare package body.
