# UR132G-18-AE3-3-R

**UTC Unisonic Tech** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23

UR132G-18-AE3-3-R from UTC Unisonic Tech, in a SOT-23. 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 | GND | power_in | Ground reference pin for the regulator; the datasheet specifies a 10µF (or larger) output capacitor and a 1µF (or larger) input capacitor, both referenced to GND. |
| 2 | VOUT | power_out | Regulated output pin, rated for a guaranteed 200mA output current, with a 10µF (or larger) capacitor recommended between VOUT and GND for stability. |
| 3 | VIN | power_in | Unregulated input pin, with an input voltage range up to 12V and an absolute maximum rating of -0.3 to 12 V, with a 1µF (or larger) capacitor recommended between VIN and GND. |
