**TECH PUBLIC** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DFN-4(1x1)

TP132LC25D4 from TECH PUBLIC, in a DFN-4(1x1). 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 | VOUT | power_out | Regulated output pin (2.5V version for TP132LC25D4), with a 1µF ceramic output capacitor shown in the typical application circuit; VOUT range -0.3V to VIN+0.3V absolute maximum. |
| 2 | VSS/GND | power_in | Ground pin, connected to the system ground in the typical application circuit. |
| 3 | CE | input | Chip enable pin; CE high voltage is 1.5V min up to VIN and CE low voltage is 0.3V max, with standby current of 0.1µA max when CE=VSS. |
| 4 | VIN | power_in | Power input pin, operating input range 1.8V to 7.0V with an absolute maximum of 7V and a 1µF ceramic input capacitor shown in the typical application circuit. |
| 5 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
