# LP591250MDRVREP

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · WSON-6(2x2)

LP591250MDRVREP from Texas Instruments, in a WSON-6(2x2). 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 | OUT | power_out | Regulated output voltage; the output is specified from 0.8 V to 5.5 V, with an internal 100-Ω automatic discharge pulldown that is active when EN is low. |
| 2 | NC | unconnected | No internal connection; leave open or connect to ground. |
| 3 | PG | output | Power-good indicator, open-drain output that requires an external pullup resistor; the datasheet recommends a pullup from 10 kΩ to 100 kΩ, and PG is pulled low when the device is disabled. |
| 4 | EN | input | Enable input: logic high turns the device on and logic low turns it off, with an internal 3-MΩ pulldown to GND; EN must stay between 0 V and VIN. |
| 5 | GND | power_in | Ground reference for all device voltages; the thermal pad must be connected to ground or left floating. |
| 6 | IN | power_in | Unregulated input voltage; the recommended operating input range is 1.6 V to 6.5 V, with an absolute maximum of 7 V. |
| 7 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
