# TPS74522PQWDRVRQ1

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

TPS74522PQWDRVRQ1 from Texas Instruments, in a WSON-6-EP(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 | output | Regulated output voltage pin; requires 1 µF to 220 µF ceramic capacitor from OUT to ground for stability and transient response. |
| 2 | NC | unconnected | No internal connection; grounding this pin improves thermal performance. |
| 3 | GND | power_in | Ground pin; electrically connected to thermal pad for improved heat dissipation. |
| 4 | EN | input | Enable input; drive greater than VEN(HI) to turn on regulator or less than VEN(LO) to enter shutdown mode. |
| 5 | PG | output | Power-good output available in open-drain or push-pull topology for monitoring output voltage status; pullup resistor required only for open-drain type. |
| 6 | IN | power_in | Power supply input pin; requires minimum 1 µF ceramic capacitor from IN to ground; supports 1.5 V to 6.0 V input voltage range. |
| 7 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
