# TPS73533DRBT

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · VSON-8-EP(3x3)

TPS73533DRBT from Texas Instruments, in a VSON-8-EP(3x3). 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 | Output pin requiring 2.2-μF minimum ceramic capacitor to ground for stability. |
| 2 | NC | unconnected | Not internally connected. |
| 3 | NR | passive | Noise reduction pin for fixed voltage versions accepting up to 0.01 μF external capacitor to reduce output noise. |
| 4 | GND | power_in | Ground pin; must be tied to ground. |
| 5 | EN | input | Enable input pin; high enables regulator, low initiates shutdown mode, or can be tied to IN if unused. |
| 6 | NC | unconnected | Not internally connected. |
| 7 | NC | unconnected | Not internally connected. |
| 8 | IN | power_in | Input supply pin requiring 0.1-µF to 1-µF low ESR capacitor to ground near device. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
