# TLV70033QDDCRQ1

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TLV70033QDDCRQ1 from Texas Instruments, in a SOT-23-5. 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 | IN | power_in | Input pin for supply voltage; a small 1µF ceramic capacitor is recommended from this pin to ground to provide stability and good transient performance; operating voltage range 2V to 5.5V. |
| 2 | GND | power_in | Ground reference pin. |
| 3 | EN | input | Enable pin; driving EN over 0.9V turns on the regulator; driving EN below 0.4V puts the regulator into shutdown mode and reduces operating current to 1µA nominal. |
| 4 | NC | unconnected | No connection pin; can be tied to ground to improve thermal dissipation. |
| 5 | OUT | power_out | Regulated output voltage pin; a small 1µF ceramic capacitor is needed from this pin to ground to provide stability; maximum output current 200mA. |
