Texas Instruments · LDO regulator · SOT-23-5
Low-dropout linear regulator that delivers 200 mA at a fixed 3.3 V from a small SOT-23-5, drawing only about 31 uA of quiescent current so it barely loads a battery in standby. An EN pin shuts it to near zero, internal current limit and thermal shutdown protect it, and it needs only small ceramic input and output capacitors. A cheap, low-power point-of-load LDO for battery sensors and always-on subsystems.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | power_in | Unregulated input supply pin, 2.0 V to 5.5 V (absolute max 6 V). A 1-µF ceramic capacitor from IN to GND is recommended for stability and transient performance. |
| 2 | GND | power_in | Device ground reference pin. |
| 3 | EN | input | Enable input. Driving EN above 0.9 V turns the regulator on; driving EN below 0.4 V places the device into shutdown, reducing operating current to ~1 µA. Absolute max is VIN + 0.3 V or 6 V, whichever is less. |
| 4 | NC | unconnected | No internal connection. May be tied to GND to improve thermal dissipation. |
| 5 | OUT | power_out | Regulated 3.3-V output pin, 200-mA capable. Requires a 1-µF ceramic capacitor from OUT to GND for stability. |
