STLQ015M28R

STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L

STLQ015M28R from STMicroelectronics, in a SOT-23-5L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN power_in Unregulated input supply. Operating input voltage range 1.5 V to 5.5 V (absolute max 7 V). Bypass to GND with a 1 µF ceramic capacitor per typical application.
2 GND power_in Device ground reference. All voltages are referred to this pin.
3 EN input Enable input. VEN >= 0.7 V turns the regulator on; VEN <= 0.4 V places the device in shutdown (IN current drops to ~1 nA typ). Absolute max is VIN+0.3 V. Do not leave floating.
4 NC unconnected Not connected. Leave floating or tie to GND; no internal bond.
5 OUT power_out Regulated output voltage (2.8 V nominal for STLQ015M28R, +/-2% at 25 degC). Guaranteed for up to 150 mA load. Requires a ceramic output capacitor (typ 1 µF; 0.47 to 10 µF, ESR 0.056 to 6 ohm) for stability.
