LP3201SAB5F

LOWPOWER · DC-DC Converters · SOT-23-5

LP3201SAB5F from LOWPOWER, in a SOT-23-5. 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 EN input Enable input, active high. Threshold VIL <= 0.4V, VIH >= 1.4V. Pulling low forces the device into shutdown with <1uA supply current; must not be left floating.
2 GND power_in Device ground return. Connect to the ground plane close to the input capacitor for proper power filtering.
3 LX output Switch node connected to the drains of the internal P-channel main and N-channel synchronous power MOSFETs. Connects to the external inductor (typ. 2.2uH); trace should be kept short to reduce EMI.
4 VIN power_in Power-supply input, 2.5V to 6.5V (absolute max 8V, OVP typ. 7V). Must be decoupled to GND with a 10uF or greater ceramic capacitor placed close to the pin.
5 FB input Feedback input to the internal error amplifier; regulates to VREF = 0.6V (0.588V-0.612V). Connect the mid-point of the RUP/RDN divider (VOUT = 0.6V x (1 + RUP/RDN)); recommended RDN >= 59k.
