LP3980-30B5F

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

LP3980-30B5F 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 IN power_in Power input voltage. Accepts 1.6V to 5.5V. Bypass with a 1uF ceramic capacitor to GND close to the pin. Absolute maximum -0.3V to 6V.
2 GND power_in Ground reference for the regulator.
3 EN input Enable pin. Logic-high (VIH >= 1.4V with VIN=3V-5.5V) turns the regulator on; logic-low (VIL <= 0.4V) puts the device in shutdown mode with <1uA standby current. Absolute maximum -0.3V to 6V. Do not leave floating.
4 NC unconnected No connect. On the fixed-output B5F variants (including LP3980-30B5F, 3.0V fixed output) this pin is not connected internally. Only the adjustable LP3980-AB5F variant uses this pin as the FB feedback input.
5 OUT power_out Regulated output voltage, factory-trimmed to 3.0V for the -30 option. Delivers up to 300mA continuous, current-limited at ~650mA. Requires a 1uF ceramic output capacitor for stability. Auto-discharge resistance ~40 ohm in shutdown.
