RP114N331D-TR-FF

Ricoh Elec Devices · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

RP114N331D-TR-FF from Ricoh Elec Devices, 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 VDD power_in Input supply pin. Operating range 1.4V to 5.25V (absolute max 6.0V). Bypass to GND with ≥1.0µF ceramic capacitor placed as close as possible to the pin.
2 GND power_in Ground reference pin. Provide a low-impedance return trace to minimize noise pickup and dropout error.
3 CE input Chip Enable pin, active HIGH. VCEH ≥ 1.0V enables the regulator; VCEL ≤ 0.4V places the device in standby (Istandby typ 0.1µA). Internal pull-down ~0.3µA (typ). Absolute max 6.0V.
4 NC unconnected No Connection. Pin is not internally bonded; may be left floating or tied to GND for mechanical stability.
5 VOUT power_out Regulated 3.3V output pin (RP114x33xx). Sources up to 300mA continuous. Requires a ≥1.0µF ceramic output capacitor for phase compensation, placed as close to the pin as possible. D-version includes an internal Nch auto-discharge switch (~50Ω) that pulls VOUT to GND when CE is de-asserted.
